Erode


Definition:

Etch


Definition:

  • (n.) A variant of Eddish.
  • (v. t.) 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.
  • (v. t.) To subject to etching; to draw upon and bite with acid, as a plate of metal.
  • (v. t.) To sketch; to delineate.
  • (v. i.) To practice etching; to make etchings.

Example Sentences:
