The term "binate" refers to something that is present or occurs in pairs. Its antonyms, on the other hand, are words that denote a singular or plural state where two or more things, objects or entities are not present together. Some of the antonyms for "binate" include singular, unique, solitary, individual, alone, single or only. These terms indicate a state where there is no pairing or duplication but rather a singular entity. For example, a tree is an individual and a single entity and is therefore an antonym of binate, which refers to a pair of something.
