" 'Homosexual' is a barbarously hybrid word, and I claim no responsibility for it." [H. Havelock Ellis, "Studies in Psychology," 1897]The noun is first recorded 1912 in Eng., 1907 in French. In technical use, either male or female; but in non-technical use almost always male. Slang shortened form homo first attested 1929. The alternative homophile (1960) was coined in ref. to the homosexual regarded as a person of a particular social group, rather than a sexual abnormality. Homo-erotic first recorded 1916; homophobia is from 1969.
