A gyron is a triangular heraldic ordinary having an angle at the fess point and the opposite side at the edge of the escutcheon. A shield divided into gyrons is called gyronny, the default is typically of eight if no number of gyrons is specified. The word gyron is derived from Old French giron, meaning 'gusset'. Another term for a single gyron is esquire.
