Did you know?

Is it possible that the origins of the noun rash (meaning “an eruption on the body,” as in “a skin rash”) and the adjective rash (meaning “overly hasty”) are the same? Not so fast! Like many homonyms—“two or more words spelled and pronounced alike but different in meaning”—the two rashes have distinct sources. The noun rash, which first appeared in English in the late 17th century, probably comes ultimately from the Latin verb rādere, meaning “to scrape, scratch, shave.” The adjective rash appears to be about two centuries older, and comes from a Middle English word meaning “active, quick, eager.”
