usage note for themself
However, when themself is being used as part of a set of pronouns (including they, their, and them ) that refer back to a nonbinary or gender-nonconforming individual, it is a grammatical option to express reflexive meaning. Neither plural themselves nor gendered himself or herself completely suffice in this context. The grammaticality of nonbinary singular themself in this paradigm follows logically from the acceptability of singular they in this function: Andi is learning to put themself first, and prioritize their own happiness and mental health. See also they.
