Kentish dialect (Old English) in the context of "Northumbrian Old English"

West Saxon is the term applied to the two different dialects Early West Saxon and Late West Saxon with West Saxon being one of the four distinct regional 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. Due to the Saxons' establishment as a politically dominant force in the Old English period, the West Saxon dialects became the strongest dialects in Old English manuscript writing.
