  2. (linguistics, philosophy, semantics) A semantic relationship between two words wherein negative use of one entails the affirmative of the other with no gradability; the relation of binary antonyms.

      For complementarity, there are entailments both from affirmative sentences to the corresponding negative sentences (which is what ordinary antonymy allows) and from negative sentences to the corresponding affirmative sentences.
