viceroy

A viceroy is a regal official who runs a country, colony, or city province (or state) in the name of and as representative of the monarch. The term derives from the Latin prefix vice-, meaning "in the place of" and the French word roi, meaning king. A viceroy's province or larger territory may be called a viceroyalty. The adjective form is viceregal, less often viceroyal. A vicereine is a woman in a viceregal position, or a viceroy's wife.
