word study derivations
derivations are words that are related to, but have different meanings than another word. prefixes are word - parts added to the beginning of a base word to create a derivation of the base word. suffixes are word - parts added to the end of a base word to create a derivation. adding a prefix and/or a suffix can also change a words part of speech. for example, defend is a verb meaning \protect, resist, or fight for.\ however, if you add the prefix un - to the past tense of defend, the word becomes undefended, or
ot protected.\ note the other ways a prefix and/or a suffix can change defend into an adjective: defensive, defensible, indefensible. here are some examples of prefixes and suffixes:

prefixes	suffixes
