Etching \Etch"ing\, n.
   1. The act, art, or practice of engraving by means of acid
      which eats away lines or surfaces left unprotected in
      metal, glass, or the like. See {Etch}, v. t.

   2. A design carried out by means of the above process; a
      pattern on metal, glass, etc., produced by etching.

   3. An impression on paper, parchment, or other material,
      taken in ink from an etched plate.

   {Etching figures} (Min.), markings produced on the face of a
      crystal by the action of an appropriate solvent. They have
      usually a definite form, and are important as revealing
      the molecular structure.

      lines are drawn in the ground or varnish in etching.

   {Etching stitch} (Needlework), a stitch used outline

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
   {Eat}.]
   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.
                                                  --Hamerton.

   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.
