Neuter

Neuter is an unlabeled experience similar to neutrois or gender-neutral. It's different in the sense that one refuses to define oneself under a gender term.

Characteristics
Yet neuter is described as a grammatical gender parallel with/to masculine and feminine, it's not commonly used as a gender identity or experience, therefore neuter is equiparable to both none and neither.

It can also be a translation of the Portuguese neolingual term neutre, which is an othergender balancing positive, negative, and null, hence it's adherently a gender quality, that is essentially not presentational.

Neutering
Neutering can also mean to castrate, remove the genitals from a being, most commonly associated with male dogs. Its sapi equivalent can be nullification or emasculation, including penectomy/phallectomy in POP, orchiectomy/testectomy/scrotectomy, ovariectomy/oophorectomy in Pwibs, vaginectomy/vulvectomy in POV, and clitorectomy.
