Cisgender

Cisgender describes someone whose gender identity matches their assigned sex at birth: registered female at birth, has always known herself to be a woman — a cisgender woman. The prefix comes from Latin cis- (“on the same side”), the counterpart of trans- (“across”), a pairing long used neutrally in chemistry and other fields. The Chinese rendering 顺性别 (shun xingbie) uses 顺, “going along with.”

The word’s real value is that it names the default. Before it existed, the language offered only “transgender people” and “normal people” — and the unnamed side automatically became the standard, while the named side became the exception. With “cisgender,” the two experiences become parallel descriptions of equal standing, like “right-handed” and “left-handed.” It is a descriptor, not an accusation, and not a slur.

Register note: standard in formal and academic contexts; in community speech it’s usually shortened to “cis” (Chinese: 顺).

Common misuse: first, conflating it with orientation — cisgender does not mean heterosexual; cis people can be gay, bi, or asexual. Second, taking “cisgender” as an insult — like “transgender,” it simply states whether identity and assigned sex align.
