We add prefixes before words and suffixes after words to change their meanings. Prefixes can change the meaning by denoting before, against, not, again, between, self, above, under, far, or liking. Suffixes can change the meaning to denote being able to be done, being full of, being without, a state of being, or acting as an adverb, and they can also form the past tense of verbs. Many prefixes and suffixes come from Greek origins.
