Non-binary gender identities that are not fully defined through the traditional concepts of gender are referred to as xenogender. Instead of being defined through the use of gender concepts, they can be described through how they connect to other concepts or things.
Although xenogender individuals have a strong sense of their gender's feelings, they often feel that there are no words for their experiences. To fill this gap, they often describe their gender using metaphors.
When described, xenogenders often fall into one of three categories:
1-noungenders and noununs are terms that refer to the gender of an animal or a symbol.
2-Synaesthetic Perceptions are the terms used for describing the various characteristics of a gender, such as shape, size, and sound.
3-Neurotypes are often associated with a person's gender identity.
