Cisgender (often abbreviated to simply cis) is a term for people whose gender identity matches the sex that they were assigned at birth. Cisgender may also be defined as those who have "a gender identity or perform a gender role society considers appropriate for one's sex". It is the opposite of the term transgender.
“ Trans folks are often expected to embrace a narrative that makes cis people comfortable--something simple and linear that upholds their binary understanding of gender transition. ”
