Did You Know?

Adjective

The earliest known uses of "rash" (then spelled "rasch") occur in a northern dialect of 15th-century Middle English. Its earlier origins are not known for sure, though it is clearly related to a number of similar words in the Germanic languages, including Old High German rasc ("fast, hurried, strong, clever"), Old Norse "röskr" ("brave, vigorous"), and Middle Dutch "rasch" ("quick, nimble, agile, vigorous"). It is not, however, related to the English noun "rash" ("an eruption on the body," as in a "skin rash"). The noun "rash," which first appeared in English in the 1700s, comes by way of French and Vulgar Latin from Latin rasus, the past participle of "radere" ("to scrape" or "to shave").
