Antonyms are words that have opposite meanings. For example, an antonym of day is night, and an antonym of on is off. The term antonym comes from antonymy, which is the technical grammar term for words that have contradictory meanings—but you can think of antonyms as opposites.

Antonyms are words with opposite meanings. For example, 'good' is an antonym of 'bad.' It is possible for a word to have more than one antonym as antonyms can be graded. They can be used to make writing more interesting, to form deliberate double negatives, and to improve vocabulary.

An antonym is a word that has the opposite or inverted meaning of another word. For instance, start and stop, as well as good and evil, are antonyms. Antonyms can be any word, including verbs, nouns, adjectives, adverbs, and prepositions.

There are three types of antonyms. Graded antonyms are pairs of words with opposite meanings which are on a continuous spectrum. Some examples of graded antonyms are hard and soft, best and worst, wet and dry. Complementary antonyms are contradictory, something is either one or the other without any degree of differentness.
