body language

Gestures, posture, and other movements made by a person that unconsciously convey his or her feelings or attitude. The term dates from about 1960 and, some authorities believe, originated as a translation of the French langage corporel. Tennis commentators on television often point to a player’s body language, usually inferring a discouraged or negative attitude. The term is also used for performers (actors, singers) who consciously use gesture and movement for their presentations.
