Word Origin & History

air
c.1300, "invisible gases that make up the atmosphere," from O.Fr. air, from L. ærem (nom. ær), from Gk. aer (gen. æros) "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. Replaced native lyft, luft (see loft). The verb meaning "to expose to open air" is first recorded 1520s. Broadcasting sense (e.g. on the air) first recorded 1927. To give (someone) the air "dismiss" is from 1900. Air pollution is attested by 1870.

air
"assumed manner, affected appearance," 1650s (especially in phrase put on airs, 1781), perhaps via Fr. air "look, appearance, mien, bearing, tone" (O.Fr. aire "reality, essence, nature, descent, extraction" 12c.; cf. debonair), from L. ager "place, field" (see
acre) on notion of "place of origin." Air in the sense of "manner, appearance" (e.g. an air of mystery) is attested in English from 1590s, an independent adoption of Fr. air. But perhaps these senses in English also developed from or were infl. by air (1); cf. L. spiritus "breath, breeze," also "high spirit, pride," and the extended senses of anima.

air
"melody, tune," 1580s, from It. aria (see aria).

Air definition


the atmosphere, as opposed to the higher regions of the sky (1 Thess. 4:17; Rev. 9:2; 16:17). This word occurs once as the rendering of the Hebrew _ruah_ (Job 41:16); elsewhere it is the rendering of _shamaiyim_, usually translated "heavens." The expression "to speak into the air" (1 Cor. 14:9) is a proverb denoting to speak in vain, as to "beat the air" (1 Cor. 9:26) denotes to labour in vain.
