Something that acts contrary or in opposition; in logic and mathematics, relating to statements or propositions that are contrary or mutually exclusive.
From 'contrary' (from Latin 'contrarius,' opposed) plus the suffix '-ant' (indicating an agent or quality). A specialized philosophical and mathematical term rarely used in everyday language.
In formal logic, 'contrary' statements are stronger than merely 'contradictory' ones—two contraries can both be false, but not both true, which opens fascinating possibilities for paradoxes.
