Columns: Identify the matching terms in two columns.

Prefixes re-, pre-, and un-

A prefix is a group of letters added to the beginning of a word to change its meaning.
Look at the prefixes re-, pre-, and un-.

re- means again
For example, reheat (heat again) and reapply (apply again)

pre- means before
For example, prewrite (write before) and prehistoric (before history)

un- means not
For example, unable (not able) and unusual (not usual)

Now choose the correct word for each sentence by thinking about what the prefix means
and how the word is used in the sentence. For extra help, the meaning of the missing
word is given after the sentence.
