The Kingdom of Mercia, East Anglia, and Mercian Kingdoms

Linguists think that the people within these two kingdoms spoke a common dialect, which is usually called Mercian. As the Angles spread westward from East Anglia, they took their dialect with them. Northumbria was located north of the River Humber and had its own distinct dialect. But in situations where all of the Anglian dialects are the same, linguists will sometimes lump them together and refer to them collectively as theAnglian dialect.
