For example, adding the prefix “un” to “happy” creates a new word, “unhappy.” When students master the use of prefixes, their vocabulary increases tremendously.

A prefix is what is called an “affix”— an additional element placed at the beginning or end of a root, stem or word to modify its meaning.
