What does preempt mean?
Preempt means to act before a situation develops, usually in order to prevent a problem or gain an advantage. Someone who preempts an attack takes measures in response to a warning or anticipated threat, while a government or organization that preempts criticism may address concerns before opponents raise them. In another sense, preempt means to claim or decide something before another person or institution can do so. The word is especially common in political, military, legal, and business contexts, where timing and initiative matter. Its usual implication is deliberate and strategic: action is taken early enough to shape events rather than merely react to them. The related adjective preemptive describes an action taken in advance, and the noun preemption refers to the act of preventing or claiming something first.

Where does preempt come from?
Preempt comes from the Latin praeemptus, the past participle of praeemere, meaning “to buy before” or “to purchase in advance.” The prefix prae- means “before,” and emere is the Latin verb “to buy.” The word entered English in the early 17th century, initially in the sense of buying before someone else; its modern sense of forestalling or taking action in advance developed later. Premium, preemption, purchase, and redeem belong to the same broad Latin buying-and-exchanging family of words.
