The following worksheets will teach your students how to construct and use antonyms.

Instructors can use these pages to give their students practice with antonyms. Activities include filling in blanks or matching words using antonyms from a word bank, using prefixes to build antonyms out of root words, rewriting sentences to change their meaning into the opposite, and more. Context is very important when working with antonyms, because the opposite of “cool” can be “warm” if you’re talking about the weather, or “square” if you’re talking about a person.

Fun Fact: Words whose different definitions are antonyms, such as cleave (to hold together or split apart) and sanction (to boycott or approve), are called “contronyms.”
