The act of taking away someone's property or rights, usually by a government for public use.
The government announced the expropriation of land for the new highway.
Expropriation → It is formed from "ex-" (meaning out of or from) and "propriare" (meaning to make one's own). The word refers to the act of taking property away from its owner, thus making it the property of another, typically the state.
Think of 'taking something out of someone's ownership' — 'ex-' means out of, and 'propriare' means to make one's own.
