In linguistics, an affix is a morpheme that is attached to a word stem to form a new word or word form. The main two categories are derivational and inflectional affixes. Derivational affixes, such as un-, -ation, anti-, pre- etc., introduce a semantic change to the word they are attached to. Inflectional affixes introduce a syntactic change, such as singular into plural (e.g. -(e)s), or present simple tense into present continuous or past tense by adding -ing, -ed to an English word. All of them are bound morphemes by definition; prefixes and suffixes may be separable affixes.
An affix is a piece of language attached to a word to create a new word or change its form—common examples include prefixes like "un-" and suffixes like "-ing" or "-ed." Affixes matter because they allow us to expand vocabulary and modify words to express different meanings and grammatical functions, like turning "happy" into "unhappy" or "walk" into "walking."

==Affixes, infixes and their variations== Changing a word by adding a morpheme at its beginning is called prefixation, in the middle is called infixation, and at the end is called suffixation.
