From The Collaborative International Dictionary of English v.0.48 [gcide]:
Note: In Great Britain, the term gentleman is applied in a limited sense to those having coats of arms, but who are without a title, and, in this sense, gentlemen hold a middle rank between the nobility and yeomanry. In a more extended sense, it includes every man above the rank of yeoman, comprehending the nobility. In the United States, the term is applied to men of education and good breeding of every occupation.
