The definition of an adjective is a part of speech that is used to describe a noun. Red, tall, better and fast are all examples of adjectives.
In 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.
Noun. 1  A person whom one does not know; a person who is neither a friend nor an acquaintance. quotations â¼ That gentleman is a stranger to me. Children are taught not to talk to strangers. 1893, Walter Besant, The Ivory Gate, chapter III: In former days every tavern of repute kept such a room for its own select circle, a club, or society, of habituÃ©s, who met every evening, for a pipe and a cheerful glass.
