What does cisgender mean?
Cisgender is an adjective describing a person whose gender identity aligns with the sex they were assigned at birth. It functions as the counterpart to 'transgender', which describes people whose identity differs from that assignment. The word derives from Latin roots: 'cis-' means 'on this side of' (as in Cisalpine, on the Roman side of the Alps), while 'gender' comes from Latin genus, meaning kind or category. First appearing in academic writing about gender in the 1990s, the term gained broad currency during the 2010s as public discussion of gender identity expanded. It is now standard vocabulary in medicine, psychology, sociology, journalism, and law, where distinguishing between cisgender and transgender experiences matters for research, healthcare, and policy. The term is neutral in tone and often shortened colloquially to 'cis'. Its usefulness lies in naming the majority experience explicitly rather than treating it as an unmarked default, allowing more precise discussion of how gender shapes different people's lives.

The word cisgender uses the same Latin prefix 'cis-' that gave us 'Cisalpine' — meaning 'on this side of the Alps' — making it the linguistic opposite of 'trans-', as in transalpine and transgender alike.
