Etymology

The word "heterosexual" combines the Greek prefix "hetero-" (meaning "other" or "different") with the Latin-derived root "sexual" (relating to biological sex or attraction). The term emerged in the late 19th century within medical and psychological discourse to describe attraction to the opposite sex, contrasting with "homosexual" (same-sex attraction). The morphemes reflect a scientific approach to categorizing human sexuality, with "hetero-" emphasizing difference and "sexual" anchoring the term in biological and romantic contexts.
