10 SLIDE 1. Contradictories represent the type of semantic relations that exist between pairs like dead – alive, single – married. Contradictory antonyms are mutually opposed, they deny one another. Contradictories form a privative binary opposition, they are members of two-term sets. To use one of the words is to contradict the other and to use ‘not’ before one of them is to make it semantically equivalent to the other: not dead – alive, not single – married. 2. Contraries are antonyms that can be arranged into a series according to the increasing difference in one of their qualities. The most distant elements of this series will be classified as contrary notions. Contraries are gradable antonyms, they are polar members of a gradual opposition which may have intermediate elements. This may be observed in cold – hot and cool – warm which are intermediate members. Thus, we may regard as antonyms not only cold and hot but also cool and warm. Contrary antonyms may also be considered in terms of degrees of the quality involved. Thus, water may be cold and very cold, and water in one glass may be colder than in another one.
3. Incompatibles are antonyms which are characterized by the relations of exclusion. Semantic relations of incompatibility exist among antonyms with a common component of meaning and may be described as the reverse of hyponymy. For example, to say morning is to say not afternoon, not evening, not night. The use of one member of this set implies the exclusion of the other members of the set. Incompatibles differ from contradictories as incompatibles are members of the multiple-term sets while contradictories are members of two-term sets. A relation of incompatibility may be also observed between colour terms since the choice of red, for instance, entails the exclusion of black, blue, yellow, etc.
