Aingender (shortened to Ain) is a term for all genders which are aporine in nature (AIN). It can be used as an umbrella term for any genders that are not related to masculinity, femininity, or anything in between, but are still strongly gendered. It can also be used as a gender on its own, referring to any gender that may not be fully defined by aporinity but but is still related to aporinity, or a gender in which aporinity is its defining feature but the gender is not purely aporagender or atrinary. It's often used by people who cannot narrow down their gender any more than being aporine, but still definitely not fully atrinary.
History
Aingender was coined by 'ap' at Beyond-Mogai-Pride-Flags on June 26, 2018.[1] It was originally defined as "umbrella term for all genders aporine in nature. May simply be used as “ain”, ie. “my gender is ain”."[2]
It was later redefined by Wiki user Chaoticcylinder, upon the making of the page.[3] The reason for this redefinition is unknown.
