Why “impetus” is a great word
The initial force or stimulus that sets a process in motion or accelerates its momentum. From the Latin impetus ("a rushing upon, an attack, assault, onset"), from impetere ("to attack"), combining in- ("upon") and petere ("to seek, rush at"), first recorded in English use 1650–60. Unlike an "incentive" (an external carrot) or "momentum" (the subsequent roll of the boulder), impetus is the originating thrust—the spark in the dry tinder, the first domino tilting, the sudden silence that births a confession. It exists in the fragile, decisive moment when potential becomes kinetic, and the world is jarred from its stillness.
Etymology
Borrowed from Latin impetus (“a rushing upon, an attack, assault, onset”), from impetō (“to rush upon, attack”), from in- (“upon”) + petō (“to seek, fall upon”).
