Trigender

Trigender people experience three genders, at the same time, or moving between the three at different times. These three genders can be any gender, either binary or nonbinary. A trigender person may change from expressing one gender to another, depending on that person's mood or situation. Someone who identifies as trigender may feel that their gender is a combination of several genders happening at the same time. Trigender falls under the general categories of multigender (having many genders) and sometimes genderfluid (having genders that change from time to time). It can also be considered a type of genderqueer or nonbinary identity, which goes beyond the Western binary gender system, much as can be seen in cultures that recognize individuals' right to define their own sense of self

In most Western societies, straying outside of the gender dichotomy is seen as socially unacceptable to the patriarchy. The term third gender has been applied to to many kinds of people, even to white Westerners themselves, who do not conform into rigid categories of heterosexual roles and gender-conforming men and women. The phrase "third gender" has been used for a wide variety of meanings: intersex people whose bodies do not fit outdated Western medical concepts of binary sex, hundreds of indigenous societal roles as described (and often misrepresented) by Western anthropologists (including indigenous identities such as south Asian hijras, Hawaiian and Tahitian māhū, and Native American identities now called Two-Spirits), transgender people who are nonbinary, homosexual people even in Western societies, and women who were considered to be gender-nonconforming because they fought for women's rights. A significant number of nonbinary people have adopted "third gender" to describe themselves. In the 2019 Worldwide Gender Census, 2.17% (244) of the 11,242 respondants called themselves third gender.

History
The word "trigender" was in use at least before 1999. Trigender was mentioned as one of many valid nonbinary identities in the 2013 text Sexuality and Gender for Mental Health Professionals: A Practical Guide. In the 2019 Worldwide Gender Census, 14 respondents called themselves trigender.
