Urse or Ursule is the diamoric version of bear and ursula, describing beary non-binary.[1]
As ursa and urso are gendered words for bears, ursine or bearish in Romance languages, the suffix -e is added to neutralize as a neologism, just as Latine and niñe. Other endings may apply, such as ursx, ursulx, ursy, etc.
