Root Explanation

Impetus is derived from the Latin "impetus" (meaning attack or force), which comes from "impetere" (meaning to attack or to rush against), formed by the prefix "in-" (meaning into) and "petere" (meaning to seek or to rush). The word describes a force that drives something forward or an impetus that propels action.

Memory Tip

Think of a force that 'rushes into' action — 'in-' means into, and 'petere' means to seek or rush. This helps you remember that 'impetus' refers to a driving force or motivation.
