c. 1300, 'invisible gases that surround the earth,' from Old French air 'atmosphere, breeze, weather' (12c.), from Latin aer 'air, lower atmosphere, sky,' from Greek aēr (genitive aeros) 'mist, haze, clouds,' later 'atmosphere' (perhaps related to aenai 'to blow, breathe'), which is of unknown origin. It is possibly from a PIE *awer- and thus related to aeirein 'to raise' and arteria 'windpipe, artery' (see aorta) on notion of 'lifting, suspended, that which rises,' but this has phonetic difficulties.
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.

1590s, 'manner, appearance' (as in an air of mystery); 1650s, 'assumed manner, affected appearance' (especially in phrase put on airs, 1781), from French air 'look, appearance, mien, bearing, tone' (Old French aire 'reality, essence, nature, descent, extraction' (12c.); compare debonair), which is perhaps from Latin ager 'place, field, productive land' (from PIE root *agro- 'field') on notion of 'place of origin.'
But some French sources connect this Old French word with the source of air (n.1), and it also is possible these senses in English developed from or were influenced by air (n.1); compare sense development of atmosphere and Latin spiritus 'breath, breeze,' also 'high spirit, pride,' and the extended senses of anima.
air (n.3)
'melody, tune, connected rhythmic succession of distinct musical sounds,' 1580s, nativized from Italian aria (see aria), perhaps via French.
