What does usurp mean?
Usurp means to take over or claim power, authority, a position, rights, or an identity without the rightful owner's permission or legal right. Its strongest and most familiar use is political: a ruler, claimant, or rebel may usurp the throne, while a government official may usurp authority. The word carries a formal and condemnatory tone because it implies force, deception, illegitimacy, or an unlawful challenge to an existing order. It can also describe taking someone else's identity or appropriating their rights without authorization. In these contexts, usurp is more pointed than simply take over and more negative than replace, since it stresses the absence of rightful permission. The verb is transitive and takes the thing being seized as its object, as in phrases such as usurp power, usurp the throne, and usurp authority. It is used in both British and American English and is especially common in political writing, history, law, and accounts of rebellion or disputed succession.

Etymology of usurp
The word entered English through Old French usurper, which was borrowed from Latin ūsūrpāre, a verb meaning to take possession of, seize, or appropriate. Latin ūsūrpāre is generally associated with ūsus, “use,” although the precise historical development is not fully transparent. English derivatives include usurpation and usurper; usage and usual also reflect the broader Latin lineage connected with ūsus. The modern sense of illegally taking over power or authority developed from the word's earlier legal and political associations with seizing property or position by force or fraud.
