A prefix is a beginning root that modifies the meaning of a word. Prefixes in English usually come from both Latin and Greek, so different prefixes can have the same meaning. The following collection of worksheets will help your students learn what different prefixes mean in order to use them correctly. Activities include assigning prefixes from a given list to specific words, giving them meaning, changing words into their opposites, and more. Answer keys are provided.
Note: Similar-sounding prefixes don’t always mean the same thing. "Ante-" is from Latin which means "before," while "anti-" is from Greek that means "against."
