Some non-binary people may use gender-neutral words to describe themselves. Many non-binary people prefer to be called the pronoun "they" instead of "she" or "he". Other pronouns like "xe" or "ey" may be used, these are known to be neopronouns. This also includes noun-self pronouns, such as "bunself," in which the pronoun is tied directly to an alternative expression of gender. This is most common with xenogenders, in which the gender is described by the closest approximation of gender the individual feels and/or is most accurate. While gender neutral pronouns have existed in many languages and cultures, specific neopronouns in English can be found as early as the 1920's in David Lindsay's "A Voyage to Arcturus" in which the neopronoun "ae" is used. However, as individuals, nonbinary may choose whatever pronouns suit them best.
