An affix is a morpheme that is attached to a base morpheme to form a word. An affix can be a prefix (attached before another morpheme), a suffix (attached after another morpheme), an infix (inserted within another morpheme), a circumfix (attached before and after another morpheme), or a suprafix (attached suprasegmentally to another morpheme). Affixes are bound morphemes by definition. Prefixes and suffixes may be separable affixes.
Affixes are central to the process of agglutination.
