Praemption

Part of speech: noun

Definitions

1. The archaic right or act of purchasing goods or land before anyone else is allowed to make an offer

3. Refers to the earlier right to buy something ahead of competitors, a claim once recognized in law

Etymology: The root is "emere", Latin for "to buy", which sits inside "praemption" alongside the prefix "prae-", meaning "before". Together they gave a Medieval Latin noun, "praemptio", for buying something ahead of others. The English word keeps that sense of getting first claim to a purchase. The word's main use has always been legal. A right of pre-emption let someone, often a landowner or a ruler's agent, buy goods or property before anyone else could. Its spelling has also shifted: "pre-emption" with a hyphen is the more common modern form, and "praemption" is the older, Latinate version.
