Cisgender (often shorted to cis) is a term that refers to anyone whose gender identity aligns with their sex assigned at birth. This term applies to those who fully or more closely identify as their assigned sex while simultaneously rejecting the term transgender. The term cisgender is the opposite of the word transgender.
Cisgender may sometimes be referred to as cissexual (opposite of transsexual, not to be confused with a sexual orientation).
"Cis" comes from the Latin prefix meaning "on the same side", as in the cis-trans distinction in chemistry. The origin of the term in reference to gender is credited to Carl Buijs who proposed the term in 1995, and although the word had been used on the internet before 1995, Carl Buijs is the first recorded source to define the term. It's possible that the term was independently coined elsewhere.

- I grew up in a family with a cisgender and heterosexually identified mother and father of the same race (White) who had 2 children when they were well into their late 20s and early 30s and after they legally married with the full support of both their families.

- In a very real and measurable way, cisgender identity is no longer unmarked, universal, or assumed. It is denoted, limited, and in conversation with trans identities—or at least we're moving in that direction.
