affixe

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."
