Tobacco \To*bac"co\, n. [Sp. tabaco, fr. the Indian tabaco the
   tube or pipe in which the Indians or Caribbees smoked this
   plant. Some derive the word from Tabaco, a province of
   Yucatan, where it was said to be first found by the
   Spaniards; others from the island of Tobago, one of the
   Caribbees. But these derivations are very doubtful.]
   1. (Bot.) An American plant (Nicotiana Tabacum) of the
      Nightshade family, much used for smoking and chewing, and

      acrid taste.

         to some unrelated plants, as Indian tobacco (Nicotiana
