    Definition of air by GCIDE Dictionary

    air


    1. Air ( âr ), n. [OE. air, eir, F. air, L. aër, fr. Gr. ἀήρ, air, mist, for ἀϝηρ, fr. root ἀϝ to blow, breathe, probably akin to E. wind. In sense 10 the French has taking a meaning fr. It. aria atmosphere, air, fr. the same Latin word; and in senses 11, 12, 13 the French meaning is either fr. L. aria, or due to confusion with F. aire, in an older sense of origin, descent. Cf. Aëry, Debonair, Malaria, Wind.]
      1. The fluid which we breathe, and which surrounds the earth; the atmosphere. It is invisible, inodorous, insipid, transparent, compressible, elastic, and ponderable.

      ☞ By the ancient philosophers, air was regarded as an element; but modern science has shown that it is essentially a mixture of oxygen and nitrogen, with a small amount of carbon dioxide, the average proportions being, by volume: oxygen, 20.96 per cent.; nitrogen, 79.00 per cent.; carbon dioxide, 0.04 per cent. These proportions are subject to a very slight variability. Air also always contains some vapor of water.

      2. Symbolically: Something unsubstantial, light, or volatile. “Charm ache with air.” Shak.

      He was still all air and fire.
      [Air and fire being the finer and quicker elements as opposed to earth and water.] Macaulay.

      3. A particular state of the atmosphere, as respects heat, cold, moisture, etc., or as affecting the sensations; as, “a smoky air, a damp air, the morning air, etc.”

      4. Any aëriform body; a gas; as, “oxygen was formerly called vital air”. [Obs.]

      10. ( Mus. ) A musical idea, or motive, rhythmically developed in consecutive single tones, so as to form a symmetrical and balanced whole, which may be sung by a single voice to the stanzas of a hymn or song, or even to plain prose, or played upon an instrument; a melody; a tune; an aria. In harmonized chorals, psalmody, part songs, etc., the part which bears the tune or melody -- in modern harmony usually the upper part -- is sometimes called the air.

      11. The peculiar look, appearance, and bearing of a person; mien; demeanor; as, “the air of a youth; a heavy air; a lofty air.” “His very air.” Shak.

      12. Peculiar appearance; apparent character; semblance; manner; style.

      12. pl. An artificial or affected manner; show of pride or vanity; haughtiness; as, “it is said of a person, he puts on airs”. Thackeray.



      14. ( Paint. ) The representation or reproduction of the effect of the atmospheric medium through which every object in nature is viewed. New Am. Cyc. Carriage; attitude; action; movement; as, “the head of that portrait has a good air”. Fairholt.
