Smōke1, n.
(20), n. [A-S. smocca, smēoc, smēc, smyc, from smēocan, to smoke; L. Ger. & D. smook, Dan. smög, H. Ger. schmauch.] 1. The exhalation, visible vapor, or substance that escapes or is expelled from a burning body; — applied especially to the volatile matter expelled from vegetable matter, or wood, coal, peat, and the like, the matter expelled from metallic substances being more generally called fume, or fumes. ☞ The gases of hydrocarbons, raised to a red heat or thereabouts, without a mixture of air enough to produce combustion, disengage their carbon in a fine powder, which floats in the hydrogen: this compound is smoke. The disengaged carbon deposited on solid bodies is soot. 2. That which resembles smoke, as vapor or watery exhalations. ☞ Smoke is sometimes joined with other words, forming self-explaining compounds; as, smoke-cloud, smoke-consuming, smoke-dried, smoke-stained, smoke-wreath, and the like.
