exert

Exert is a verb meaning to apply or bring to bear a force, influence, or effort. It is used to describe physically applying a force to an object, as well as using influence, authority, or resources to achieve a result.

Etymology traces exert to Old French exercer, from Latin exercere, meaning to exercise or practise. The sense of applying effort or force developed through the notion of exercising power or activity.

Grammatically, exert is transitive and follows standard verb forms: exert, exerts, exerted, exerting. It takes a direct object, as in “exert pressure,” “exert influence,” or “exert force.” The reflexive form “exert oneself” means to make a strenuous effort. The related noun is exertion, and the adjective exertional is used in some medical or athletic contexts.

Usage examples illustrate its range. In physics or mechanics, one speaks of a force that exerts on an object, or a field that exerts attraction. In social or political contexts, a person may exert authority or influence. In everyday language, people speak of exerting effort to complete tasks, or of exerting oneself during strenuous activity. The term thus covers physical, social, and psychological applications, connecting the act of applying something to the result achieved.
