The Lammermuir Hills, usually simply called the Lammermuirs (An Lomair Mòr in Gaelic) (occasionally anglicised Lammermoors), in southern Scotland, form a natural boundary between Lothian and the Scottish Borders.
The hills are nowhere especially high, the highest points being Meikle Says Law at 535 m (1,755 ft) and the Lammer Law at 528 m (1,732 ft), but steep gradients, exposure to the elements and a lack of natural passes combine to form a formidable barrier to communications between Edinburgh and the Borders.
The hills are crossed by only one major road (the A68), which crosses the shoulder of Soutra Hill between Lauder and Pathhead, and is frequently closed by snow in winter. The main road linking Edinburgh to England (the A1) avoids the hills by following a circuitous route around the coast
The name Lammermuir literally means "lambs' moor" or "moorland of the lambs" from the Old English genitive plural lambra "of lambs" and the noun mor "moorland", "swamp", "waste ground". Early forms include Lombormore, Lambremore, Lambermora and Lambirmor. Another place-name with the element lambra is Lamberton.
