Etymology 1

    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).

    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. First used by Lord Byron and others in English in reference to Catholic clergy. Usage for sexual intercourse first attested in 1899 (in the writings of H. G. Wells).[1]

        If, in fact, in L. funebris there is no sex marker on the song elements themselves, then a young bird must be able to sex its tutor. The same is true if the individuals were predisposed to produce the total vocabulary of any population, or of both sexes in their own population, and then under experience had to suppress a sex-specific subset of that repertoire [7]. It seems unrealistic to assume the reverse, that a parent bird can sex by some hidden cues newly hatched sexually monomorphic offspring and direct its own vocabulary to consexual young only.
