Stargender

Stargender is a term that has at least three possible definitions.

1) A xenogender in which one's gender is or is like a star. Subgenders for this definition can also exist, for example, one's gender might be specifically a blue star, therefore being an O-stargender or B-stargender. Other terms might include A-stargender, F-stargender or G-stargender for other types of stars. In addition, a stargender person might identify as a binary or multiple star system. 2) A other-worldly, non-human gender which is beyond comprehension in earthly terms, as if it originated from beyond the Earth. According to the coiner of the term it was similar to aliagender, and is related to it, however stargender specifically related to outer space and/or other worldliness.

3) A gender that cannot be defined no matter how many other terms are coined.

History
