Angynby

Angynby, also known as androgynby or endrogyne, is a term for someone who is a non-binary androgyne person. Since androgyne is technically included under the non-binary umbrella, this does not just refer to someone who is androgyne, but to someone who is both androgyne and another non-binary identity, like neutrois, juxera, etc. It can refer to several different things-

A multigender person who is both androgyne and another non-binary gender (they may be other genders as well)
A monogender person who feels their gender is a singular "fusion" of androgyne and another non-binary gender
A person whose gender is some percent androgyne and some percent another non-binary gender, making both only partial components of their gender and therefore demigender components
A genderfluid person who is fluid between androgyne and another non-binary gender (they may be fluid between other genders as well)
Someone who is inbetween androgyne and non-binary
Someone who is androgynous-aligned non-binary, null/neutral-aligned androgyne, or both

Demangynby

Demangynby (or demiandrogynby or demiendrogyne) is a gender identity which can refer to a few different things-

A multigender person who is both demiandrogyne and deminonbinary (they may be other genders as well)
A monogender person who feels their gender is a singular "fusion" of demiandrogyne and deminonbinary
A person whose gender is some percent demiandrogyne and some percent deminonbinary, making both only partial components of their gender and therefore demigender components
A genderfluid person who is fluid between demiandrogyne and deminonbinary (they may be fluid between other genders as well)
