Pronunciation

  • IPA (Classical): [ˈsɛk.sʊs][1]
  • IPA (Ecclesiastical): [ˈsɛk.sus][1]

Forms

sexus m (genitive sexūs); fourth declension[1]

Etymology

The origin is uncertain.[2][3] The by-form secus, used only as nominative and accusative with adjectives meaning “male” or “female”, looks older, but the earliest texts have only sexus.[2] It is often taken from secāre “to cut”, as “a division”, though how it was formed is unclear.[2][4][5]

Earliest recorded meaning

It is found from Plautus onwards,[2][6] who uses it as a neuter in virile sexus numquam ullum habui, “I never had any male child”.[4]

Semantic evolution

It meant sex or gender, the state of being male or female, as when Cicero says that human beings are classed by sex, whether male or female.[4][5] By metonymy it was all the members of one sex, as virilis sexus “male offspring”.[4] Pliny used it of plants and minerals and of the genitals.[7]

Medieval writers applied it to the supposed sex of the planets.[8] French sexe, Spanish and Portuguese sexo and Romanian sex were borrowed from it,[1] and English sex in the late 14th century, first for males or females as a group.[3]
