Complementary is a sense relation holding between any pair of predicates <P, Q> that fulfills the following conditions: If a referent x has property P, it cannot have property Q, and if x does not have property P, it has property Q:
- P → not Q
not P → Q
Complementarity is a special case of incompatibility.
