Worksheet Overview

An antonym is a word that means the opposite of another word.

Some antonyms are completely different words, but others can be formed by adding a prefix to the existing word.


helpful    unhelpful

like    dislike

patient    impatient


impatient child


Dictionaries and thesauruses can be very helpful if you are not sure which prefix to use to form an antonym.
