A term used to describe some people whose gender expression is different from conventional expectations of masculinity and femininity. Please note that not all gender non-conforming people identify as transgender; nor are all transgender people gender non-conforming. Many people have gender expressions that are not entirely conventional – that fact alone does not make them transgender. Many transgender men and women have gender expressions that are conventionally masculine or feminine. Simply being transgender does not make someone gender non-conforming. The term is not a synonym for transgender or transsexual and should only be used if someone self-identifies as gender non-conforming. It is best to ask gender non-conforming people which pronouns they prefer.
