Before its use in the LGBQT community, bigender was an early 20th-century biological term for plants that possess both male and female reproductive parts. The term evolved to refer to something suitable for both male and female genders, e.g., bigender college dorms, where men and women will live on the same floor. Bigender was applied to gender identity as early as the 1970s. That said, the concept of bigender long predates the term, as exemplified by the Native American concept of Two Spirits– a person embodying both male and female identities. Individuals who identify as bigender tend not to be considered gender-fluid, which is a nonbinary identity where a person is a non-fixed range of gender identities. Some individuals may experience three gender identities, or trigender. Bigender does not always mean a mix of male and female, it can be male and gender fluid or agender and genderqueer etc.
