The English spoken today in the North has been shaped by the area's history, and some dialects retain features inherited from Old Norse and the local Celtic languages .  Dialects spoken in the North include Cumbrian , Geordie (Newcastle), Mancunian (Manchester), Northumbrian (Northumberland), Pitmatic (Northumberland/County Durham), Scouse (Liverpool) and Tyke (Yorkshire). Linguists have attempted to define a Northern dialect area, corresponding to the area north of a line that begins at the Humber estuary and runs up the River Wharfe and across to the River Lune in north Lancashire.  This area corresponds roughly to the sprachraum of the Old English Northumbrian dialect , although the linguistic elements that defined this area in the past, such as the use of doon instead of down and substitution of an ang sound in words that end - ong ( lang instead of long ), are now prevalent only in the more northern parts of the region. As speech has changed, there is little consensus on what defines a "Northern" accent or dialect.
