  • DID YOU KNOW?

When we borrowed "impetuous" in the late 14th century, we used it of people and their actions. About a hundred years later, we added another sense to describe physical things like wind or storms or seas. (We don't use this second sense much anymore.) The word comes via Middle French from Late Latin "impetuosus," which is from "impetus." Latin "impetus" (which of course gave us our own "impetus," meaning "driving force") essentially means "assault," but it also has figurative senses ranging from "violence" to "ardor." Our "impetuous" has a similar range of meaning, from "violent" to "passionate." It also carries the suggestion of impulsiveness. Often, we put a light touch on the word, as when we refer (somewhat longingly, perhaps) to our "impetuous youth."
