Word Origin & History

rash
c.1300, "nimble, quick, vigorous," a Scottish and northern word, perhaps from O.E. -ræsc (cf. ligræsc "flash of lightning"), from P.Gmc. *raskuz (cf. M.L.G. rasch, M.Du. rasc "quick, swift," Ger. rasch "quick, fast"). Related to O.E. horsc "quick-witted." Sense of "reckless, impetuous, heedless
of consequences" is attested from 1509.

rash
"red spots on skin," 1709, perhaps from Fr. rache "a sore," from O.Fr. rache "ringworm," from V.L. *rasicare "to scrape" (cf. O.Prov. rascar, Sp. rascar "to scrape, scratch," It. raschina "itch"), from L. rasus "scraped," pp. of radere "to scrape" (see raze). The connecting
notion is of itching. Sense of "any sudden outbreak or proliferation" first recorded 1820.
