Word Origin & History

1551, "coarse fabric," of Scand. origin, cf. Norw. dial. rugga "coarse coverlet," from O.N. rogg "shaggy tuft," probably related to rag and perhaps also rough. Sense evolved to "coverlet, wrap" (1591), then "mat for the floor" (1808). Meaning "toupee" is theater slang from 1940. Cut a rug "dance" is
slang first attested 1942. To sweep (something) under the rug in the fig. sense is from 1961. Rug-rat "baby, child" is from 1968.
