Etymology
Same as Danish rag, Icelandic rogg, Norwegian ragg, Old English adjective raggig and English noun rag, all based on an Indoeuropean root ru ("to rip, tear"), Icelandic rýja(“to rip the wool from sheep, to shear”), Latin ruo(“to rip, dig”) and rutrum(“a shovel”). In older times, wool was not cut or shorn from sheep, but ripped or torn off.
