LIEUTENANT. This word has now a narrower meaning than it formerly had; its true meaning is a deputy, a substitute, from the French lieu, (place or post) and tenant (holder). Among civil officers we have lieutenant governors, who in certain cases perform the duties of governors; (vide, the names of the several states,) lieutenants of police, &c. Among military men, lieutenant general was formerly the title of a commanding general, but now it signifies the degree above major general. Lieutenant colonel, is the officer between the colonel and the major. Lieutenant simply signifies the officer next below a captain. In the navy, a lieutenant is the second officer next in command to the captain of a ship.
