tragico-, tragi-, trago-, trag- (Greek: goat).

Pertaining to a "tragedy" that refers to a play or other serious literary work having an unhappy ending. Literally, "goat song", supposedly because the actors or singers in Greek tragedies were originally dressed in goatskins to represent satyrs, and thereby became actors in satyric drama from which "tragedy" was later developed. Another theory is that a goat may have been the prize given to an actor for the best performance in a Greek play.
