1382, probably representing a merger of O.N. steina "to paint" and an aphetic form of M.E. disteynen "to discolor or stain," from O.Fr. desteign-, stem of desteindre "to remove the color," from des- (from L. dis- "remove") + O.Fr. teindre "to dye," from L. tingere (see tincture). The noun is from 1563. Stained glass is attested from 1791.
