Rasp \Rasp\, n. [OE. raspe, OF. raspe, F. r[^a]pe. See {Rasp},
   v.]
   1. A coarse file, on which the cutting prominences are
      distinct points raised by the oblique stroke of a sharp
      punch, instead of lines raised by a chisel, as on the true
      file.

   2. The raspberry. [Obs.] ``Set sorrel amongst rasps, and the
      rasps will be smaller.'' --Bacon.

   {Rasp palm} (Bot.), a Brazilian palm tree ({Iriartea
      exorhiza}) which has strong a["e]rial roots like a screw
      pine. The roots have a hard, rough surface, and are used
      by the natives for graters and rasps, whence the common
      name.
