1. antonym
Wikipedia definition
2. Opposite (semantics)In lexical semantics, opposites are words that lie in an inherently incompatible binary relationship as in the opposite pairs male : female, long : short, up : down, and precede : follow. The notion of incompatibility here refers to the fact that one word in an opposite pair entails that it is not the other pair member. For example, something that is long entails that it is not short.
