Plinlimmon, or PLYNLIMMON, a large mountain-mass (2469 feet) of Wales with three summits, on the boundary between Montgomery and Cardigan, 10 miles W. of Llanidloes. The name is said to be a corruption of a Celtic word signifying Five Rivers, five rivers having their sources on its slopes; one is the Severn, another the Wye.
