The Romance languages (nowadays rarely Romanic languages, Latin languages, Neo-Latin languages) are the modern languages that evolved from Vulgar Latin between the third and eighth centuries and that form a subgroup of the Italic languages within the Indo-European language family.
Today, around 800 million people are native speakers worldwide, mainly in Europe, Africa, and the Americas, but also elsewhere. Additionally, the major Romance languages have many non-native speakers and are in widespread use as lingua francas. This is especially the case for French, which is in widespread use throughout Central and West Africa, Madagascar, Mauritius, and the Maghreb.
The five most widely spoken Romance languages by number of native speakers are Spanish (470 million), Portuguese (250 million), French (150 million), Italian (90 million), and Romanian (25 million).
Because of the difficulty of imposing boundaries on a continuum, various counts of the modern Romance languages are given; for example, Dalby lists 23 based on mutual intelligibility. The following, more extensive list, includes 35 current, living languages, and one extinct language, Dalmatian:
Romance languages are the continuation of Vulgar Latin, the popular and colloquial sociolect of Latin spoken by soldiers, settlers, and merchants of the Roman Empire, as distinguished from the classical form of the language spoken by the Roman upper classes, the form in which the language was generally written. Between 350 BC and 150 AD, the expansion of the Empire, together with its administrative and educational policies, made Latin the dominant native language in continental Western Europe. Latin also exerted a strong influence in southeastern Britain, the Roman province of Africa, western Germany, Pannonia and the whole Balkans.
During the Empire's decline, and after its fragmentation and the collapse of Western half in the fifth and sixth centuries, the spoken varieties of Latin became more isolated from each other, with the western dialects coming under heavy Germanic influence (the Goths and Franks in particular) and the eastern dialects coming under Slavic influence. The dialects diverged from classical Latin at an accelerated rate and eventually evolved into a continuum of recognizably different typologies. The colonial empires established by Portugal, Spain, and France from the fifteenth century onward spread their languages to the other continents to such an extent that about two-thirds of all Romance language speakers today live outside Europe.
Despite other influences (e.g. substratum from pre-Roman languages, especially Continental Celtic languages; and superstratum from later Germanic or Slavic invasions), the phonology, morphology, and lexicon of all Romance languages consist mainly of evolved forms of Vulgar Latin. However, some notable differences occur between today's Romance languages and their Roman ancestor. With only one or two exceptions, Romance languages have lost the declension system of Latin and, as a result, have SVO sentence structure and make extensive use of prepositions.
The term Romance comes from the Vulgar Latin adverb romanice, "in Roman", derived from Romanicus: for instance, in the expression romanice loqui, "to speak in Roman" (that is, the Latin vernacular), contrasted with latine loqui, "to speak in Latin" (Medieval Latin, the conservative version of the language used in writing and formal contexts or as a lingua franca), and with barbarice loqui, "to speak in Barbarian" (the non-Latin languages of the peoples living outside the Roman Empire). From this adverb the noun romance originated, which applied initially to anything written romanice, or "in the Roman vernacular".
The word 'romance' with the modern sense of romance novel or love affair has the same origin. In the medieval literature of Western Europe, serious writing was usually in Latin, while popular tales, often focusing on heroic adventures and courtly love, were composed in the vernacular and came to be called "romances".
Lexical and grammatical similarities among the Romance languages, and between Latin and each of them, are apparent from the following examples having the same meaning in various Romance lects:
English: She always closes the window before she dines / before dining.
Some of the divergence comes from semantic change: where the same root word has developed different meanings. For example, the Portuguese word fresta is descended from Latin fenestra "window" (and is thus cognate to French fenêtre, Italian finestra, Romanian fereastră and so on), but now means "skylight" and "slit". Cognates may exist but have become rare, such as finiestra in Spanish, or dropped out of use entirely. The Spanish and Portuguese terms defenestrar meaning "to throw through a window" and fenestrado meaning "replete with windows" also have the same root, but are later borrowings from Latin.
Likewise, Portuguese also has the word cear, a cognate of Italian cenare and Spanish cenar, but uses it in the sense of "to have a late supper" in most varieties, while the preferred word for "to dine" is jantar (related to archaic Spanish yantar "to eat") because of semantic changes in the 19th century. Galician has both fiestra (from medieval fẽestra, the ancestor of standard Portuguese fresta) and the less frequently used ventá and xanela.
As an alternative to lei (originally the genitive form), Italian has the pronoun ella, a cognate of the other words for "she", but it is hardly ever used in speaking.
Spanish, Asturian, and Leonese ventana and Mirandese and Sardinian bentana come from Latin ventus "wind" (cf. English window, etymologically 'wind eye'), and Portuguese janela, Galician xanela, Mirandese jinela from Latin *ianuella "small opening", a derivative of ianua "door".
Sardinian balcone (alternative for ventàna/bentàna) comes from Old Italian and is similar to other Romance languages such as French balcon (from Italian balcone), Portuguese balcão, Romanian balcon, Spanish balcón, Catalan balcó and Corsican balconi (alternative for purtellu).
Documentary evidence is limited about Vulgar Latin for the purposes of comprehensive research, and the literature is often hard to interpret or generalize. Many of its speakers were soldiers, slaves, displaced peoples, and forced resettlers, more likely to be natives of conquered lands than natives of Rome. In Western Europe, Latin gradually replaced Celtic and other Italic languages, which were related to it by a shared Indo-European origin. Commonalities in syntax and vocabulary facilitated the adoption of Latin.
Vulgar Latin is believed to have already had most of the features shared by all Romance languages, which distinguish them from Classical Latin, such as the almost complete loss of the Latin grammatical case system and its replacement by prepositions; the loss of the neuter grammatical gender and comparative inflections; replacement of some verb paradigms by innovations (e.g. the synthetic future gave way to an originally analytic strategy now typically formed by infinitive + evolved present indicative forms of 'have'); the use of articles; and the initial stages of the palatalization of the plosives /k/, /g/, and /t/.
To some scholars, this suggests the form of Vulgar Latin that evolved into the Romance languages was around during the time of the Roman Empire (from the end of the first century BC), and was spoken alongside the written Classical Latin which was reserved for official and formal occasions. Other scholars argue that the distinctions are more rightly viewed as indicative of sociolinguistic and register differences normally found within any language. Both were mutually intelligible as one and the same language, which was true until very approximately the second half of the 7th century. However, within two hundred years Latin became a dead language since "the Romanized people of Europe could no longer understand texts that were read aloud or recited to them," i.e. Latin had ceased to be a first language and became a foreign language that had to be learned, if the label Latin is constrained to refer to a state of the language frozen in past time and restricted to linguistic features for the most part typical of higher registers.
During the political decline of the Western Roman Empire in the fifth century, there were large-scale migrations into the empire, and the Latin-speaking world was fragmented into several independent states. Central Europe and the Balkans were occupied by Germanic and Slavic tribes, as well as by Huns. These incursions isolated the Vlachs from the rest of Romance-speaking Europe.
British and African Romance—the forms of Vulgar Latin used in southeastern Britain and the Roman province of Africa, where it had been spoken by much of the urban population—disappeared in the Middle Ages (as did Pannonian Romance in what is now Hungary, and Moselle Romance in Germany). But the Germanic tribes that had penetrated Roman Italy, Gaul, and Hispania eventually adopted Latin/Romance and the remnants of the culture of ancient Rome alongside existing inhabitants of those regions, and so Latin remained the dominant language there. In part due to regional dialects of the Latin language and local environments, several languages evolved from it.:4
Meanwhile, large-scale migrations into the Eastern Roman Empire started with the Goths and continued with Huns, Avars, Bulgars, Slavs, Pechenegs, Hungarians and Cumans. The invasions of Slavs were the most thoroughgoing, and they partially reduced the Romanic element in the Balkans. The invasion of the Turks and conquest of Constantinople in 1453 marked the end of the empire. The Slavs named the Romance-speaking population Vlachs, while the latter called themselves "Rumân" or "Român", from the Latin "Romanus" The Daco-Roman dialect became fully distinct from the three dialects spoken South of the Danube—Macedo-Romanian, Istro-Romanian, and Megleno-Romanian—during the ninth and tenth centuries, when the Romanians (sometimes called Vlachs or Wallachians) emerged as a people.
Over the course of the fourth to eighth centuries, local changes in phonology, morphology, syntax and lexicon accumulated to the point that the speech of any locale was noticeably different from another. In principle, differences between any two lects increased the more they were separated geographically, reducing easy mutual intelligibility between speakers of distant communities. Clear evidence of some levels of change is found in the Reichenau Glosses, an eighth-century compilation of about 1,200 words from the fourth-century Vulgate of Jerome that had changed in phonological form or were no longer normally used, along with their eighth-century equivalents in proto-Franco-Provençal. The following are some examples with reflexes in several modern Romance languages for comparison:
In all of the above examples, the words appearing in the fourth century Vulgate are the same words as would have been used in Classical Latin of c. 50 BC. It is likely that some of these words had already disappeared from casual speech by the time of the Glosses; but if so, they may well have been still widely understood, as there is no recorded evidence that the common people of the time had difficulty understanding the language.
By the 8th century, the situation was very different. During the late 8th century, Charlemagne, holding that "Latin of his age was by classical standards intolerably corrupt",:6 successfully imposed Classical Latin as an artificial written vernacular for Western Europe. Unfortunately, this meant that parishioners could no longer understand the sermons of their priests, forcing the Council of Tours in 813 to issue an edict that priests needed to translate their speeches into the rustica romana lingua, an explicit acknowledgement of the reality of the Romance languages as separate languages from Latin.:6
By this time, and possibly as early as the 6th century according to Price (1984),:6 the Romance lects had split apart enough to be able to speak of separate Gallo-Romance, Ibero-Romance, Italo-Romance and Eastern Romance languages. Some researchers[who?] have postulated that the major divergences in the spoken dialects began or accelerated considerably in the 5th century, as the formerly widespread and efficient communication networks of the Western Roman Empire rapidly broke down, leading to the total disappearance of the Western Roman Empire by the end of the century. The critical period between the 5th–10th centuries AD is poorly documented because little or no writing from the chaotic "Dark Ages" of the 5th–8th centuries has survived, and writing after that time was in consciously classicized Medieval Latin, with vernacular writing only beginning in earnest in the 11th or 12th centuries. An exception such as the Oaths of Strasbourg is evidence that by the ninth century effective communication with a non-learnèd audience was carried out in evolved Romance.
A language that was closely related to medieval Romanian was spoken during the Dark Ages by Vlachs in the Balkans, Herzegovina, Dalmatia (Morlachs), Ukraine (Hutsuls), Poland (Gorals), Slovakia, and Czech Moravia, but gradually these communities lost their maternal language.
Between the 10th and 13th centuries, some local vernaculars developed a written form and began to supplant Latin in many of its roles. In some countries, such as Portugal, this transition was expedited by force of law; whereas in others, such as Italy, many prominent poets and writers used the vernacular of their own accord – some of the most famous in Italy being Giacomo da Lentini and Dante Alighieri. Well before that, the vernacular was also used for practical purposes, such as the testimonies in the Placiti Cassinesi, written 960-963.
The invention of the printing press brought a tendency towards greater uniformity of standard languages within political boundaries, at the expense of other Romance languages and dialects less favored politically. In France, for instance, the dialect spoken in the region of Paris gradually spread to the entire country, and the Occitan of the south lost ground.
The Romance language most widely spoken natively today is Spanish, followed by Portuguese, French, Italian and Romanian, which together cover a vast territory in Europe and beyond, and work as official and national languages in dozens of countries.
French, Italian, Portuguese, Spanish, and Romanian are also official languages of the European Union. Spanish, Portuguese, French, Italian, Romanian, and Catalan are the official languages of the Latin Union; and French and Spanish are two of the six official languages of the United Nations. Outside Europe, French, Portuguese and Spanish are spoken and enjoy official status in various countries that emerged from the respective colonial empires.
Spanish is an official language in Spain and in nine countries of South America, home to about half that continent's population; in six countries of Central America (all except Belize); and in Mexico. In the Caribbean, it is official in Cuba, the Dominican Republic, and Puerto Rico. In all these countries, Latin American Spanish is the vernacular language of the majority of the population, giving Spanish the most native speakers of any Romance language. In Africa it is an official language of Equatorial Guinea.
Portuguese, in its original homeland, Portugal, is spoken by virtually the entire population of 10 million. As the official language of Brazil, it is spoken by more than 200 million people in that country, as well as by neighboring residents of eastern Paraguay and northern Uruguay, accounting for a little more than half the population of South America. It is the official language of six African countries (Angola, Cape Verde, Guinea-Bissau, Mozambique, Equatorial Guinea, and São Tomé and Príncipe), and is spoken as a first language by perhaps 30 million residents of that continent. In Asia, Portuguese is co-official with other languages in East Timor and Macau, while most Portuguese-speakers in Asia—some 400,000—are in Japan due to return immigration of Japanese Brazilians. In North America 1,000,000 people speak Portuguese as their home language. In Oceania, Portuguese is the second most spoken Romance language, after French, due mainly to the number of speakers in East Timor. Its closest relative, Galician, has official status in the autonomous community of Galicia in Spain, together with Spanish.
Outside Europe, French is spoken natively most in the Canadian province of Quebec, and in parts of New Brunswick and Ontario. Canada is officially bilingual, with French and English being the official languages. In parts of the Caribbean, such as Haiti, French has official status, but most people speak creoles such as Haitian Creole as their native language. French also has official status in much of Africa, but relatively few native speakers. In France's overseas possessions, native use of French is increasing.
Although Italy also had some colonial possessions before World War II, its language did not remain official after the end of the colonial domination. As a result, Italian outside of Italy and Switzerland is now spoken only as a minority language by immigrant communities in North and South America and Australia. In some former Italian colonies in Africa—namely Libya, Eritrea and Somalia—it is spoken by a few educated people in commerce and government.
Romania did not establish a colonial empire, but beyond its native territory in southeastern Europe, the Romanian language is spoken as a minority language by autochthonous populations in Serbia, Bulgaria, and Hungary, and in some parts of the former Greater Romania (before 1945), as well as in Ukraine (Bukovina, Budjak) and in some villages between the Dniester and Bug rivers. The Aromanian language is spoken today by Aromanians in Bulgaria, Macedonia, Albania, Kosovo, and Greece. Romanian also spread to other countries on the Mediterranean (especially the other Romance-speaking countries, most notably Italy and Spain), and elsewhere such as Israel, where it is the native language of five percent of the population, and is spoken by many more as a secondary language. This is due to the large number of Romanian-born Jews who moved to Israel after World War II. And finally, some 2.6 million people in the former Soviet republic of Moldova speak a variety of Romanian, called variously Moldovan or Romanian by them.
Catalan is the official language of Andorra. In Spain, it is co-official with Spanish in Catalonia, the Valencian Community, and the Balearic Islands, and it is recognized, but not official, in La Franja, and in Aragon. In addition, it is spoken by many residents of Alghero, on the island of Sardinia, and it is co-official in that city. Galician, with more than a million native speakers, is official together with Spanish in Galicia, and has legal recognition in neighbouring territories in Castilla y León. A few other languages have official recognition on a regional or otherwise limited level; for instance, Asturian and Aragonese in Spain; Mirandese in Portugal; Friulan, Sardinian and Franco-Provençal in Italy; and Romansh in Switzerland.
The remaining Romance languages survive mostly as spoken languages for informal contact. National governments have historically viewed linguistic diversity as an economic, administrative or military liability, as well as a potential source of separatist movements; therefore, they have generally fought to eliminate it, by extensively promoting the use of the official language, restricting the use of the other languages in the media, recognizing them as mere "dialects", or even persecuting them. As a result, all of these languages are considered endangered to varying degrees according to the UNESCO Red Book of Endangered Languages, ranging from "vulnerable" (e.g. Sicilian and Venetian) to "severely endangered" (Arpitan, most of the Occitan varieties). Since the late twentieth and early twenty-first centuries, increased sensitivity to the rights of minorities has allowed some of these languages to start recovering their prestige and lost rights. Yet it is unclear whether these political changes will be enough to reverse the decline of minority Romance languages.
The classification of the Romance languages is inherently difficult, because most of the linguistic area is a dialect continuum, and in some cases political biases can come into play. Along with Latin (which is not included among the Romance languages) and a few extinct languages of ancient Italy, they make up the Italic branch of the Indo-European family.
There are various schemes used to subdivide the Romance languages. Three of the most common schemes are as follows:
The main subfamilies that have been proposed by Ethnologue within the various classification schemes for Romance languages are:
This three-way division is made primarily based on the outcome of Vulgar Latin (Proto-Romance) vowels:
Italo-Western is in turn split along the so-called La Spezia–Rimini Line in northern Italy, which divides the central and southern Italian languages from the so-called Western Romance languages to the north and west. The primary characteristics dividing the two are:
The reality is somewhat more complex. All of the "southeast" characteristics apply to all languages southeast of the line, and all of the "northwest" characteristics apply to all languages in France and (most of) Spain. However, the Gallo-Italic languages are somewhere in between. All of these languages do have the "northwest" characteristics of lenition and loss of gemination. However:
On top of this, the ancient Mozarabic language in southern Spain, at the far end of the "northwest" group, had the "southeast" characteristics of lack of lenition and palatalization of /k/ to /tʃ/. Certain languages around the Pyrenees (e.g. some highland Aragonese dialects) also lack lenition, and northern French dialects such as Norman and Picard have palatalization of /k/ to /tʃ/ (although this is possibly an independent, secondary development, since /k/ between vowels, i.e. when subject to lenition, developed to /dz/ rather than /dʒ/, as would be expected for a primary development).
The usual solution to these issues is to create various nested subgroups. Western Romance is split into the Gallo-Iberian languages, in which lenition happens and which include nearly all the Western Romance languages, and the Pyrenean-Mozarabic group, which includes the remaining languages without lenition (and is unlikely to be a valid clade; probably at least two clades, one for Mozarabic and one for Pyrenean). Gallo-Iberian is split in turn into the Iberian languages (e.g. Spanish and Portuguese), and the larger Gallo-Romance languages (stretching from eastern Spain to northeast Italy).
Probably a more accurate description, however, would be to say that there was a focal point of innovation located in central France, from which a series of innovations spread out as areal changes. The La Spezia–Rimini Line represents the farthest point to the southeast that these innovations reached, corresponding to the northern chain of the Apennine Mountains, which cuts straight across northern Italy and forms a major geographic barrier to further language spread.
This would explain why some of the "northwest" features (almost all of which can be characterized as innovations) end at differing points in northern Italy, and why some of the languages in geographically remote parts of Spain (in the south, and high in the Pyrenees) are lacking some of these features. It also explains why the languages in France (especially standard French) seem to have innovated earlier and more completely than other Western Romance languages.
Many of the "southeast" features also apply to the Eastern Romance languages (particularly, Romanian), despite the geographic discontinuity. Examples are lack of lenition, maintenance of intertonic vowels, use of vowel-changing plurals, and palatalization of /k/ to /tʃ/. (Gemination is missing, which may be an independent development, and /kt/ develops into /pt/ rather than either of the normal Italo-Western developments.) This has led some researchers to postulate a basic two-way East-West division, with the "Eastern" languages including Romanian and central and southern Italian.
Despite being the first Romance language to evolve from Vulgar Latin,[dubious ] Sardinian does not fit at all into this sort of division. It is clear that Sardinian became linguistically independent from the remainder of the Romance languages at an extremely early date, possibly already by the first century BC. Sardinian contains a large number of archaic features, including total lack of palatalization of /k/ and /g/ and a large amount of vocabulary preserved nowhere else, including some items already archaic by the time of Classical Latin (first century BC). Sardinian has plurals in /s/ but post-vocalic lenition of voiceless consonants is normally limited to the status of an allophonic rule (e.g. [k]ane 'dog' but su [g]ane or su [ɣ]ane 'the dog'), and there are a few innovations unseen elsewhere, such as a change of /au/ to /a/. Use of su < ipsum as an article is a retained archaic feature that also exists in the Catalan of the Balearic Islands and that used to be more widespread in Occitano-Romance, and is known as article salat (literally the "salted article"), while Sardinian shares delabialization of earlier /kw/ and /gw/ with Romanian: Sard. abba, Rum. apă 'water'; Sard. limba, Rom. limbă 'language' (cf. Italian acqua, lingua).
The following groups are also sometimes considered part of Gallo-Romance:
The Gallo-Romance languages are generally considered the most innovative (least conservative) among the Romance languages. Characteristic Gallo-Romance features generally developed earliest and appear in their most extreme manifestation in the Langue d'oïl, gradually spreading out along riverways and transalpine roads.
In some ways, however, the Gallo-Romance languages are conservative. The older stages of many of the languages preserved a two-case system consisting of nominative and oblique, fully marked on nouns, adjectives and determiners, inherited almost directly from the Latin nominative and accusative and preserving a number of different declensional classes and irregular forms. The languages closest to the oïl epicenter preserve the case system the best, while languages at the periphery lose it early.
Some Romance languages have developed varieties which seem dramatically restructured as to their grammars or to be mixtures with other languages. It is not always clear whether they should be classified as Romance, pidgins, creole languages, or mixed languages. Some other languages, such as Modern English, are sometimes thought of as creoles of semi-Romance ancestry. There are several dozens of creoles of French, Spanish, and Portuguese origin, some of them spoken as national languages in former European colonies.
The concept was first developed in 1903 by Italian mathematician Giuseppe Peano, under the title Latino sine flexione. He wanted to create a naturalistic international language, as opposed to an autonomous constructed language like Esperanto or Volapuk which were designed for maximal simplicity of lexicon and derivation of words. Peano used Latin as the base of his language, because at the time of his flourishing it was the de facto international language of scientific communication.
Other languages developed since include Idiom Neutral, Occidental, Lingua Franca Nova, and most famously and successfully, Interlingua. Each of these languages has attempted to varying degrees to achieve a pseudo-Latin vocabulary as common as possible to living Romance languages.
There are also languages created for artistic purposes only, such as Talossan. Because Latin is a very well attested ancient language, some amateur linguists have even constructed Romance languages that mirror real languages that developed from other ancestral languages. These include Brithenig (which mirrors Welsh), Breathanach (mirrors Irish), Wenedyk (mirrors Polish), Þrjótrunn (mirrors Icelandic), and Helvetian (mirrors German).
Romance languages have a number of shared features across all languages:
The most significant changes between Classical Latin and Proto-Romance (and hence all the modern Romance languages) relate to the reduction or loss of the Latin case system, and the corresponding syntactic changes that were triggered.
The case system was drastically reduced from the six-case system of Classical Latin. Although five cases can be reconstructed for Vulgar Latin nouns (nominative, accusative, genitive, dative, and ablative), for Proto-Romance this had been reduced to three: nominative, accusative-ablative, and genitive-dative. This system is preserved best in pronouns. In the West, the genitive-dative disappeared with the genitive replaced by de + ablative and the dative by ad + accusative. This left only two cases: nominative and oblique. Some of the older Gallo-Romance languages (in particular, Old French, Old Occitan, Old Sursilvan and Old Friulian, and in traces Old Catalan and Old Venetian) preserved this two-case system well into the literary period, and in Ibero-Romance languages, such as Spanish and Portuguese, as well as in Italian (see under Case), a couple of examples are found which preserve the old nominative. In the East, a genitive-dative made entirely of dative forms was retained but the nominative and accusative-ablative eventually merged.
Concomitant with the loss of cases, freedom of word order was greatly reduced. Classical Latin had a generally verb-final (SOV) but overall quite free word order, with a significant amount of word scrambling and mixing of left-branching and right-branching constructions. The Romance languages eliminated word scrambling and nearly all left-branching constructions, with most languages developing a rigid SVO, right-branching syntax. (Old French, however, had a freer word order due to the two-case system still present, as well as a predominantly verb-second word order developed under the influence of the Germanic languages.) Some freedom, however, is allowed in the placement of adjectives relative to their head noun. In addition, some languages (e.g. Spanish, Romanian) have an "accusative preposition" (Romanian pe, Spanish "personal a") along with clitic doubling, which allows for some freedom in ordering the arguments of a verb.
The Romance languages developed grammatical articles where Latin had none. Articles are often introduced around the time a robust case system falls apart in order to disambiguate the remaining case markers (which are usually too ambiguous by themselves) and to serve as parsing clues that signal the presence of a noun (a function that used to be served by the case endings themselves).
This was the pattern followed by the Romance languages: In the Romance languages that still preserved a functioning nominal case system (e.g., Romanian and Old French), only the combination of article and case ending serves to uniquely identify number and case (compare the similar situation in modern German). All Romance languages have a definite article (originally developed from ipse "self" but replaced in nearly all languages by ille "that (over there)") and an indefinite article (developed from ūnus "one"). Many also have a partitive article (dē "of" + definite article).
Latin had a large number of syntactic constructions expressed through infinitives, participles, and similar nominal constructs. Examples are the ablative absolute, the accusative-plus-infinitive construction used for reported speech, gerundive constructions, and the common use of reduced relative clauses expressed through participles. All of these are replaced in the Romance languages by subordinate clauses expressed with finite verbs, making the Romance languages much more "verbal" and less "nominal" than Latin. Under the influence of the Balkan sprachbund, Romanian has progressed the furthest, largely eliminating the infinitive. (It is being revived, however, due to the increasing influence of other Romance languages.)
Every language has a different set of vowels from every other. Common characteristics are as follows:
Most Romance languages have similar sets of consonants. The following is a combined table of the consonants of the five major Romance languages (French, Spanish, Italian, Portuguese, Romanian).
Most instances of most of the sounds below that occur (or used to occur, as described above) in all of the languages are cognate. However:
Word stress was rigorously predictable in classical Latin except in a very few exceptional cases, either on the penultimate syllable (second from last) or antepenultimate syllable (third from last), according to the syllable weight of the penultimate syllable. Stress in the Romance Languages mostly remains on the same syllable as in Latin, but various sound changes have made it no longer so predictable. Minimal pairs distinguished only by stress exist in some languages, e.g. Italian Papa [ˈpa.pa] "Pope" vs. papà [pa.ˈpa] "daddy", or Spanish límite [ˈli.mi.te] "[a] limit", present subjunctive limite [li.ˈmi.te] "[that] [I/he] limit" and preterite limité [li.mi.ˈte] "[I] limited".
Erosion of unstressed syllables following the stress has caused most Spanish and Portuguese words to have either penultimate or ultimate stress: e.g. Latin trēdecim "thirteen" > Spanish trece, Portuguese treze; Latin amāre "to love" > Spanish/Portuguese amar. Most words with antepenultimate stress are learned borrowings from Latin, e.g. Spanish/Portuguese fábrica "factory" (the corresponding inherited word is Spanish fragua, Portuguese frágua "forge"). This process has gone even farther in French, with deletion of all post-stressed vowels, leading to consistent, predictable stress on the last syllable: e.g. Latin Stephanum "Stephen" > Old French Estievne > French Étienne /e.ˈtjɛn/; Latin juvenis "young" > Old French juevne > French jeune /ʒœn/. This applies even to borrowings: e.g. Latin fabrica > French borrowing fabrique /fa.ˈbʀik/ (the inherited word in this case being monosyllabic forge < Pre-French *fauriga).
Other than French (with consistent final stress), the position of the stressed syllable generally falls on one of the last three syllables. Exceptions may be caused by clitics or (in Italian) certain verb endings, e.g. Italian telefonano [teˈlɛ.fo.na.no] "they telephone"; Spanish entregándomelo [en.tɾe.ˈɣan.do.me.lo] "delivering it to me"; Italian mettiamocene [meˈtːjaː.mo.tʃe.ne] "let's put some of it in there"; Portuguese dávamos-vo-lo [ˈda.vɐ.muʃ.vu.lu] "we were giving it to you". Stress on verbs is almost completely predictable in Spanish and Portuguese, but less so in Italian.
The Romance languages inherited from Latin two grammatical numbers, singular and plural; the only trace of a dual number comes from Latin ambō > Spanish and Portuguese ambos, Old Romanian îmbi > Romanian ambii, Old French ambe, Italian ambedue, entrambi.
Most Romance languages have two grammatical genders, masculine and feminine. The gender of animate nouns is generally natural (i.e. nouns referring to men are generally masculine, and vice versa), but for nonanimate nouns it is arbitrary.
Although Latin had a third gender (neuter), there is little trace of this in most languages. The biggest exception is Romanian, where there is a productive class of "neuter" nouns, which include the descendants of many Latin neuter nouns and which behave like masculines in the singular and feminines in the plural, both in the endings used and in the agreement of adjectives and pronouns (e.g. un deget "one finger" vs. două degete "two fingers", cf. Latin digitus, pl. digiti).
Such nouns arose because of the identity of the Latin neuter singular -um with the masculine singular, and the identity of the Latin neuter plural -a with the feminine singular. A similar class exists in Italian, although it is no longer productive (e.g. il dito "the finger" vs. le dita "the fingers", l'uovo "the egg" vs. le uova "the eggs"). A similar phenomenon may be observed in Albanian (which is heavily Romance-influenced), and the category remains highly productive with a number of new words loaned or coined in the neuter ((një) hotel one hotel(m) vs. (tri) hotele three hotels (f)). (A few isolated nouns in Latin had different genders in the singular and plural, but this was an unrelated phenomenon; this is similarly the case with a few French nouns, such as amour, délice, orgue.)
Spanish also has vestiges of the neuter in the demonstrative adjectives: esto, eso, aquello, the pronoun ello (meaning "it") and the article lo (used to intensify adjectives). Portuguese also has neuter demonstrative adjectives: "isto", "isso", "aquilo" (meaning "this [near me]", "this/that [near you]", "that [far from the both of us]").
Remnants of the neuter, interpretable now as "a sub-class of the non-feminine gender" (Haase 2000:233), are vigorous in Italy in an area running roughly from Ancona to Matera and just north of Rome to Naples. Oppositions with masculine typically have been recategorized, so that neuter signifies the referent in general, while masculine indicates a more specific instance, with the distinction marked by the definite article. In Southeast Umbrian, for example, neuter lo pane is 'the bread', while masculine lu pane refers to an individual piece or loaf of bread. Similarly, neuter lo vinu is wine in general, while masculine lu vinu is a specific sort of wine, with the consequence that mass lo vinu has no plural counterpart, but lu vinu can take a sortal plural form li vini, referring to different types of wine. Phonological forms of articles vary by locale.
Latin had an extensive case system, where all nouns were declined in six cases (nominative, vocative, accusative, dative, genitive, and ablative) and two numbers. Many adjectives were additionally declined in three genders, leading to a possible 6 × 2 × 3 = 36 endings per adjective (although this was rarely the case). In practice, some category combinations had identical endings to other combinations, but a basic adjective like bonus "good" still had 14 distinct endings.
In all Romance languages, this system was drastically reduced. In most modern Romance languages, in fact, case is no longer marked at all on nouns, adjectives and determiners, and most forms are derived from the Latin accusative case. Much like English, however, case has survived somewhat better on pronouns.
Most pronouns have distinct nominative, accusative, genitive and possessive forms (cf. English "I, me, mine, my"). Many also have a separate dative form, a disjunctive form used after prepositions, and (in some languages) a special form used with the preposition con "with" (a conservative feature inherited from Latin forms such as mēcum, tēcum, nōbīscum).
The system of inflectional classes is also drastically reduced. The basic system is most clearly indicated in Spanish, where there are only three classes, corresponding to the first, second and third declensions in Latin: plural in -as (feminine), plural in -os (masculine), plural in -es (either masculine or feminine). The singular endings exactly track the plural, except the singular -e is dropped after certain consonants.
The same system underlines many other modern Romance languages, such as Portuguese, French and Catalan. In these languages, however, further sound changes have resulted in various irregularities. In Portuguese, for example, loss of /l/ and /n/ between vowels (with nasalization in the latter case) produces various irregular plurals (nação – nações "nation(s)"; hotel – hotéis "hotel(s)").
In French and Catalan, loss of /o/ and /e/ in most unstressed final syllables has caused the -os and -es classes to merge. In French, merger of remaining /e/ with final /a/ into [ə], and its subsequent loss, has completely obscured the original Romance system, and loss of final /s/ has caused most nouns to have identical pronunciation in singular and plural, although they are still marked differently in spelling (e.g. femme – femmes "woman – women", both pronounced /fam/).
Noun inflection has survived in Romanian somewhat better than elsewhere.:399 Determiners are still marked for two cases (nominative/accusative and genitive/dative) in both singular and plural, and feminine singular nouns have separate endings for the two cases. In addition, there is a separate vocative case, enriched with native development and Slavic borrowings (see some examples here) and the combination of noun with a following clitic definite article produces a separate set of "definite" inflections for nouns.
The inflectional classes of Latin have also survived more in Romanian than elsewhere, e.g. om – oameni "man – men" (Latin homo – homines); corp – corpuri "body – bodies" (Latin corpus – corpora). (Many other exceptional forms, however, are due to later sound changes or analogy, e.g. casă – case "house(s)" vs. lună – luni "moon(s)"; frate – fraţi "brother(s)" vs. carte – cărţi "book(s)" vs. vale – văi "valley(s)".)
In Italian, the situation is somewhere in between Spanish and Romanian. There are no case endings and relatively few classes, as in Spanish, but noun endings are generally formed with vowels instead of /s/, as in Romanian: amico – amici "friend(s) (masc.)", amica – amiche "friend(s) (fem.)"; cane – cani "dog(s)". The masculine plural amici is thought to reflect the Latin nominative plural -ī rather than accusative plural -ōs (Spanish -os); however, the other plurals are thought to stem from special developments of Latin -ās and -ēs.
A different type of noun inflection survived into the medieval period in a number of western Romance languages (Old French, Old Occitan, and the older forms of a number of Rhaeto-Romance languages). This inflection distinguished nominative from oblique, grouping the accusative case with the oblique, rather than with the nominative as in Romanian.
The oblique case in these languages generally inherits from the Latin accusative; as a result, masculine nouns have distinct endings in the two cases while most feminine nouns do not.
A number of different inflectional classes are still represented at this stage. For example, the difference in the nominative case between masculine li voisins "the neighbor" and li pere "the father", and feminine la riens "the thing" vs. la fame "the woman", faithfully reflects the corresponding Latin inflectional differences (vicīnus vs. pater, fēmina vs. rēs).
A number of synchronically quite irregular differences between nominative and oblique reflect direct inheritances of Latin third-declension nouns with two different stems (one for the nominative singular, one for all other forms), most with of which had a stress shift between nominative and the other forms: li ber – le baron "baron" (barō – barōnem); la suer – la seror "sister" (soror – sorōrem); li prestre – le prevoire "priest" (presbyter – presbyterem); li sire – le seigneur "lord" (senior – seniōrem); li enfes – l'enfant "child" (infāns – infantem).:36–39
A few of these multi-stem nouns derive from Latin forms without stress shift, e.g. li om – le ome "man" (homō – hominem). All of these multi-stem nouns refer to people; other nouns with stress shift in Latin (e.g. amor – amōrem "love") have not survived. Some of the same nouns with multiple stems in Old French or Old Occitan have come down in Italian in the nominative rather than the accusative (e.g. uomo "man" < homō, moglie "wife" < mulier), suggesting that a similar system existed in pre-literary Italian.
The modern situation in Sursilvan (one of the Rhaeto-Romance languages) is unique in that the original nominative/oblique distinction has been reinterpreted as a predicative/attributive distinction::381
As described above, case marking on pronouns is much more extensive than for nouns. Determiners (e.g. words such as "a", "the", "this") are also marked for case in Romanian.
Most Romance languages have the following sets of pronouns and determiners:
Unlike in English, a separate neuter personal pronoun ("it") generally does not exist, but the third-person singular and plural both distinguish masculine from feminine. Also, as described above, case is marked on pronouns even though it is not usually on nouns, similar to English. As in English, there are forms for nominative case (subject pronouns), oblique case (object pronouns), and genitive case (possessive pronouns); in addition, third-person pronouns distinguish accusative and dative. There is also an additional set of possessive determiners, distinct from the genitive case of the personal pronoun; this corresponds to the English difference between "my, your" and "mine, yours".
The Romance languages do not retain the Latin third-person personal pronouns, but have innovated a separate set of third-person pronouns by borrowing the demonstrative ille ("that (over there)"), and creating a separate reinforced demonstrative by attaching a variant of ecce "behold!" (or "here is ...") to the pronoun.
Similarly, in place of the genitive of the Latin pronouns, most Romance languages adopted the reflexive possessive, which then serves indifferently as both reflexive and non-reflexive possessive. Note that the reflexive, and hence the third-person possessive, is unmarked for the gender of the person being referred to. Hence, although gendered possessive forms do exist—e.g. Portuguese seu (masc.) vs. sua (fem.)—these refer to the gender of the object possessed, not the possessor.
The gender of the possessor needs to be made clear by a collocation such as French la voiture à lui/elle, Portuguese o carro dele/dela, literally "the car of him/her". (In spoken Brazilian Portuguese, these collocations are the usual way of expressing the third-person possessive, since the former possessive seu carro now has the meaning "your car".)
The same demonstrative ille is the source of the definite article in most Romance languages (see below), which explains the similarity in form between personal pronoun and definite article. When the two are different, it is usually because of differing degrees of phonological reduction. Generally, the personal pronoun is unreduced (beyond normal sound change), while the article has undergone various degrees of reduction, beginning with loss of one of the two original syllables, e.g. Spanish ella "she" < illa vs. la "the (fem.)" < -la < illa, or masculine el, developed from il- < illud.
Object pronouns in Latin were normal words, but in the Romance languages they have become clitic forms, which must stand adjacent to a verb and merge phonologically with it. Originally, object pronouns could come either before or after the verb; sound change would often produce different forms in these two cases, with numerous additional complications and contracted forms when multiple clitic pronouns cooccurred.
Catalan still largely maintains this system with a highly complex clitic pronoun system. Most languages, however, have simplified this system by undoing some of the clitic mergers and requiring clitics to stand in a particular position relative to the verb (usually after imperatives, before other finite forms, and either before or after non-finite forms depending on the language).
When a pronoun cannot serve as a clitic, a separate disjunctive form is used. These result from dative object pronouns pronounced with stress (which causes them to develop differently from the equivalent unstressed pronouns), or from subject pronouns.
Most Romance languages are null subject languages. The subject pronouns are used only for emphasis and take the stress, and as a result are not clitics. In French, however (as in Friulian and in some Gallo-Italian languages of northern Italy), verbal agreement marking has degraded to the point that subject pronouns have become mandatory, and have turned into clitics. These forms cannot be stressed, so for emphasis the disjunctive pronouns must be used in combination with the clitic subject forms. Friulian and the Gallo-Italian languages have actually gone further than this and merged the subject pronouns onto the verb as a new type of verb agreement marking, which must be present even when there is a subject noun phrase. (Some non-standard varieties of French treat disjunctive pronouns as arguments and clitic pronouns as agreement markers.)
In medieval times, most Romance languages developed a distinction between familiar and polite second-person pronouns (a so-called T-V distinction), similar to the former English distinction between familiar "thou" and polite "you". This distinction was determined by the relationship between the speakers. As in English, this generally developed by appropriating the plural second-person pronoun to serve in addition as a polite singular. French is still at this stage, with familiar singular tu vs. formal or plural vous. In cases like this, the pronoun requires plural agreement in all cases whenever a single affix marks both person and number (as in verb agreement endings and object and possessive pronouns), but singular agreement elsewhere where appropriate (e.g. vous-même "yourself" vs. vous-mêmes "yourselves").
Many languages, however, innovated further in developing an even more polite pronoun, generally composed of some noun phrases (e.g. Portuguese vossa mercê "your mercy", progressively reduced to vossemecê, vosmecê and finally você) and taking third-person singular agreement. A plural equivalent was created at the same time or soon after (Portuguese vossas mercês, reduced to vocês), taking third-person plural agreement. Spanish innovated similarly, with usted(es) from earlier vuestra(s) merced(es).
In Portuguese and Spanish (as in other languages with similar forms), the "extra-polite" forms in time came to be the normal polite forms, and the former polite (or plural) second-person vos was displaced to a familiar form, either becoming a familiar plural (as in European Spanish) or a familiar singular (as in many varieties of Latin American Spanish). In the latter case, it either competes with the original familiar singular tú (as in Guatemala), displaces it entirely (as in Argentina), or is itself displaced (as in Mexico, except in Chiapas). In the Spanish of the Americas, the gap created by the loss of familiar plural vos was filled by originally polite ustedes, with the result that there is no familiar/polite distinction in the plural, just as in the original tú/vos system.
A similar path was followed by Italian and Romanian. Romanian uses dumneavoastră "your lordship", while Italian the former polite phrase sua eccellenza "your excellency" has simply been supplanted by the corresponding pronoun Ella or Lei (literally "she", but capitalized when meaning "you"). As in European Spanish, the original second-person plural voi serves as familiar plural. (In Italy, during fascist times leading up to World War II, voi was resurrected as a polite singular, and discarded again afterwards, although it remains in some southern dialects.)
Portuguese innovated again in developing a new extra-polite pronoun o senhor "the sir", which in turn downgraded você. Hence, modern European Portuguese has a three-way distinction between "familiar" tu, "equalizing" você and "polite" o senhor. (The original second-person plural vós was discarded centuries ago in speech, and is used today only in translations of the Bible, where tu and vós serve as universal singular and plural pronouns, respectively.)
Brazilian Portuguese, however, has diverged from this system, and most dialects simply use você (and plural vocês) as a general-purpose second-person pronoun, combined with te (from tu) as the clitic object pronoun. The form o senhor (and feminine a senhora) is sometimes used in speech, but only in situations where an English speaker would say "sir" or "ma'am". The result is that second-person verb forms have disappeared, and the whole pronoun system has been radically realigned. However that is the case only in the spoken language of central and northern Brazil, with the northeastern and southern areas of the country still largely preserving the second-person verb form and the "tu" and "você" distinction.
Catalan still retains the plural form vós for formal distinction (similarly to French) but it is falling out of use, and nowadays is usually seen in extremely formal circumstances or in writing. Instead, vostè (Central) or vosté (Valencian) is normally used orally, which functions just like Spanish and Portuguese usted/você.
Latin had no articles as such. The closest definite article was the non-specific demonstrative is, ea, id meaning approximately "this/that/the". The closest indefinite articles were the indefinite determiners aliquī, aliqua, aliquod "some (non-specific)" and certus "a certain".
Romance languages have both indefinite and definite articles, but none of the above words form the basis for either of these. Usually the definite article is derived from the Latin demonstrative ille ("that"), but some languages (e.g. Sardinian, Old Occitan, and Balearic Catalan) have forms from ipse (emphatic, as in "I myself"). The indefinite article everywhere is derived from the number ūnus ("one").
Some languages, e.g. French and Italian, have a partitive article that approximately translates as "some". This is used either with mass nouns or with plural nouns—both cases where the indefinite article cannot occur. A partitive article is used (and in French, required) whenever a bare noun refers to specific (but unspecified or unknown) quantity of the noun, but not when a bare noun refers to a class in general. For example, the partitive would be used in both of the following sentences:
The sentence "Men arrived today", however, (presumably) means "some specific men arrived today" rather than "men, as a general class, arrived today" (which would mean that there were no men before today). On the other hand, "I hate men" does mean "I hate men, as a general class" rather than "I hate some specific men".
As in many other cases, French has developed the farthest from Latin in its use of articles. In French, nearly all nouns, singular and plural, must be accompanied by an article (either indefinite, definite, or partitive) or demonstrative pronoun.
Due to pervasive sound changes in French, most nouns are pronounced identically in the singular and plural, and there is often heavy homophony between nouns and identically pronounced words of other classes. For example, all of the following are pronounced /sɛ̃/: sain "healthy"; saint "saint, holy"; sein "breast"; ceins "(you) tie around, gird"; ceint "(he) ties around, girds"; ceint "tied around, girded"; and the equivalent noun and adjective plural forms sains, saints, seins, ceints. The article helps identify the noun forms saint or sein, and distinguish singular from plural; likewise, the mandatory subject of verbs helps identify the verb ceint. In more conservative Romance languages, neither articles nor subject pronouns are necessary, since all of the above words are pronounced differently. In Italian, for example, the equivalents are sano, santo, seno, cingi, cinge, cinto, sani, santi, seni, cinti, where all vowels and consonants are pronounced as written, and ⟨s⟩ /s/ and ⟨c⟩ /t͡ʃ/ are clearly distinct from each other.
Latin, at least originally, had a three-way distinction among demonstrative pronouns distinguished by distal value: hic 'this', iste 'that (near you)', ille 'that (over there)', similar to the distinction that used to exist in English as "this" vs. "that" vs. "yon(der)". In urban Latin of Rome, iste came to have a specifically derogatory meaning, but this innovation apparently did not reach the provinces and is not reflected in the modern Romance languages. A number of these languages still have such a three-way distinction, although hic has been lost and the other pronouns have shifted somewhat in meaning. For example, Spanish has este "this" vs. ese "that (near you)" vs. aquel (fem. aquella) "that (over yonder)". The Spanish pronouns derive, respectively, from Latin iste ipse accu-ille, where accu- is an emphatic prefix derived from eccum "behold (it!)" (still vigorous in Italy as Ecco! 'Behold!'), possibly with influence from atque "and".
Reinforced demonstratives such as accu-ille arose as ille came to be used as an article as well as a demonstrative. Such forms were often created even when not strictly needed to distinguish otherwise ambiguous forms. Italian, for example, has both questo "this" (eccu-istum) and quello "that" (eccu-illum), in addition to dialectal codesto "that (near you)" (*eccu-tē-istum). French generally prefers forms derived from bare ecce "behold", as in the pronoun ce "this one/that one" (earlier ço, from ecce-hoc; cf. Italian ciò 'that') and the determiner ce/cet "this/that" (earlier cest, from ecce-istum).
Reinforced forms are likewise common in locative adverbs (words such as English here and there), based on related Latin forms such as hic "this" vs. hīc "here", hāc "this way", and ille "that" vs. illīc "there", illāc "that way". Here again French prefers bare ecce while Spanish and Italian prefer eccum (French ici "here" vs. Spanish aquí, Italian qui). In western languages such as Spanish, Portuguese and Catalan, doublets and triplets arose such as Portuguese aqui, acá, cá "(to) here" (accu-hīc, accu-hāc, eccu-hāc). From these, a prefix a- was extracted, from which forms like aí "there (near you)" (a-(i)bi) and ali "there (over yonder)" (a-(i)llīc) were created; compare Catalan neuter pronouns açò (acce-hoc) "this", això (a-(i)psum-hoc) "that (near you)", allò (a-(i)llum-hoc) "that (yonder)".
Subsequent changes often reduced the number of demonstrative distinctions. Standard Italian, for example, has only a two-way distinction "this" vs. "that", as in English, with second-person and third-person demonstratives combined. In Catalan, however, a former three-way distinction aquest, aqueix, aquell has been reduced differently, with first-person and second-person demonstratives combined. Hence aquest means either "this" or "that (near you)"; on the phone, aquest is used to refer both to speaker and addressee.
Old French had a similar distinction to Italian (cist/cest vs. cil/cel), both of which could function as either adjectives or pronouns. Modern French, however, has no distinction between "this" and "that": ce/cet, cette < cest, ceste is only an adjective, and celui, celle < cel lui, celle is only a pronoun, and both forms indifferently mean either "this" or "that". (The distinction between "this" and "that" can be made, if necessary, by adding the suffixes -ci "here" or -là "there", e.g. cette femme-ci "this woman" vs. cette femme-là "that woman", but this is rarely done except when specifically necessary to distinguish two entities from each other.)
Several tenses and aspects, especially of the indicative mood, have been preserved with little change in most languages, as shown in the following table for the Latin verb dīcere (to say), and its descendants.
The main tense and mood distinctions that were made in classical Latin are generally still present in the modern Romance languages, though many are now expressed through compound rather than simple verbs. The passive voice, which was mostly synthetic in classical Latin, has been completely replaced with compound forms.
For a more detailed illustration of how the verbs have changed with respect to classical Latin, see Romance verbs.
Note that in Catalan, the synthetic preterite is predominantly a literary tense, except in Valencian; but an analytic preterite (formed using an auxiliary vadō, which in other languages signals the future) persists in speech, with the same meaning. In Portuguese, a morphological present perfect does exist but has a different meaning (closer to "I have been doing").
The following are common features of the Romance languages (inherited from Vulgar Latin) that are different from Classical Latin:
Romance languages have borrowed heavily, though mostly from other Romance languages. However, some, such as Spanish, Portuguese, Romanian, and French, have borrowed heavily from other language groups. Vulgar Latin borrowed first from indigenous languages of the Roman empire, and during the Germanic folk movements, from Germanic languages, especially Gothic; for Eastern Romance languages, during Bulgarian Empires, from Slavic languages, especially Bulgarian. Notable examples are *blancus "white", replacing native albus (but Romansh alv, Dalmatian jualb, Romanian alb); *guerra "war", replacing native bellum; and the words for the cardinal directions, where cognates of English "north", "south", "east" and "west" replaced the native words septentriō, merīdiēs (also "noon; midday nap"; cf. Romanian meriză), oriens, and occidens. (See History of French – The Franks.) Some Celtic words were incorporated into the core vocabulary, partly for words with no Latin equivalent (betulla "birch", camisia "shirt", cerevisia "beer"), but in some cases replacing Latin vocabulary (gladius "sword", replacing ensis; cambiāre "to exchange", replacing mūtāre except in Romanian and Portuguese; carrus "cart", replacing currus; pettia "piece", largely displacing pars (later resurrected) and eliminating frustum). Many Greek loans also entered the lexicon, e.g. spatha "sword" (Greek: σπάθη spáthē, replacing gladius which shifted to "iris", cf. French épée, Spanish espada, Italian spada and Romanian spată); cara "face" (Greek: κάρα kára, partly replacing faciēs); colpe "blow" (Greek: κόλαφος kólaphos, replacing ictus, cf. Spanish golpe, French coup); cata "each" (Greek: κατά katá, replacing quisque); common suffixes *-ijāre/-izāre (Greek: -ίζειν -izein, French oyer/-iser, Spanish -ear/-izar, Italian -eggiare/-izzare, etc.), -ista (Greek: -ιστής -istes).
Many basic nouns and verbs, especially those that were short or had irregular morphology, were replaced by longer derived forms with regular morphology. Nouns, and sometimes adjectives, were often replaced by diminutives, e.g. auris "ear" > auricula (orig. "outer ear") > oricla (Sardinian origra, Italian orecchia/o, Portuguese orelha, etc.); avis "bird" > avicellus (orig. "chick, nestling") > aucellu (Occitan aucèl, Friulian ucel, Neapolitan auciello, etc.); caput "head" > capitium (Portuguese cabeça, Spanish cabeza, French chevet "headboard"; but reflexes of caput were retained also, sometimes without change of meaning, as in Italian capo "head", alongside testa); vetus "old" > vetulus > veclus (Dalmatian vieklo, Italian vecchio, Portuguese velho, etc.). Sometimes augmentative constructions were used instead: piscis "fish" > Old French peis > peisson (orig. "big fish") > French poisson. Verbs were often replaced by frequentative constructions: canere "to sing" > cantāre; iacere "to throw" > iactāre > *iectāre (Italian gettare, Portuguese jeitar, Spanish echar, etc.); iuvāre > adiūtāre (Italian aiutare, Spanish ayudar, French aider, etc., meaning "help", alongside e.g. iuvāre > Italian giovare "to be of use"); vēnārī "hunt" (Romanian vâna, Aromanian avinari) > replaced by *captiāre "to hunt", frequentative of capere "to seize" (Italian cacciare, Portuguese caçar, Romansh catschar, French chasser, etc.).
Many Classical Latin words became archaic or poetic and were replaced by more colloquial terms: equus "horse" > caballus (orig. "nag") (but equa "mare" remains, cf. Spanish yegua, Portuguese égua, Sardinian ebba, Romanian iapă); domus "house" > casa (orig. "hut"); ignis "fire" > focus (orig. "hearth"); strāta "street" > rūga (orig. "furrow") or callis (orig. "footpath") (but strāta is continued in Italian strada). In some cases, terms from common occupations became generalized: invenīre "to find" replaced by afflāre (orig. "to sniff out", in hunting, cf. Spanish hallar, Portuguese achar, Romansh dial. anflar, Southern Italian asciare, acchiare, Romanian afla 'to find out'); advenīre "to arrive" gave way to plicāre (orig. "to fold (sails; tents)", cf. Spanish llegar, Portuguese chegar; Romanian pleca), elsewhere arripāre (orig. "to harbor at a riverbank", cf. Italian arrivare, French arriver) (advenīre is continued with the meaning "to achieve, manage to do" as in Middle French aveindre, or "to happen" in Italian avvenire) . The same thing sometimes happened to religious terms, due to the pervasive influence of Christianity: loquī "to speak" succumbed to parabolāre (orig. "to tell parables", cf. Occitan parlar, French parler, Italian parlare) or fabulārī ~ fābellāre (orig. "to tell stories", cf. Spanish hablar, Dalmatian favlur, Sardinian faeddare), based on Jesus' way of speaking in parables.
Many prepositions were used as verbal particles to make new roots and verb stems, e.g. Italian estrarre, Aromanian astragu, astradziri "to extract" from Latin ex- "out of" and trahere "to pull" (Italian trarre "draw, pull", Aromanian tragu, tradziri), or to augment already existing words, e.g. French coudre, Italian cucire, Portuguese coser "to sew", from cōnsuere "to sew up", from suere "to sew", with total loss of the bare stem. Many prepositions and commonly became compounded, e.g. de ex > French dès "as of", ab ante > Italian avanti "forward". Some words derived from phrases, e.g. Portuguese agora, Spanish ahora "now" < hāc hōrā "at this hour"; French avec "with" (prep.) < Old French avuec (adv.) < apud hoc "with that"; Spanish tamaño, Portuguese tamanho "size" < tam magnum "so big"; Italian codesto "this, that" (near you) < Old Italian cotevesto < eccum tibi istum approx. "here's that thing of yours"; Portuguese você "you" < vosmecê < vossemecê < Galician-Portuguese vossa mercee "your mercy".
A number of common Latin words that have disappeared in many or most Romance languages have survived either in the periphery or in remote corners (especially Sardinia and Romania), or as secondary terms, sometimes differing in meaning. For example, Latin caseum "cheese" in the periphery (Portuguese queijo, Spanish queso, Romansh caschiel, Sardinian càsu, Romanian caş), but in the central areas has been replaced by formāticum, originally "moulded (cheese)" (French fromage, Occitan/Catalan formatge, Italian formaggio, with, however, cacio also available in much of Italy; similarly (com)edere "to eat (up)", which survives as Spanish/Portuguese comer but elsewhere is replaced by mandūcāre, originally "to chew" (French manger, Sardinian mandicare alongside pappare, Romanian mânca(re)). In some cases, one language happens to preserve a word displaced elsewhere, e.g. Italian ogni "each, every" < omnes, displaced elsewhere by tōtum, originally "whole" or by a reflex of Greek κατά (e.g. Italian ognuno, Catalan tothom "everyone"; Italian ogni giorno, Spanish cada día "every day"); Friulian vaî "to cry" < flere "to weep"; Serbo-Croatian (Dubrovnik) otijemna "sail pole" < Dalmatian < antenna "yardarm". Sardinian in particular preserves many words entirely lost elsewhere, e.g. eja "yes" < etiam "also/yes/indeed", emmo "yes" < immo "rather/yes/no", mannu "big" < magnus, nàrrere "to say" < narrāre "to tell", and domo "house" < (abl.) domō "at home". Sardinian preserves some words that were already archaic in Classical Latin, e.g. àchina "grape" < acinam, while Sicily and Calabria typically have forms with initial /r/: ràcina.
During the Middle Ages, scores of words were borrowed directly from Classical Latin (so-called Latinisms), either in their original form (learned loans) or in a somewhat nativized form (semi-learned loans). These resulted in many doublets—pairs of inherited and learned words—such as those in the table below:
Sometimes triplets arise: Latin articulus "joint" > Portuguese artículo "joint, knuckle" (learned), artigo "article" (semi-learned), artelho "ankle" (inherited; archaic and dialectal). In many cases, the learned word simply displaced the original popular word: e.g. Spanish crudo "crude, raw" (Old Spanish cruo); French légume "vegetable" (Old French leüm); Portuguese flor "flower" (Galician-Portuguese chor). The learned loan always sounds (and, in writing, looks) more like the original than the inherited word does, because regular sound change has been bypassed; likewise, the learned word usually has a meaning closer to that of the original. In French, the stress of the modern form of the learned loan may be on the "wrong" syllable vis-à-vis Latin, whereas the stress of the inherited word always corresponds to the Latin stress: e.g. Latin vipera (stress on /i/) vs. French vipère, learned loan, and guivre/vouivre, inherited.
Borrowing from Classical Latin has produced a large number of suffix doublets. Examples from Spanish (learned form first): -ción vs. -zon; -cia vs. -za; -ificar vs. -iguar; -izar vs. -ear; -mento vs. -miento; -tud (< nominative -tūdō) vs. -dumbre (< accusative -tūdine); -ículo vs. -ejo; etc. Similar examples can be found in all the other Romance languages.
This borrowing also introduced large numbers of classical prefixes in their original form (dis-, ex-, post-, trans-) and reinforced many others (re-, popular Spanish/Portuguese des- < dis-, popular French dé- < dis-, popular Italian s- < ex-). Many Greek prefixes and suffixes (hellenisms) also found their way into the lexicon: tele-, poli-/poly-, meta-, pseudo-, -scope/scopo, -logie/logia/logía, etc.
Significant sound changes affected the consonants of the Romance languages.
Many final consonants were rare, occurring only in certain prepositions (e.g. ad "towards", apud "at, near (a person)"), conjunctions (sed "but"), demonstratives (e.g. illud "that (over there)", hoc "this"), and nominative singular noun forms, especially of neuter nouns (e.g. lac "milk", mel "honey", cor "heart"). Many of these prepositions and conjunctions were replaced by others, while the nouns were regularized into forms based on their oblique stems that avoided the final consonants (e.g. *lacte, *mele, *core).
Final -m was dropped in Vulgar Latin. Even in Classical Latin, final -am, -em, -um (inflectional suffixes of the accusative case) were often elided in poetic meter, suggesting the m was weakly pronounced, probably marking the nasalisation of the vowel before it. This nasal vowel lost its nasalization in the Romance languages except in monosyllables, where it became /n/ e.g. Spanish quien < quem "whom", French rien "anything" < rem "thing"; note especially French and Catalan mon < meum "my (m.sg.)" pronounced as one syllable (/meu̯m/ > */meu̯n/, /mun/) but Spanish mío and Portuguese and Catalan meu < meum pronounced as two (/ˈme.um/ > */ˈme.o/).
As a result, only the following final consonants occurred in Vulgar Latin:
Final -t was eventually dropped in many languages, although this often occurred several centuries after the Vulgar Latin period. For example, the reflex of -t was dropped in Old French and Old Spanish only around 1100. In Old French, this occurred only when a vowel still preceded the t (generally /ə/ < Latin a). Hence amat "he loves" > Old French aime but venit "he comes" > Old French vient: the /t/ was never dropped and survives into Modern French in liaison, e.g. vient-il? "is he coming?" /vjɛ̃ti(l)/ (the corresponding /t/ in aime-t-il? is analogical, not inherited). Old French also kept the third-person plural ending -nt intact.
In Italo-Romance and the Eastern Romance languages, eventually all final consonants were either dropped or protected by an epenthetic vowel, except in clitic forms (e.g. prepositions con, per). Modern Standard Italian still has almost no consonant-final words, although Romanian has resurfaced them through later loss of final /u/ and /i/. For example, amās "you love" > ame > Italian ami; amant "they love" > *aman > Ital. amano. On the evidence of "sloppily written" Lombardic language documents, however, the loss of final /s/ in Italy did not occur until the 7th or 8th century, after the Vulgar Latin period, and the presence of many former final consonants is betrayed by the syntactic gemination (raddoppiamento sintattico) that they trigger. It is also thought that after a long vowel /s/ became /j/ rather than simply disappearing: nōs > noi "we", se(d)ēs > sei "you are", crās > crai "tomorrow" (southern Italian). In unstressed syllables, the resulting diphthongs were simplified: canēs > /ˈkanej/ > cani "dogs"; amīcās > /aˈmikaj/ > amiche /aˈmike/ "(female) friends", where nominative amīcae should produce **amice rather than amiche (note masculine amīcī > amici not **amichi).
Central Western Romance languages eventually regained a large number of final consonants through the general loss of final /e/ and /o/, e.g. Catalan llet "milk" < lactem, foc "fire" < focum, peix "fish" < piscem. In French, most of these secondary final consonants (as well as primary ones) were lost before around 1700, but tertiary final consonants later arose through the loss of /ə/ < -a. Hence masculine frīgidum "cold" > Old French freit /frwεt/ > froid /fʁwa/, feminine frigidam > Old French freide /frwεdə/ > froide /fʁwad/.
Palatalization was one of the most important processes affecting consonants in Vulgar Latin. This eventually resulted in a whole series of "palatal" and postalveolar consonants in most Romance languages, e.g. Italian /ʃ/, /ʒ/, /tʃ/, /dʒ/, /ts/, /dz/, /ɲ/, /ʎ/.
Note how the environments become progressively less "palatal", and the languages affected become progressively fewer.
The outcomes of palatalization depended on the historical stage, the consonants involved, and the languages involved. The primary division is between the Western Romance languages, with /ts/ resulting from palatalization of /k/, and the remaining languages (Italo-Dalmatian and Eastern Romance), with /tʃ/ resulting. It is often suggested that /tʃ/ was the original result in all languages, with /tʃ/ > /ts/ a later innovation in the Western Romance languages. Evidence of this is the fact that Italian has both /ttʃ/ and /tts/ as outcomes of palatalization in different environments, while Western Romance has only /(t)ts/. Even more suggestive is the fact that the Mozarabic language in al-Andalus (modern southern Spain) had /tʃ/ as the outcome despite being in the "Western Romance" area and geographically disconnected from the remaining /tʃ/ areas; this suggests that Mozarabic was an outlying "relic" area where the change /tʃ/ > /ts/ failed to reach. (Northern French dialects, such as Norman and Picard, also had /tʃ/, but this may be a secondary development, i.e. due to a later sound change /ts/ > /tʃ/.) Note that /ts, dz, dʒ/ eventually became /s, z, ʒ/ in most Western Romance languages. Thus Latin caelum (sky, heaven), pronounced [ˈkai̯lu(m)] with an initial [k], became Italian cielo [ˈtʃɛlo], Romanian cer [tʃer], Spanish cielo [ˈθjelo]/[ˈsjelo], French ciel [sjɛl], Catalan cel [ˈsɛɫ], and Portuguese céu [ˈsɛw].
This suggests that palatalized /d/ > /dʲ/ > either /j/ or /dz/ depending on location, while palatalized /ɡ/ > /j/; after this, /j/ > /(d)dʒ/ in most areas, but Spanish and Gascon (originating from isolated districts behind the western Pyrenees) were relic areas unaffected by this change.
In French, the outcomes of /k, ɡ/ palatalized by /e, i, j/ and by /a, au/ were different: centum "hundred" > cent /sɑ̃/ but cantum "song" > chant /ʃɑ̃/. French also underwent palatalization of labials before /j/: Vulgar Latin /pj, bj~vj, mj/ > Old French /tʃ, dʒ, ndʒ/ (sēpia "cuttlefish" > seiche, rubeus "red" > rouge, sīmia "monkey" > singe).
The original outcomes of palatalization must have continued to be phonetically palatalized even after they had developed into alveolar/postalveolar/etc. consonants. This is clear from French, where all originally palatalized consonants triggered the development of a following glide /j/ in certain circumstances (most visible in the endings -āre, -ātum/ātam). In some cases this /j/ came from a consonant palatalized by an adjoining consonant after the late loss of a separating vowel. For example, mansiōnātam > /masʲoˈnata/ > masʲˈnada/ > /masʲˈnʲæðə/ > early Old French maisnieḍe /maisˈniɛðə/ "household". Similarly, mediētātem > /mejeˈtate/ > /mejˈtade/ > /mejˈtæðe/ > early Old French meitieḍ /mejˈtʲɛθ/ > modern French moitié /mwaˈtje/ "half". In both cases, phonetic palatalization must have remained in primitive Old French at least through the time when unstressed intertonic vowels were lost (?c.8th century), well after the fragmentation of the Romance languages.
The effect of palatalization is indicated in the writing systems of almost all Romance languages, where the letters have the "hard" pronunciation [k, ɡ] in most situations, but a "soft" pronunciation (e.g. French/Portuguese [s, ʒ], Italian/Romanian [tʃ, dʒ]) before ⟨e, i, y⟩. (This orthographic trait has passed into Modern English through Norman French-speaking scribes writing Middle English; this replaced the earlier system of Old English, which had developed its own hard-soft distinction with the soft ⟨c, g⟩ representing [tʃ, j~dʒ].) This has the effect of keeping the modern spelling similar to the original Latin spelling, but complicates the relationship between sound and letter. In particular, the hard sounds must be written differently before ⟨e, i, y⟩ (e.g. Italian ⟨ch, gh⟩, Portuguese ⟨qu, gu⟩), and likewise for the soft sounds when not before these letters (e.g. Italian ⟨ci, gi⟩, Portuguese ⟨ç, j⟩). Furthermore, in Spanish, Catalan, Occitan and Brazilian Portuguese, the use of digraphs containing ⟨u⟩ to signal the hard pronunciation before ⟨e, i, y⟩ means that a different spelling is also needed to signal the sounds /kw, ɡw/ before these vowels (Spanish ⟨cu, gü⟩, Catalan, Occitan and Brazilian Portuguese ⟨qü, gü⟩). This produces a number of orthographic alternations in verbs whose pronunciation is entirely regular. The following are examples of corresponding first-person plural indicative and subjunctive in a number of regular Portuguese verbs: marcamos, marquemos "we mark"; caçamos, cacemos "we hunt"; chegamos, cheguemos "we arrive"; averiguamos, averigüemos "we verify"; adequamos, adeqüemos "we adapt"; oferecemos, ofereçamos "we offer"; dirigimos, dirijamos "we drive" erguemos, ergamos "we raise"; delinquimos, delincamos "we commit a crime". In the case of Italian, the convention of digraphs <ch> and <gh> to represent /k/ and /g/ before written <e, i> results in similar orthographic alternations, such as dimentico 'I forget', dimentichi 'you forget', baco 'worm', bachi 'worms' with [k] or pago 'I pay', paghi 'you pay' and lago 'lake', laghi 'lakes' with [g]. The use in Italian of <ci> and <gi> to represent /tʃ/ or /dʒ/ before vowels written <a,o,u> neatly distinguishes dico 'I say' with /k/ from dici 'you say' with /tʃ/ or ghiro 'dormouse' /g/ and giro 'turn, revolution' /dʒ/, but with orthographic <ci> and <gi> also representing the sequence of /tʃ/ or /dʒ/ and the actual vowel /i/ (/ditʃi/ dici, /dʒiro/ giro), and no generally observed convention of indicating stress position, the status of i when followed by another vowel in spelling can be unrecognizable. For example, the written forms offer no indication that <cia> in camicia 'shirt' represents a single unstressed syllable /tʃa/ with no /i/ at any level (/kaˈmitʃa/ → [kaˈmiːtʃa] ~ [kaˈmiːʃa]), but that underlying the same spelling <cia> in farmacia 'pharmacy' is a bisyllabic sequence consisting of the stressed syllable /tʃi/ and syllabic /a/ (/farmaˈtʃia/ → [farmaˈtʃiːa] ~ [farmaˈʃiːa]).
The voiced labial consonants /b/ and /w/ (represented by ⟨b⟩ and ⟨v⟩, respectively) both developed a fricative [β] as an intervocalic allophone. This is clear from the orthography; in medieval times, the spelling of a consonantal ⟨v⟩ is often used for what had been a ⟨b⟩ in Classical Latin, or the two spellings were used interchangeably. In many Romance languages (Italian, French, Portuguese, Romanian, etc.), this fricative later developed into a /v/; but in others (Spanish, Galician, some Catalan and Occitan dialects, etc.) reflexes of /b/ and /w/ simply merged into a single phoneme.
Several other consonants were "softened" in intervocalic position in Western Romance (Spanish, Portuguese, French, Northern Italian), but normally not phonemically in the rest of Italy (except some cases of "elegant" or Ecclesiastical words), nor apparently at all in Romanian. The dividing line between the two sets of dialects is called the La Spezia–Rimini Line and is one of the most important isoglosses of the Romance dialects. The changes (instances of diachronic lenition resulting in phonological restructuring) are as follows:
Single voiceless plosives became voiced: -p-, -t-, -c- > -b-, -d-, -g-. Subsequently, in some languages they were further weakened, either becoming fricatives or approximants, [β̞], [ð̞], [ɣ˕] (as in Spanish) or disappearing entirely (as /t/ and /k/, but not /p/, in French). The following example shows progressive weakening of original /t/: e.g. vītam > Italian vita [ˈvita], Portuguese vida [ˈvidɐ] (European Portuguese [ˈviðɐ]), Spanish vida [ˈbiða] (Southern Peninsular Spanish [ˈbia]), and French vie [vi]. Some scholars once speculated that these sound changes may be due in part to the influence of Continental Celtic languages, but scholarship of the past few decades challenges that hypothesis.
Consonant length is no longer phonemically distinctive in most Romance languages. However some languages of Italy (Italian, Sardinian, Sicilian, and numerous other varieties of central and southern Italy) do have long consonants like /ɡɡ/, /dd/, /bb/, /kk/, /tt/, /pp/, /ll/, /mm/, /nn/, /ss/, /rr/, etc., where the doubling indicates either actual length or, in the case of plosives and affricates, a short hold before the consonant is released, in many cases with distinctive lexical value: e.g. note /ˈnɔ.te/ (notes) vs. notte /ˈnɔt.te/ (night), cade /ˈka.de/ (s/he, it falls) vs. cadde /ˈkad.de/ (s/he, it fell), caro /ˈka.ro/ (dear, expensive) vs. carro /ˈkar.ro/ (cart). They may even occur at the beginning of words in Romanesco, Neapolitan, Sicilian and other southern varieties, and are occasionally indicated in writing, e.g. Sicilian cchiù (more), and ccà (here). In general, the consonants /b/, /ts/, and /dz/ are long at the start of a word, while the archiphoneme |R|[dubious ] is realised as a trill /r/ in the same position. In much of central and southern Italy, the affricates /t͡ʃ/ and /d͡ʒ/ weaken synchronically to fricative [ʃ] and [ʒ] between vowels, while their geminate congeners do not, e.g. cacio /ˈka.t͡ʃo/ → [ˈkaːʃo] (cheese) vs. caccio /ˈkat.t͡ʃo/ → [ˈkat.t͡ʃo] (I chase).
A few languages have regained secondary geminate consonants. The double consonants of Piedmontese exist only after stressed /ə/, written ë, and are not etymological: vëdde (Latin vidēre, to see), sëcca (Latin sicca, dry, feminine of sech). In standard Catalan and Occitan, there exists a geminate sound /lː/ written ŀl (Catalan) or ll (Occitan), but it is usually pronounced as a simple sound in colloquial (and even some formal) speech in both languages.
In Late Latin a prosthetic vowel /i/ (lowered to /e/ in most languages) was inserted at the beginning of any word that began with /s/ (referred to as s impura) and a voiceless consonant (#sC- > isC-):
Prosthetic /i/ ~ /e/ in Romance languages may have been influenced by Continental Celtic languages, although the phenomenon exists or existed in some areas where Celtic was never present (e.g. Sardinia, southern Italy). While Western Romance words undergo prothesis, cognates in Balkan Romance and southern Italo-Romance do not, e.g. Italian scrivere, spada, spirito, Stefano, and stato. In Italian, syllabification rules were preserved instead by vowel-final articles, thus feminine spada as la spada, but instead of rendering the masculine *il spaghetto, lo spaghetto came to be the norm. Though receding at present, Italian once had a prosthetic /i/ if a consonant preceded such clusters, so that 'in Switzerland' was in [i]Svizzera. Some speakers still use the prothetic [i] productively, and it is fossilized in a few set locutions such as in ispecie 'especially' or per iscritto 'in writing' (although in this case its survival may be due partly to the influence of the separate word iscritto < Latin īnscrīptus). The association of /i/ ~ /j/ and /s/ also led to the vocalization of word-final -s in Italian, Romanian, certain Occitan dialects, and the Spanish dialect of Chocó in Colombia.
One profound change that affected Vulgar Latin was the reorganisation of its vowel system. Classical Latin had five short vowels, ă, ĕ, ĭ, ŏ, ŭ, and five long vowels, ā, ē, ī, ō, ū, each of which was an individual phoneme (see the table in the right, for their likely pronunciation in IPA), and four diphthongs, ae, oe, au and eu (five according to some authors, including ui). There were also long and short versions of y, representing the rounded vowel /y(ː)/ in Greek borrowings, which however probably came to be pronounced /i(ː)/ even before Romance vowel changes started.
There is evidence that in the imperial period all the short vowels except a differed by quality as well as by length from their long counterparts. So, for example ē was pronounced close-mid /eː/ while ĕ was pronounced open-mid /ɛ/, and ī was pronounced close /iː/ while ĭ was pronounced near-close /ɪ/.
During the Proto-Romance period, phonemic length distinctions were lost. Vowels came to be automatically pronounced long in stressed, open syllables (i.e. when followed by only one consonant), and pronounced short everywhere else. This situation is still maintained in modern Italian: cade [ˈkaːde] "he falls" vs. cadde [ˈkadde] "he fell".
The Proto-Romance loss of phonemic length originally produced a system with nine different quality distinctions in monophthongs, where only original /ă ā/ had merged. Soon, however, many of these vowels coalesced:
The Proto-Romance allophonic vowel-length system was rephonemicized in the Gallo-Romance languages as a result of the loss of many final vowels. Some northern Italian languages (e.g. Friulan) still maintain this secondary phonemic length, but most languages dropped it by either diphthongizing or shortening the new long vowels.
French phonemicized a third vowel length system around AD 1300 as a result of the sound change /VsC/ > /VhC/ > /VːC/ (where V is any vowel and C any consonant). This vowel length was eventually lost by around AD 1700, but the former long vowels are still marked with a circumflex. A fourth vowel length system, still non-phonemic, has now arisen: All nasal vowels as well as the oral vowels /ɑ o ø/ (which mostly derive from former long vowels) are pronounced long in all stressed closed syllables, and all vowels are pronounced long in syllables closed by the voiced fricatives /v z ʒ ʁ vʁ/. This system in turn has been phonemicized in some non-standard dialects (e.g. Haitian Creole), as a result of the loss of final /ʁ/.
The Latin diphthongs ae and oe, pronounced /ai/ and /oi/ in earlier Latin, were early on monophthongized.
ae became /ɛː/ by the 1st century a.d. at the latest. Although this sound was still distinct from all existing vowels, the neutralization of Latin vowel length eventually caused its merger with /ɛ/ < short e: e.g. caelum "sky" > French ciel, Spanish/Italian cielo, Portuguese céu /sɛw/, with the same vowel as in mele "honey" > French/Spanish miel, Italian miele, Portuguese mel /mɛl/. Some words show an early merger of ae with /eː/, as in praeda "booty" > *prēda /preːda/ > French proie (vs. expected **priée), Italian preda (not **prieda) "prey"; or faenum "hay" > *fēnum [feːnũ] > Spanish heno, French foin (but Italian fieno /fjɛno/).
oe generally merged with /eː/: poenam "punishment" > Romance */pena/ > Spanish/Italian pena, French peine; foedus "ugly" > Romance */fedo/ > Spanish feo, Portuguese feio. There are relatively few such outcomes, since oe was rare in Classical Latin (most original instances had become Classical ū, as in Old Latin oinos "one" > Classical ūnus) and so oe was mostly limited to Greek loanwords, which were typically learned (high-register) terms.
au merged with ō /oː/ in the popular speech of Rome already by the 1st century b.c. A number of authors remarked on this explicitly, e.g. Cicero's taunt that the populist politician Publius Clodius Pulcher had changed his name from Claudius to ingratiate himself with the masses. This change never penetrated far from Rome, however, and the pronunciation /au/ was maintained for centuries in the vast majority of Latin-speaking areas, although it eventually developed into some variety of o in many languages. For example, Italian and French have /ɔ/ as the usual reflex, but this post-dates diphthongization of /ɔ/ and the French-specific palatalization /ka/ > /tʃa/ (hence causa > French chose, Italian cosa /kɔza/ not **cuosa). Spanish has /o/, but Portuguese spelling maintains ⟨ou⟩, which has developed to /o/ (and still remains as /ou/ in some dialects, and /oi/ in others). Occitan, Romanian, southern Italian languages, and many other minority Romance languages still have /au/. A few common words, however, show an early merger with ō /oː/, evidently reflecting a generalization of the popular Roman pronunciation: e.g. French queue, Italian coda /koda/, Occitan co(d)a, Romanian coadă (all meaning "tail") must all derive from cōda rather than Classical cauda (but notice Portuguese cauda). Similarly, Spanish oreja, Portuguese orelha, French oreille, Romanian ureche, and Sardinian olícra, orícla "ear" must derive from ōric(u)la rather than Classical auris (Occitan aurelha was probably influenced by the unrelated ausir < audīre "to hear"), and the form oricla is in fact reflected in the Appendix Probi.
An early process that operated in all Romance languages to varying degrees was metaphony (vowel mutation), conceptually similar to the umlaut process so characteristic of the Germanic languages. Depending on the language, certain stressed vowels were raised (or sometimes diphthongized) either by a final /i/ or /u/ or by a directly following /j/. Metaphony is most extensive in the Italo-Romance languages, and applies to nearly all languages in Italy; however, it is absent from Tuscan, and hence from standard Italian. In many languages affected by metaphony, a distinction exists between final /u/ (from most cases of Latin -um) and final /o/ (from Latin -ō, -ud and some cases of -um, esp. masculine "mass" nouns), and only the former triggers metaphony.
A number of languages diphthongized some of the free vowels, especially the open-mid vowels /ɛ ɔ/:
These diphthongizations had the effect of reducing or eliminating the distinctions between open-mid and close-mid vowels in many languages. In Spanish and Romanian, all open-mid vowels were diphthongized, and the distinction disappeared entirely. Portuguese is the most conservative in this respect, keeping the seven-vowel system more or less unchanged (but with changes in particular circumstances, e.g. due to metaphony). Other than before palatalized consonants, Catalan keeps /ɔ o/ intact, but /ɛ e/ split in a complex fashion into /ɛ e ə/ and then coalesced again in the standard dialect (Eastern Catalan) in such a way that most original /ɛ e/ have reversed their quality to become /e ɛ/.
In French and Italian, the distinction between open-mid and close-mid vowels occurred only in closed syllables. Standard Italian more or less maintains this. In French, /e/ and /ɛ/ merged by the twelfth century or so, and the distinction between /ɔ/ and /o/ was eliminated without merging by the sound changes /u/ > /y/, /o/ > /u/. Generally this led to a situation where both [e,o] and [ɛ,ɔ] occur allophonically, with the close-mid vowels in open syllables and the open-mid vowels in closed syllables. This is still the situation in modern Spanish, for example. In French, however, both [e/ɛ] and [o/ɔ] were partly rephonemicized: Both /e/ and /ɛ/ occur in open syllables as a result of /aj/ > /ɛ/, and both /o/ and /ɔ/ occur in closed syllables as a result of /al/ > /au/ > /o/.
Old French also had numerous falling diphthongs resulting from diphthongization before palatal consonants or from a fronted /j/ originally following palatal consonants in Proto-Romance or later: e.g. pācem /patsʲe/ "peace" > PWR */padzʲe/ (lenition) > OF paiz /pajts/; *punctum "point" > Gallo-Romance */ponʲto/ > */pojɲto/ (fronting) > OF point /põjnt/. During the Old French period, preconsonantal /l/ [ɫ] vocalized to /w/, producing many new falling diphthongs: e.g. dulcem "sweet" > PWR */doltsʲe/ > OF dolz /duɫts/ > douz /duts/; fallet "fails, is deficient" > OF falt > faut "is needed"; bellus "beautiful" > OF bels [bɛɫs] > beaus [bɛaws]. By the end of the Middle French period, all falling diphthongs either monophthongized or switched to rising diphthongs: proto-OF /aj ɛj jɛj ej jej wɔj oj uj al ɛl el il ɔl ol ul/ > early OF /aj ɛj i ej yj oj yj aw ɛaw ew i ɔw ow y/ > modern spelling ⟨ai ei i oi ui oi ui au eau eu i ou ou u⟩ > mod. French /ɛ ɛ i wa ɥi wa ɥi o o ø i u u y/.
In both French and Portuguese, nasal vowels eventually developed from sequences of a vowel followed by a nasal consonant (/m/ or /n/). Originally, all vowels in both languages were nasalized before any nasal consonants, and nasal consonants not immediately followed by a vowel were eventually dropped. In French, nasal vowels before remaining nasal consonants were subsequently denasalized, but not before causing the vowels to lower somewhat, e.g. dōnat "he gives" > OF dune /dunə/ > donne /dɔn/, fēminam > femme /fam/. Other vowels remained diphthongized, and were dramatically lowered: fīnem "end" > fin /fɛ̃/ (often pronounced [fæ̃]); linguam "tongue" > langue /lɑ̃ɡ/; ūnum "one" > un /œ̃/, /ɛ̃/.
In Portuguese, /n/ between vowels was dropped, and the resulting hiatus eliminated through vowel contraction of various sorts, often producing diphthongs: manum, *manōs > PWR *manu, ˈmanos "hand(s)" > mão, mãos /mɐ̃w̃, mɐ̃w̃s/; canem, canēs "dog(s)" > PWR *kane, ˈkanes > *can, ˈcanes > cão, cães /kɐ̃w̃, kɐ̃j̃s/; ratiōnem, ratiōnēs "reason(s)" > PWR *raˈdʲzʲone, raˈdʲzʲones > *raˈdzon, raˈdzones > razão, razões /χaˈzɐ̃w̃, χaˈzõj̃s/ (Brazil), /ʁaˈzɐ̃ũ, ʁɐˈzõj̃ʃ/ (Portugal). Sometimes the nasalization was eliminated: lūna "moon" > Galician-Portuguese lũa > lua; vēna "vein" > Galician-Portuguese vẽa > veia. Nasal vowels that remained actually tend to be raised (rather than lowered, as in French): fīnem "end" > fim /fĩ/; centum "hundred" > PWR tʲsʲɛnto > cento /ˈsẽtu/; pontem "bridge" > PWR pɔnte > ponte /ˈpõtʃi/ (Brazil), /ˈpõtɨ/ (Portugal). In Portugal, vowels before a nasal consonant have become denasalized, but in Brazil they remain heavily nasalized.
Characteristic of the Gallo-Romance languages and Rhaeto-Romance languages are the front rounded vowels /y ø œ/. All of these languages show an unconditional change /u/ > /y/, e.g. lūnam > French lune /lyn/, Occitan /ˈlyno/. Many of the languages in Switzerland and Italy show the further change /y/ > /i/. Also very common is some variation of the French development /ɔː oː/ (lengthened in open syllables) > /we ew/ > /œ œ/, with mid back vowels diphthongizing in some circumstances and then re-monophthongizing into mid-front rounded vowels. (French has both /ø/ and /œ/, with /ø/ developing from /œ/ in certain circumstances.)
There was more variability in the result of the unstressed vowels. Originally in Proto-Romance, the same nine vowels developed in unstressed as stressed syllables, and in Sardinian, they coalesced into the same five vowels in the same way.
In Italo-Western Romance, however, vowels in unstressed syllables were significantly different from stressed vowels, with yet a third outcome for final unstressed syllables. In non-final unstressed syllables, the seven-vowel system of stressed syllables developed, but then the low-mid vowels /ɛ ɔ/ merged into the high-mid vowels /e o/. This system is still preserved, largely or completely, in all of the conservative Romance languages (e.g. Italian, Spanish, Portuguese, Catalan).
In final unstressed syllables, results were somewhat complex. One of the more difficult issues is the development of final short -u, which appears to have been raised to /u/ rather than lowered to /o/, as happened in all other syllables. However, it is possible that in reality, final /u/ comes from long *-ū < -um, where original final -m caused vowel lengthening as well as nasalization. Evidence of this comes from Rhaeto-Romance, in particular Sursilvan, which preserves reflexes of both final -us and -um, and where the latter, but not the former, triggers metaphony. This suggests the development -us > /ʊs/ > /os/, but -um > /ũː/ > /u/.
The original five-vowel system in final unstressed syllables was preserved as-is in some of the more conservative central Italian languages, but in most languages there was further coalescence:
The so-called intertonic vowels are word-internal unstressed vowels, i.e. not in the initial, final, or tonic (i.e. stressed) syllable, hence intertonic. Intertonic vowels were the most subject to loss or modification. Already in Vulgar Latin intertonic vowels between a single consonant and a following /r/ or /l/ tended to drop: vétulum "old" > veclum > Dalmatian vieklo, Sicilian vecchiu, Portuguese velho. But many languages ultimately dropped almost all intertonic vowels.
Generally, those languages south and east of the La Spezia–Rimini Line (Romanian and Central-Southern Italian) maintained intertonic vowels, while those to the north and west (Western Romance) dropped all except /a/. Standard Italian generally maintained intertonic vowels, but typically raised unstressed /e/ > /i/. Examples:
Portuguese is more conservative in maintaining some intertonic vowels other than /a/: e.g. *offerḗscere "to offer" > Portuguese oferecer vs. Spanish ofrecer, French offrir (< *offerīre). French, on the other hand, drops even intertonic /a/ after the stress: Stéphanum "Stephen" > Spanish Esteban but Old French Estievne > French Étienne. Many cases of /a/ before the stress also ultimately dropped in French: sacraméntum "sacrament" > Old French sairement > French serment "oath".
The Romance languages for the most part have kept the writing system of Latin, adapting it to their evolution. One exception was Romanian before the nineteenth century, where, after the Roman retreat, literacy was reintroduced through the Romanian Cyrillic alphabet, a Slavic influence. A Cyrillic alphabet was also used for Romanian (Moldovan) in the USSR. The non-Christian populations of Spain also used the scripts of their religions (Arabic and Hebrew) to write Romance languages such as Ladino and Mozarabic in aljamiado.
The Romance languages are written with the classical Latin alphabet of 23 letters – A, B, C, D, E, F, G, H, I, K, L, M, N, O, P, Q, R, S, T, V, X, Y, Z – subsequently modified and augmented in various ways. In particular, the single Latin letter V split into V (consonant) and U (vowel), and the letter I split into I and J. The Latin letter K and the new letter W, which came to be widely used in Germanic languages, are seldom used in most Romance languages – mostly for unassimilated foreign names and words. Indeed, in Italian prose kilometro is properly chilometro. Catalan eschews importation of "foreign" letters more than most languages. Thus Wikipedia is Viquipèdia in Catalan but Wikipedia in Spanish.
While most of the 23 basic Latin letters have maintained their phonetic value, for some of them it has diverged considerably; and the new letters added since the Middle Ages have been put to different uses in different scripts. Some letters, notably H and Q, have been variously combined in digraphs or trigraphs (see below) to represent phonetic phenomena that could not be recorded with the basic Latin alphabet, or to get around previously established spelling conventions. Most languages added auxiliary marks (diacritics) to some letters, for these and other purposes.
The spelling rules of most Romance languages are fairly simple, and consistent within any language. Since the spelling systems are based on phonemic structures rather than phonetics, however, the actual pronunciation of what is represented in standard orthography can be subject to considerable regional variation, as well as to allophonic differentiation by position in the word or utterance. Among the letters representing the most conspicuous phonological variations, between Romance languages or with respect to Latin, are the following:
Otherwise, letters that are not combined as digraphs generally represent the same phonemes as suggested by the International Phonetic Alphabet (IPA), whose design was, in fact, greatly influenced by Romance spelling systems.
Since most Romance languages have more sounds than can be accommodated in the Roman Latin alphabet they all resort to the use of digraphs and trigraphs – combinations of two or three letters with a single phonemic value. The concept (but not the actual combinations) is derived from Classical Latin, which used, for example, TH, PH, and CH when transliterating the Greek letters "θ", "ϕ" (later "φ"), and "χ". These were once aspirated sounds in Greek before changing to corresponding fricatives, and the H represented what sounded to the Romans like an /ʰ/ following /t/, /p/, and /k/ respectively. Some of the digraphs used in modern scripts are:
While the digraphs CH, PH, RH and TH were at one time used in many words of Greek origin, most languages have now replaced them with C/QU, F, R and T. Only French has kept these etymological spellings, which now represent /k/ or /ʃ/, /f/, /ʀ/ and /t/, respectively.
Gemination, in the languages where it occurs, is usually indicated by doubling the consonant, except when it does not contrast phonemically with the corresponding short consonant, in which case gemination is not indicated. In Jèrriais, long consonants are marked with an apostrophe: s's is a long /zz/, ss's is a long /ss/, and t't is a long /tt/. The phonemic contrast between geminate and single consonants is widespread in Italian, and normally indicated in the traditional orthography: fatto /fatto/ 'done' vs. fato /fato/ 'fate, destiny'; cadde /kadde/ 's/he, it fell' vs. cade /kade/ 's/he, it falls'. The double consonants in French orthography, however, are merely etymological. In Catalan, the gemination of l is marked by a punt volat ("flying point"): l·l.
Romance languages also introduced various marks (diacritics) that may be attached to some letters, for various purposes. In some cases, diacritics are used as an alternative to digraphs and trigraphs; namely to represent a larger number of sounds than would be possible with the basic alphabet, or to distinguish between sounds that were previously written the same. Diacritics are also used to mark word stress, to indicate exceptional pronunciation of letters in certain words, and to distinguish words with same pronunciation (homophones).
Depending on the language, some letter-diacritic combinations may be considered distinct letters, e.g. for the purposes of lexical sorting. This is the case, for example, of Romanian ș ([ʃ]) and Spanish ñ ([ɲ]).
The following are the most common use of diacritics in Romance languages.
Most languages are written with a mixture of two distinct but phonetically identical variants or "cases" of the alphabet: majuscule ("uppercase" or "capital letters"), derived from Roman stone-carved letter shapes, and minuscule ("lowercase"), derived from Carolingian writing and Medieval quill pen handwriting which were later adapted by printers in the fifteenth and sixteenth centuries.
In particular, all Romance languages capitalize (use uppercase for the first letter of) the following words: the first word of each complete sentence, most words in names of people, places, and organizations, and most words in titles of books. The Romance languages do not follow the German practice of capitalizing all nouns including common ones. Unlike English, the names of months, days of the weeks, and derivatives of proper nouns are usually not capitalized: thus, in Italian one capitalizes Francia ("France") and Francesco ("Francis"), but not francese ("French") or francescano ("Franciscan"). However, each language has some exceptions to this general rule.
The tables below provide a vocabulary comparison that illustrates a number of examples of sound shifts that have occurred between Latin and Romance languages. Words are given in their conventional spellings. In addition, for French the actual pronunciation is given, due to the dramatic differences between spelling and pronunciation. (French spelling approximately reflects the pronunciation of Old French, c. 1200 AD.)
