The Mounth is the broad upland in northeast Scotland between the Highland Boundary and the River Dee. It is invariably referred to as The Mounth and pronounced munth. The name is derived from Scottish Gaelic monadh which is akin to the Welsh mynydd, and may be of Pictish origin, meaning simply upland. Traditionally the people of northern Scotland did not consider the Grampians to be a single range, but several, and these were known as the Mounths. The ranges to the north-west are known as the Monadh Liath and the Monadh Ruadh (now called The Cairngorms), meaning the Grey Mounth and the Red Mounth.
