Did you know?

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 around 1700, comes by way of French and Vulgar Latin from Latin rasus, the past participle of radere ("to scrape" or "to shave").
