Opposite (semantics)

In lexical semantics, opposites are words lying in an inherently incompatible binary relationship, like the opposite pairs big : small, long : short, 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. It is referred to as a 'binary' relationship because there are two members in a set of opposites. The relationship between opposites is known as opposition.
