Transitioning

A series of processes that some transgender people may undergo in order to live more fully as their true gender. This typically includes social transition, such as changing name and pronouns, medical transition, which may include hormone therapy or gender affirming surgeries, and legal transition, which may include changing legal name and sex on government identity documents. Transgender people may choose to undergo some, all or none of these processes.

Non-Binary

Non-binary and genderqueer are umbrella terms for gender identities that are not solely male or female. Non-binary identities fall under the transgender umbrella, since non-binary people typically identify with a gender that is different from their assigned sex, though some non-binary people do not consider themselves transgender.
