What is meaning of antonymous?

Antonym is a word that has opposite meaning to another word. For example, hot and cold, good and bad, love and hate are pairs of antonyms. Antonyms can be classified into several categories such as gradable antonyms, complementary antonyms, reverse antonyms, concrete antonyms and relational antonyms. Gradable antonyms represent two opposite ends of a continuum, for instance, tall and short. Complementary antonyms cannot coexist, for instance, alive and dead. Reverse antonyms are verbs that have opposite meanings, such as buy and sell. Concrete antonyms relate to physical properties, like light and heavy. Relational antonyms reveal a contrast in the way things relate to one another, such as employer and employee. Antonyms are used in literature and language to express contrast, add emphasis, and create humor.
