1. To be set over for the exercise of authority; to direct, control and govern, as the chief officer. A man may preside over a nation or province; or he may preside over a senate, or a meeting of citizens. The word is used chiefly in the latter sense. We say, a man presides over the senate with dignity. Hence it usually denotes temporary superintendence and government.
