What does impellent mean?
Impellent is a formal and relatively uncommon word with two related uses. As an adjective, it describes a force, motive, or need that drives someone to act: an impellent demand for reform can make a government change course. As a noun, an impellent is the pressure or incentive behind action, such as ambition, necessity, or moral conviction. The word has a strongly directional sense, suggesting that something is being pushed or urged forward rather than merely attracting attention. Because it sounds emphatic and literary, impellent often appears in essays, political writing, and formal descriptions of motivation, where it conveys urgency and active pressure. It is useful when the aim is to name the force compelling a decision rather than the decision itself. Although its vocabulary is uncommon in everyday speech, the word is precise: an impellent is not simply interesting or persuasive but effective in moving a person or institution onward.

Where does impellent come from?
The adjective developed in the early 17th century from the Latin present participle impellentem, meaning “driving forward,” from impellere, “to drive or force onward.” The noun meaning “something that impels” developed in the early 19th century. Latin impellere combines in-, meaning “into” or “on,” with pellere, “to drive,” the same root found in expel, propel, and compulsion.
