Prefixes and Suffixes What are they? Examples of common prefixes and suffixes The presentation made by Serbina and Zholtikova
prefix A prefix is a group of letters added to the beginning of a word. A prefix changes the meaning of the word, but NOT the part of speech.
UN UN is a prefix that means “not.” It changes the meaning of a word to the opposite. *However, the part of speech has not changed. happy is an adjective, and unhappy remains an adjective.
MIS MIS is a prefix that means “bad or wrong.” It changes the meaning of a word to a negative one. *However, the part of speech has not changed. behave is a verb, and misbehave remains a verb.
suffix A suffix is a group of letters added to the end of a word. A suffix changes the part of speech of the word, but NOT the meaning.
