Etymology: Teesdale is the valley of the River Tees in northern England, and its name is simply a compound of two Old English-derived parts: "Tees," the name of the river, and "dale," meaning a valley. The river's own name is the older and more mysterious element; "dale" is an ordinary English word for a valley, familiar from many place names across the north of England. So the name works like a description: the valley belonging to the Tees. Many English valleys were named this way, with the river given first and the landform second, which is why the pattern appears so often in northern place names.
