Just for added context, here’s a little vocabulary brushup! “Trans” is the shortened version of transgender, meaning someone whose gender assigned at birth doesn’t match up with their gender identity. It comes from the Latin prefix “trans-” meaning “on the other side of.”
“Cis” is the shortened version of cisgender, meaning someone whose gender assigned at birth matches their gender identity. And in Latin, the prefix “cis-” is the antonym of “trans.” Makes total sense, right? So it means “on this side of.”
