Gentleman
In modern parlance, the term gentleman (from Latin gentilis, belonging to a race or gens, and man, the Italian gentil uomo or gentiluomo, the French gentilhomme, the Spanish gentilhombre, and the Portuguese homem gentil) refers to any man of good, courteous conduct. It may also refer to all men collectively, 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.
