Andersylph
Andersylph is an andergender identity in which one's gender is both xenogender/xenine and outherine in some way(s).
There are many reasons why one may use andersylph as a label for themselves. Examples include feeling xenogender/xenic but also outherine (or vice versa) or both at once, two separate parts of the gender are respectively xenic and outherine, the gender is fluid/flux/fluix between xenic and outherine genders, and the xenity being stagnant while outherine is fluid (or vice versa). These are only examples; anyone who feels that the label fits them may use it.
The androgynous counterpart to andersylph is anderdawn, the masculine counterpart is anderfaun, the non-binary counterpart is anderfae, the feminine counterpart is anderdoe, and the genderless/null counterpart is andersans.
