(形容詞) 心理認同自己的生理性別的。亦寫成 cis-gender, cisgendered。這個字是由拉丁文字首 cis- (意為「與…同一邊」- "the same side as") 與 gender (性別) 組合而成,為比較常見的 transgender (註) 的反義詞。

註:transgernder 或 transgendered (形容詞) 意為「(未進行變性手術的) 變性的」,指生理是男性,但心理認同卻偏向女性或生理是女性,但心理認同卻偏向男性的人。當然了,絕大多數人都屬於 cisgender,僅極少數人為 transgender。

But when you have a term for one group of people, you need a word for the rest, and the one they've come up with is "cisgender". So the huge majority of us are now, "members of the cisgender community".

"We don't call being cisgender — which is when our bodies match up with our internal sense of gender — a personal choice. Both are about being who you are," she said.
