An affix is a morpheme (a meaningful linguistic unit) that is attached to a root word to create a new word or inflect its meaning. It can be a prefix (attached at the beginning of a word), a suffix (attached at the end of a word), or an infix (inserted within a word).
An affix is a bound morpheme that is attached to a base word to create a new word, while a suffix is a specific type of affix that is attached to the end of a base word. Suffixes typically change the grammatical function or meaning of the base word.
