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.
