| 词根词缀 | 词源： 1. air (1) 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. 2. air (2) "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. 3. air (3) "melody, tune," 1580s, from It. aria (see aria). 词根记忆： n. 空气;(复数)神气vt.(使)通风;晾干Birds fly high in the air.鸟在高空中飞翔. |
