An Affix is a morpheme that is attached to a base morpheme to form a word form. An affix can be a prefix (something attached at the front), a suffix (attached at the back), an infix (in between) or a circumfix (two parts, one in front, the other at the back). Affixes are bound morphemes by definition.

Affixes are essential in agglutination.

Example:

to establish (verb) + suffix -ment -> establishment (noun) (see derivation)
