Smoke \Smoke\, n. [AS. smoca, fr. sme['o]can to smoke; akin to
   LG. & D. smook smoke, Dan. sm["o]g, G. schmauch, and perh. to
   Gr. ??? to burn in a smoldering fire; cf. Lith. smaugti to
   choke.]
   1. The visible exhalation, vapor, or substance that escapes,
      or expelled, from a burning body, especially from burning
      vegetable matter, as wood, coal, peat, or the like.

         thereabouts, without a mixture of air enough to produce
         combustion, disengage their carbon in a fine powder,
         forming smoke. The disengaged carbon when deposited on
         solid bodies is soot.

   2. That which resembles smoke; a vapor; a mist.

   3. Anything unsubstantial, as idle talk. --Shak.

   4. The act of smoking, esp. of smoking tobacco; as, to have a
      smoke. [Colloq.]

   Note: Smoke is sometimes joined with other word. forming
         self-explaining compounds; as, smoke-consuming,
         smoke-dried, smoke-stained, etc.
