Sense: noun/1
A regent is a temporary substitute for a monarch — they hold power only until the rightful king or queen can take over. A monarch (king or queen) rules for life and inherits the position, whereas a regent is appointed, not born into the role. Ruler is the broadest term: it covers any person who governs a country, whether a monarch, a president, or a dictator. Sovereign is similar to monarch but emphasises supreme and independent authority; a regent never holds sovereignty, only the temporary exercise of power. Governor refers to the head of a region or colony, not a substitute for the monarch. For example, a governor runs a province on behalf of a central government, while a regent runs the entire kingdom on behalf of the absent monarch.

Etymology
From Latin 'regens' (present participle of 'regere' — to rule, direct, or guide), via Middle English. The word entered English in the 1400s, first used as an adjective meaning 'ruling'. The noun sense referring to a temporary monarch appeared soon after, and the university-board sense developed in 19th-century America.
