Marks the first known published use of term “homosexuality” by Károly Mária Kertbeny, a German-Hungarian advocate, in a letter to Karl Ulrichs. The neologism “heterosexuality” came later. The word homosexual is a Greek and Latin hybrid. The prefix homo is not from the Latin homo “man” but from the Greek homos, which means “the same,” thus giving the word homosexual its definition of “same sex relationship.” Homosexual is not as widely accepted because it emphasizes the word as just a sexuality but not as a cultural and social attitude which gay and lesbians have and it has the overtones of pathology derived from its original usage to define it in medical terminology. Gay generally refers to male homosexuality, but may be used in a broader sense to refer to all LGBT people. In the context of sexuality, Lesbian refers only to female homosexuality. The word Lesbian is derived from the name of the Greek island Lesbos, where the poet Sappho wrote about her emotional relationships with young women.
