Etch \Etch\, v. t. [imp. & p. p. {Etched}; p. pr. & vb. n.
   {Etching}.] [D. etsen, G. ["a]tzen to feed, corrode, etch.
   MHG. etzen, causative of ezzen to eat, G. essen ??. See

   1. To produce, as figures or designs, on mental, glass, or
      the like, by means of lines or strokes eaten in or
      corroded by means of some strong acid.

   Note: The plate is first covered with varnish, or some other
         ground capable of resisting the acid, and this is then
         scored or scratched with a needle, or similar
         instrument, so as to form the drawing; the plate is
         then covered with acid, which corrodes the metal in the
         lines thus laid bare.

   2. To subject to etching; to draw upon and bite with acid, as
      a plate of metal.

            I was etching a plate at the beginning of 1875.

   3. To sketch; to delineate. [R.]

            There are many empty terms to be found in some
            learned writes, to which they had recourse to etch
            out their system.                     --Locke.
