Noungender

Noungenders are a type of xenogender that can be best described as being, or being like, a thing, concept, animal, imaginary being, part of nature, or a symbol. For example, seagender is a noungender best described by the sea. They are particularly useful for synesthetes and otherkin, though noungenders usually do not have exclusivity to those groups. Noungenders are very flexible and personal. They have many similarities and overlap with aesthetigenders. However, noungenders describe genders as directly being or being like a thing, while aesthetigenders describe genders as having a similar aesthetic or being aesthetically related to something.

History
