In modern parlance, a gentleman (from gentle + man, translating the Old French gentilz hom) is any man of good, courteous conduct.

The modern female equivalent is lady.
Of Gentlemen, Scholars, Warrior, Poets, and Priests. 1  Few words create such a vivid, complex, controversial, and individualized interpretation within the English language like the words Gentleman and Chivalry. Everyone seems to have their own idea of what a gentleman is, or at least what he should be. Images of an elegant well-dressed man with impeccable manners, drinking only the finest single malt scotch from French perfume bottles the size of a milk gallon comes to mind.
