Prefix: Mono- or Uni-
Main Umbrella: Metagender
GxG Format: 1?

Gender(s): Any

Monogender or Unigender is the experience of identifying as only one gender, the prefix 'mono' meaning “One, Only, Single”, and 'uni' meaning “One” and is used as a compound word. [1]

The described gender can be any gender as long as it is only a single gender. Individuals that experience gender fluidity can also be monogender, as long as they only experience one gender at a time. Combinations of genders can sometimes also be considered monogender, such as androgyne (a gender between man and woman), in comparison to bigender that involves two genders (where one might be both a man and a woman).


It is unclear when monogender was first coined, but may have been incidentally coined by various individuals due to the common understanding of the prefix 'mono'.
