impel

Sometimes, an inner feeling, a strong desire, or a real need can impel you to act. Think of a sudden rush of emotion that makes you speak up, or the powerful instinct that leads a mother bear to protect her cubs. It is not usually a physical push, but a strong force within.

The word suggests more than simply wanting to do something; it means being driven by something such as duty, fear, love, or desperation. A detective might be impelled to solve a case by a sense of justice, and a refugee might be impelled to flee their homeland by danger. You can also use impel for things that physically drive something else forward, like wind impelling a sailboat.

To impel someone or something means to drive or strongly urge them toward a particular course of action. It suggests a powerful motivating force, internal or external, that causes movement or action. Unlike simply telling someone to do something, impel suggests strong pressure or motivation.

The word comes from Latin: "im-" meaning "into" and "pellere" meaning "to drive." That idea of forceful movement helps explain how the word is used. You might read that "a desire for knowledge impelled him to study late into the night," which shows an inner drive behind his actions. Or you could say that "the rising floodwaters impelled residents to evacuate their homes," which shows an outside force causing people to act.

Impel is not limited to people; it can also be used with inanimate objects. "The wind impelled the ship forward" describes a physical push. Even in these cases, there is often a sense of strong forward movement.

It is a fairly formal word, often found in literature and serious writing where nuance matters. It is usually stronger than "encourage" or "motivate," because it suggests pressure that is hard to resist. So when something impels you, it does not just influence your decision; it drives you to act.
