Fox hunting is a traditional sport in which riders on horseback, accompanied by a pack of hounds, chase a fox. The riders and hounds are led by a huntsman who uses a variety of calls to communicate with the hounds. The most common calls used are 'YOICKS' (6 letters), 'HALLO' (5 letters) and 'TALLYHO' (7 letters). These calls are known as the Fox Hunter's Cry and are used to encourage the hounds to pursue the fox.
