This document defines antonyms and provides examples. It begins by stating that antonyms are words with opposite meanings. There are three types of antonyms: gradable antonyms which have levels like beautiful and ugly, complementary antonyms which are absolute opposites like alive and dead, and converse antonyms which are pairs like above and below. Examples of hot and cold, fast and slow are given. Two exercises with words and their antonyms are provided for practice.
