語源
英語の原文（Wiktionary）
From Middle English sexe (“sex [distinction between male and female] and gender”), from Old French sexe (“genitals; gender”), from Latin sexus (“gender; gender traits; males or females; genitals”), from Proto-Italic *seksus, from Proto-Indo-European *séksus, from *sek- (“to cut, cut off, sever”), thus meaning "section, division" (into male and female). Displaced native Old English hād (“sex, gender”). Usage for women influenced by Middle French le sexe (“women”) (attested in 1580). Usage for third and additional sexes calqued from French troisième sexe, referring to masculine women in 1817 and homosexuals in 1847.
