Regnant means reigning or ruling; exercising power or authority. It specifically describes someone who is currently holding the position of ruler. Think of a king or queen actively sitting on the throne – they are regnant. It's a more formal and slightly archaic way to say 'reigning.' Unlike 'regent,' a regnant ruler has full and legitimate authority. It's like being the captain of the ship while it's sailing smoothly, not just during a storm.
