Etymologies

from The American Heritage® Dictionary of the English Language, 4th Edition

[Middle English, from Latin sexus.]

from Wiktionary, Creative Commons Attribution/Share-Alike License

From Middle English sexe, from Old French sexe, from Latin sexus ("gender"). Thought to be connected with Latin seco, secare ("divide, cut") by the concept of division, or 'half' of the race. Akin to section. Meaning "sexual intercourse" first attested 1929 (in writings of D.H. Lawrence).

  • Weirdnet is trying to avoid the definition:

    Sex: activities associated with sexual intercourse

    Then you look for

    Sexual: of or relating to or characterized by sexuality

    And the next step, of course, is

    Sexuality: a property having to do with the functioning of the body

    Hence,

    Sex: "activities associated with the intercourse relating to a property having to do with the functioning of the body".
