The Cumbrian dialect is a local Northern English dialect in decline, spoken in Cumbria (including historic Cumberland and Westmorland) and surrounding northern England, not to be confused with the area's extinct Celtic language, Cumbric. Barrow-in-Furness (within the historic boundaries of Lancashire) has a similar accent to much of Lancashire whilst the northern parts of Cumbria have a more North-East English sound to them. Whilst clearly being a Northern English accent, it shares much vocabulary with Scots. A Cumbrian Dictionary of Dialect, Tradition and Folklore by William Rollinson exists, as well a more contemporary and lighthearted Cumbrian Dictionary and Phrase Book.
Despite the modern county being created only in 1974 from the counties of Cumberland, Westmorland and north Lancashire and parts of Yorkshire, Cumbria is an ancient land. Before the arrival of the Romans the area was the home of the Carvetii tribe, which was later assimilated to the larger Brigantes tribe. These people would have spoken Brythonic, which developed into Old Welsh, but around the 5th century AD, when Cumbria was the centre of the kingdom of Rheged, the language spoken in northern England and southern Scotland from Lancashire and Yorkshire to Strathclyde had developed into a dialect of Brythonic known as Cumbric (the scarcity of linguistic evidence, however, means that Cumbric's distinctness from Old Welsh is more deduced than proven). Remnants of Brythonic and Cumbric are most often seen in place names, in elements such as caer 'fort' as in Carlisle, pen 'hill' as in Penrith and craig 'crag, rock' as in High Crag.
