History

Etymology

From Latin cis (“on this side (of), on the near or same side”). Doublet of he, it, here, hither, and hence.

Clipping of cisgender or cissexual, ultimately from Latin cis.

Likely originates from the false etymology asserting that cis is an initialism standing for comfortable in skin.
