West Saxon was one of four distinct dialects of Old English. The three others were Kentish, Mercian and Northumbrian (the latter two were similar and are known as the Anglian dialects). West Saxon was the language of the kingdom of Wessex, and was the basis for successive widely used literary forms of Old English: the Early West Saxon of Alfred the Great's time, and the Late West Saxon of the late 10th and 11th centuries.
