Ternary or trinary genders are three primary pre-existing gender identities accessible within ones own culture. This gender arity usually includes binary genders and a tertiary gender. This tertiary identity can be a third gender or other abinary identity, such as neutrois/neither (or none), or liaspec centrigender, such as androgyne/both, generally monogender, not necessarily allogender.
Gender trinarism is often considered a form of exorsexist discrimination towards non-trinary and atrinary individuals, reinforcing an extension of gender binarism. It could be either in ways of language or identity.
It may also affect non-binary/binaryn't and gender/pronoun non-conforming individuals, such as enforcing trinary expectations of men using he/him pronouns and having masculine presentation, women using she/her pronouns and being feminine, or non-binary individuals using they/them and looking androgynous or neutral.
Gender trinary may also be known as gender trichotomy.
History It was then conditionally used interchangeably with gender quaternary, as both and neither can be two tertiary identities.
In June 2018, Tumblr user exorsexistbullshit defines gender trinarism as the idea that all non-binary people are just a separate gender from women and men. The term is later used in some academic articles.
