module 3 PREFIXES AND SUFFIXES Prefixes and suffixes are sets of letters that are added to the beginning or end of another word. They are not words in their own right and cannot stand on their own in a sentence: if they are printed on their own they have a hyphen before or after them. Key to the abbreviations: adj. = adjective, adv. = adverb, n. = noun, v. = verb. PREFIXES are added to the beginning of an existing word in order to create a new word with a different meaning.
