词源

Probably from Old French rasche, rache (“skin eruption, rash; (specifically) scabies, scurf”) (obsolete), from racher (“to scrape; to scratch”) (although this is only directly attested later than the noun), from Vulgar Latin *rāsicāre (“to scrape”), from Latin rāsus (“scraped, scratched; shaved”), the perfect passive participle of rādō (“to scrape, scratch; to shave; to rub, smooth; to brush along, graze”). Doublet of rase and raze. Cognates * French rash, rach (“skin eruption, rash”) (rare) (borrowed from English rash) * Italian rasca, raschia (“skin eruption like scabies”) (obsolete) (both borrowed from Old Occitan) * Old Occitan rasca (“skin eruption like scabies”)
