What does preemption mean?
Preemption is the practice or legal principle of acting before others to prevent a development or obtain an advantage. It can mean forestalling an event, such as a rival's takeover or a threatened disruption, and it can also refer to acquiring property or a contractual opportunity in preference to other interested parties. In military strategy, preemption means striking first to reduce an opponent's ability to respond. The word is especially common in legal and business contexts, where “right of preemption” and similar expressions describe a priority opportunity. Its associations are generally strategic and protective: preemption depends on anticipation and decisive early action rather than waiting after a problem has developed.

Where does preemption come from?
The word comes through French préemption from Latin praeemptio, a noun formed from praeemptus, “foretaken” or “purchased beforehand.” The underlying Latin verb praeemere combined prae-, meaning “before,” with emere, “to buy,” giving the sense of buying or taking something before someone else. English developed the related verb preempt and its adjective and adverb forms.
