niagender could be a thing, the ningender version of (l/m/f)iagender. and maybe xiagender as the xingender
I coined fia-/mia-/lia- to make it easier to say things like “women, nonbinary women, partial women, anyone who is woman-aligned/adjacent, or anyone with a FINgender” (the alternative, of course, being “fiaspec & FINgender people”). It seems like “Niagender Spectrum” would essentially be synonymous to (what I’ve been calling) the neutral (gender) spectrum. Same for xiaspec/xeno spec, aiaspec/apora spec, & agiaspec/agen spec.
That said, I do appreciate the uniformity, & their usage could help to differentiate terms by one spectrum being “genders which are [neutral/xenine/aporine/null]” and the other being (more broadly) “genders which are [x], partially [x], or [x]-aligned/adjacent.”
Here are the definitions I’d propose:
Niagender Spectrum / Niaspec: an umbrella term similar to NINgender for anyone on the “neutrally gendered” spectrum; anyone whose gender is neutral, partly neutral, or in some way similar to/resemblant of gender neutrality. Can also be used as a gender identity all on its own.
Xiagender Spectrum / Xiaspec: an umbrella term similar to XINgender for anyone on the “xenogendered” spectrum; it includes all xenogenders, partial xenogenders, and genders which are in some way similar to/resemblant of xeninity. Can also be used as a gender identity all on its own.
Aiagender Spectrum / Aiaspec: an umbrella term similar to AINgender for anyone on the “aporagendered” spectrum; it includes all aporagenders, partial aporagenders, and genders which are in some way similar to/resemblant of aporinity. Can also be used as a gender identity all on its own.
Agiagender Spectrum / Agiaspec: an umbrella term similar to AGINgender for anyone on the “genderless” spectrum; it includes anyone who does not have a gender, only partly or sometimes has a gender, or whose gender is in some way similar to/resemblant of genderlessness. Can also be used as a gender identity all on its own.
