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 would be a gender best described by the sea). They are particularly useful for synesthetic people. Noungenders are very flexible and personal. There are a lot of similarities, and often a lot of overlap between noungenders and aesthetigenders. However, noungenders describe genders as being or being like a thing, while aesthetigenders describe genders as having a similar aesthetic or being aesthetically related to something.
