IPA: /priˈɛmptər/
KK: /priˈɛmptər/
A person who takes action to prevent something from happening, especially by taking control of land or resources before others can.
The preemptor secured the land before anyone else had a chance to claim it.
Preemptor → It is formed from "pre-" (meaning before) and "emere" (meaning to buy or take). The word refers to someone who takes action before others can, often to secure a position or advantage.
Think of someone who 'takes' ('emere') action 'before' ('pre-') others can — that's why a preemptor acts first.
