AIR Air, n. Etym: [OE. air, eir, F. air, L. aër, fr. Gr. 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. A, 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.
Note: 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. Macaulay . [Air and fire being the finer and quicker elements as opposed to earth and water.]
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.]
5. Air in motion; a light breeze; a gentle wind. Let vernal airs through trembling osiers play. Pope.
