What does impetuous mean?
Impetuous describes someone or something that acts with sudden, forceful energy and insufficient deliberation. The word commonly characterizes decisions made in a rush, actions undertaken without careful thought, and personalities marked by impatience or enthusiasm. In contemporary usage, impetuous generally carries a critical or disapproving connotation: an impetuous decision may be understandable or even exciting, but it is often portrayed as premature and potentially harmful. The expression can apply to people, as in an impetuous leader, and to actions, movements, or attitudes, as in an impetuous departure or an impetuous response. Although impetuous and impulsive are closely related, impetuous often emphasizes the physical force or abruptness of the impulse as well as the lack of reflection. It remains a useful word when the goal is to distinguish hurried or emotionally driven behavior from careful, deliberate conduct.

Where does impetuous come from?
Impetuous entered English in the early 17th century from the Latin adjective impetuosus, meaning “rushing, impetuous.” The Latin word was derived from impetus, “impulse, rush, or driving force,” which in turn came from impellere, “to drive forward.” The same Latin root also produced English words such as impetus, impulse, impel, and impeller.
