Gentleman

n modern parlance, a gentleman (from gentle + man, translating the Old French gentilz hom) is any man of good, courteous conduct. A gentleman may also simply be a polite term for any man, as in indications of gender-separated facilities, or as a sign of the speaker's own courtesy when addressing others. The modern female equivalent is lady.

Originally, a gentleman was a man of the lowest rank of the English gentry, standing below an esquire and above a yeoman. By definition, this category included the younger sons of the younger sons of peers and the younger sons of baronets, knights, and esquires in perpetual succession, and thus the term captures the common denominator of gentility (and often armigerousness) shared by both constituents of the English aristocracy: the peerage and the gentry. In this sense, it corresponds to the French gentilhomme ("nobleman"), which in Great Britain, has long meant only the peerage. Maurice Keen points to the category of "gentlemen" in this context as thus constituting "the nearest contemporary English equivalent of the noblesse of France". The notion of "gentlemen" as encapsulating the members of the hereditary ruling class was what the rebels under John Ball in the 14th century meant when they repeated:

When Adam delved and Eve span,
Who was then the gentleman?
