The unique way in which Geordies and Northumbrians pronounce certain words is also often Anglo-Saxon in origin. Thus Geordie words like Dede, Coo, Cloot, Hoos, Wrang, Strang and Lang are in fact the original Anglo-Saxon pronounciations for Dead, Cow, Clout, House, Wrong, Strong and Long.
My dad was sitting in a bar with an Welsh, Scot and Australian and with all the different words they started joking "we're all speaking English right??"
