Gender Septenary
In my opinion, if gender is not a binary, it is a septenary (arity of seven). That is not to say that there are seven genders in total, but rather most gender identities that exist can be sorted into seven distinct categories.
Nonmonogenders are also included in this, but I'm treating them as amative genders here. Nonmonogenders can be used to modify any gender in the gender septenary.
Most genders can be sorted into one of these categories: Female-aligned, Male-aligned, Neutral-aligned, Genderless-aligned, Xenic-aligned, Outheric/Aporine-aligned, Unlabled/Unknown.
Androgynous genders are both female and male, either as centrigenders, gendermixes, or multigenders.
Any genders that do not fit into any of these categories can be called aseptenary and can challenge this structure further. This isn't meant to be a definitive or absolute categorization of gender; it is bound to be pushed, rejected, and challenged.
