Related: Aired; airing. n.1c.1300, “invisible gases that make up the atmosphere,” from Old French air “atmosphere, breeze, weather” (12c.), from Latin aerem (nominative aer) “air, lower atmosphere, sky,” from Greek aer (genitive aeros) “air” (related to aenai “to blow, breathe”), of unknown origin, possibly from a base *awer- and thus related to aeirein “to raise” and arteria “windpipe, artery” (see aorta) on notion of “lifting, that which rises.” In Homer mostly “thick air, mist;” later “air” as one of the four elements. Words for “air” in Indo-European languages tend to be associated with wind, brightness, sky. In English, air Replaced native lyft, luft (see loft (n.)).
