Word Origin & History

vapor 
c.1374, from Anglo-Fr. vapour, from L. vaporem (nom. vapor) "exhalation, steam, heat," of unknown origin. Vapors "fit of fainting, hysteria, etc." is 1662, from medieval notion of "exhalations" from the stomach or other organs affecting the brain. Vaporize (v.) is attested from 1634, originally "to smoke tobacco," later "to convert into vapor" (1803), and "to spray with fine mist" (1900).
