Leptrois

Leptrois, also known as leptive or leptral gender system is a gender classification that brings mathematical and linguistic understanding of genders, such as between negative and positive, negatrois and positrois. It encompasses nullity, ambivalence, infinity and many other concepts. It's also used to communicate gender arity, as in leptary, such as atrinary, abinary, (a-genders) anonbinary, non-binary (as a nongender), zerogender and eugender.

Neutrois, or gender neutrality, is theorized as the middle in the whole gender spectrum, represented by centrois and zero (0), nullity by empty space (null sign: ∅).
