Demotic Greek or Dimotiki (Greek: Δημοτική Γλώσσα, Dimotikí Glóssa, [ðimotiˈki], lit. "language of the people") is a term used in contrast with Katharevousa to describe the colloquial vernacular form of Modern Greek which had evolved naturally from Koine Greek and was spoken by the vast majority of Greeks in Greece during the time of diglossia in the modern Greek state from the time of its founding in 1821 until the resolution of the Greek language question in 1976. In this context Dimotiki describes the specific non-standardized vernacular forms of Greek used by the vast majority of Greeks throughout the 19th and 20th centuries. During this long period of diglossia, Katharevousa and Dimotiki complemented and influenced each other, as is typical of diglossic situations. Dimotiki became standardized over time and it was this standardized form of Dimotiki which in 1976 was made the official language of Greece. This standardized form of Dimotiki is today known formally as Standard Modern Greek. The term demotic Greek (with a lowercased d) is also a term used generally to refer to any variety of the Greek language which has evolved naturally from Ancient Greek and is popularly spoken.
Demotic Greek differs from varieties of Ancient Greek and learned forms inherited from the same in several important ways. Syntactically, it favors parataxis over subordination. It also heavily employs redundancy, such as μικρό κοριτσάκι (small little-girl) and ξανακοιμήθηκε πάλι (he-went-back-to-sleep again). Somewhat in connection with this, Demotic employs the diminutive with great frequency,: XI to the point that many Demotic forms are in effect neuter diminutives of ancient words, especially irregular ones, e.g. νησί from νήσιον (island) from ancient νῆσος (island).
Greek noun declensions underwent considerable alteration, with irregular and less productive forms being gradually replaced by more regular forms based on the old one: άντρας (man) for ancient ἀνήρ. Another feature was the merging of classical accusative and nominative forms, distinguishing them only by their definite articles, which continued to be declined as in Ancient Greek. This was especially common with nouns of the third declension, such as πατρίς (hometown, fatherland) which became nominative η πατρίδα, accusative την πατρίδα in Demotic.: X Another feature of the evolution of Demotic was the near-extinction of the genitive plural, which was revived in Katharevousa and is now productive again in Demotic.
A derivative feature of this regularization of noun forms in Demotic is that the words of most native vocabulary end in a vowel, or in a very restricted set of consonants: s and n (ς, ν). Exceptions are foreign loans like μπαρ (bar), and learned forms ύδωρ (from Ancient Greek ὕδωρ, water), and exclamations like αχ! (ach!, oh!) Many dialects go so far as to append the vowel -e (ε) to third-person verb forms: γράφουνε instead of γράφουν (they write). Word-final consonant clusters are also rare, again mainly occurring in learned discourse and via foreign loans: άνθραξ (coal – scientific) and μποξ (boxing – sport).: 8–9
Indirect object is usually expressed by σε with the accusative where Ancient Greek had εἰς for accusative of motion toward; bare σε is used without the article to express indefinite duration of time, or contracted with the definite article for definiteness especially with regard to place where or motion toward; or with the genitive, especially with regard to means or instrument.: X Using one noun with an unmarked accusative article-noun phrase followed by σε contracted with the definite article of a second noun distinguishes between definite direct and indirect objects, whether real or figurative, e.g. «βάζω το χέρι μου στο ευαγγέλιο» or «...στη φωτιά» (lit. I put my hand upon the Gospel or ...in the fire, i.e. I swear it's true, I'm sure of it). By contrast, Katharevousa continued to employ the ancestral form, εἰς, in place of σε.
The verb system inherited from Ancient Greek gradually evolved, with the old future, perfect and pluperfect tenses gradually disappearing; they were replaced with conjugated forms of the verb έχω (I have) to denote these tenses instead. The future tenses and the subjunctive and optative moods, and eventually the infinitive, were replaced by the modal/tense auxiliaries θα and να used with new simplified and fused future/subjunctive forms.: X In contrast to this, Katharevousa employed older perfective forms and infinitives that had been for the most part lost in the spoken language, but in other cases it employed the same aorist or perfective forms as the spoken language, but preferred an archaizing form of the present indicative, e.g. κρύπτω for Demotic κρύβω (I hide), which both have the same aorist form έκρυψα.: XI
Demotic Greek also borrowed a significant number of words from other languages such as Italian and Turkish, something which katharevousa avoided.
Dimotiki is sometimes used interchangeably with "Standard Modern Greek" (Νέα Ελληνικά), but these two terms are not necessarily synonymous. While in Greek the term Δημοτική (Dimotikí) can describe any naturally evolved colloquial language of the Greeks, today's Standard Modern Greek language can be thought of specifically as a fusion of Katharevousa and the specific Dimotiki spoken by in Greece in the 20th century. It is not wrong to call the Greek language of today "a Greek", but such terminology may lead to confusion with the semi-standardized Dimotiki which was in use during the period of diglossia in Greece and is not identical to today's Standard Modern Greek.
Referring to Standard Modern Greek as Dimotiki or Demotic Greek (with a capital "D") also ignores the fact that today's Greek contains—especially in its written form and formal registers—numerous words, grammatical forms, and phonetical features that did not exist in the Dimotiki and which only entered the language through Dimotiki's merger with Katharevousa as part of the resolution of the Greek language question.
The following examples are intended to demonstrate Katharevousa's features in Modern Greek. They were not present in traditional Demotic and only entered the modern language through Katharevousa (sometimes as neologisms), where they are used mostly in writing (for instance, in newspapers), but also orally, especially words and fixed expressions are both understood and actively used also by non-educated speakers. In some cases, the Demotic form is used for literal or practical meanings, while the Katharevousa is used for figurative or specialized meanings: e.g. φτερό for the wing or feather of a bird, but πτέρυξ for the wing of a building or airplane or arm of an organisation.: 180 : 203
Modern Greek features many letter combinations that were avoided in classical Demotic:
Native Greek speakers often make mistakes in these "educated" aspects of their language; one can often see mistakes like προήχθη instead of προήχθην (I've been promoted), λόγου του ότι/λόγο το ότι instead of λόγω του ότι (due to the fact that), τον ενδιαφέρον άνθρωπο instead of τον ενδιαφέροντα άνθρωπο (the interesting person), οι ενδιαφέροντες γυναίκες instead of οι ενδιαφέρουσες γυναίκες (the interesting women), ο ψήφος instead of η ψήφος (the vote). However, the educated ones do not make mistakes often.
One of the most radical proponents of a language that was to be cleansed of all "educated" elements was Giannis Psycharis, who lived in France and gained fame through his work My Voyage (Το ταξίδι μου, 1888). Not only did Psycharis propagate the exclusive use of the naturally grown colloquial language, but he actually opted for simplifying the morphology of Katharevousa forms prescription.
For instance, Psycharis proposed changing the form of the neuter noun "light" το φως (gen. του φωτός) into το φώτο (gen. του φώτου). Such radical forms had occasional precedent in Renaissance attempts to write in Demotic, and reflected Psycharis' linguistic training as a Neogrammarian, mistrusting the possibility of exceptions in linguistic evolution. Moreover, Psycharis also advocated spelling reform, which would have meant abolishing most of the six different ways to write the vowel /i/ and all instances of double consonants. Therefore, he wrote his own name as Γιάνης, instead of Γιάννης.
As written and spoken Dimotiki became standardized over the next few decades, many compromises were made with Katharevousa (as is reflected in contemporary standard Greek) despite the loud objections of Psycharis and the radical "psycharist" (ψυχαρικοί) camp within the proponents of Dimotiki's use. Eventually these ideas of radical demoticism were largely marginalized and when a standardized Dimotiki was made the official language of the Greek state in 1976, the legislation stated that Dimotiki would be used "without dialectal and extremist forms"—an explicit rejection of Psycharis' ideals.
