 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.

    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.
