More example sentences

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—this second sense we don't use much anymore. The word comes via Anglo-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."
