"‘Trans’ [...] is an umbrella term that describes people whose gender identity (their personal sense of their own gender) varies from, does not sit comfortably with, or is different from, the biological sex recorded on their birth certificate based on the appearance of their external genitalia. The standard view of how sex and gender manifest in the world is as follows. Babies born with observable penises are recorded as male, referred to and raised as boys, and as adults are men; babies born with observable vulvas are recorded as female, referred to and raised as girls, and as adults are women. To be trans is, on some level, to feel that this standardized relationship between one’s genitalia at birth and the assignment of one of two fixed gender identities that are supposed to accurately reflect your feelings about your own body has been interrupted. How the person who experiences this interruption reacts to it can vary hugely – which is why ‘trans’ is a catch-all word for a diverse range of identities and experiences."
