Etymology
Origin of duke
First recorded in 1100–50; Middle English duke, duc, late Old English duc, from Old French duc, dus, dux, from Medieval Latin dux “hereditary ruler of a small state,” Latin: “leader”; see dux; duke def. 5 dukes (in the sense “fists”) of unclear derivation and perhaps of distinct origin
Explanation
A duke is a member of a royal or noble group. In some places, dukes rule over certain regions, while in others duke is just an honorary title. In the U.K., a duke inherits his title from his parents. Prince William, for example, is the Duke of Cambridge, while his father Prince Charles is the Duke of Cornwall and Rothesay. The equivalent title for a woman is duchess. Informally, duke has a very different meaning in the U.S. — if you "duke it out," you have a fight, and to "put up your dukes" means to clench your fists and get ready to punch.
