## AI Etymology
impetuous comes from Old French impetueus, from Late Latin impetuosus, from Latin impetus ('attack, impulse'), from impetere ('to attack'), from in- ('toward') + petere ('to seek, rush at'). Morphologically, the prefixed shape matters: the initial element belongs to the recorded formation and helps explain the modern form's surface analysis. In present English, the adjective sense is "acting hastily and without thought; impulsive", so the historical development ends in a clearly identifiable modern dictionary use. The same base also appears in related forms such as impetus, petition, compete, and appetite, and in derivatives such as impetuously, impetuosity, and impetuousness. Its semantic neighborhood includes impulsive, rash, hasty, and reckless, which helps locate the modern sense without adding a separate etymological claim. The named historical forms include Latin impetuosus and Latin petere.
