   D. bosch, OHG. busc, G. busch, Icel. b[=u]skr, b[=u]ski, Dan.
   busk, Sw. buske, and also to LL. boscus, buscus, Pr. bosc,
   It. bosco, Sp. & Pg. bosque, F. bois, OF. bos. Whether the
   LL. or G. form is the original is uncertain; if the LL., it
   is perh. from the same source as E. box a case. Cf. {Ambush},
   {Boscage}, {Bouquet}, {Box} a case.]
   1. A thicket, or place abounding in trees or shrubs; a wild

   Note: This was the original sense of the word, as in the

         this sense it is extensively used in the British
         colonies, especially at the Cape of Good Hope, and also
         in Australia and Canada; as, to live or settle in the
         bush.

   3. A shrub cut off, or a shrublike branch of a tree; as,
      bushes to support pea vines.

   4. A shrub or branch, properly, a branch of ivy (as sacred to
      Bacchus), hung out at vintners' doors, or as a tavern
      sign; hence, a tavern sign, and symbolically, the tavern
      itself.

            true that a good play needs no epilogue. --Shak.

   {To beat about the bush}, to approach anything in a
