Suffix

In linguistics, a suffix is an affix which is placed after the stem of a word. Common examples are case endings, which indicate the grammatical case of nouns, adjectives, and verb endings, which form the conjugation of verbs. Suffixes can carry grammatical information (inflectional suffixes) or lexical information (derivational/lexical suffixes). An inflectional suffix is sometimes called a desinence[1][better source needed] or a grammatical suffix.[2] Such inflection changes the grammatical properties of a word within its syntactic category. For derivational suffixes, they can be divided into two categories: class-changing derivation and class-maintaining derivation.

Particularly in the study of Semitic languages, suffixes are called afformatives,[3] as they can alter the form of the words. In Indo-European studies, a distinction is made between suffixes and endings (see Proto-Indo-European root). Suffixes can carry grammatical information or lexical information.

A word-final segment that is somewhere between a free morpheme and a bound morpheme is known as a suffixoid[4] or a semi-suffix[5] (e.g., English -like or German -freundlich "friendly").

Inflection changes the grammatical properties of a word within its syntactic category. In the example:

the suffix -ed inflects the root-word fade to indicate past participle.

Inflectional suffixes do not change the word class of the word after the inflection.[7] Inflectional suffixes in Modern English include:

Derivational suffixes can be divided into two categories: class-changing derivation and class-maintaining derivation.[8] In English, they include
