Word Study: Patterns of Word Changes

Suffixes and prefixes can be added to base words to change their meanings. Often, suffixes change a word's part of speech. The base word space, a noun—from the Latin spatium—becomes spacious, an adjective, when the suffix -ious is added.

1. The word voice, when it is used as a verb, means "to speak out loud." Explain how this word is changed by the addition of the prefix un- and the suffix -ed.
2. Find two other examples in the story of words that contain either a prefix or a suffix. Explain how the meaning of the base word is changed by the addition of the prefix or suffix.
