Modern Scots comprises the varieties of (Lowland) Scots traditionally spoken in Lowland Scotland and parts of Ulster from 1700.
Throughout its history, Modern Scots has been undergoing a process of language attrition, whereby successive generations of speakers have adopted more and more features from Standard English. This process of language contact has accelerated rapidly since widespread access to mass media in English and increased population mobility became available after the Second World War. It has recently taken on the nature of wholesale language shift towards Scottish English, sometimes also termed language change, convergence or merger. By the end of the twentieth century Scots was at an advanced stage of language death over much of Lowland Scotland. Residual features of Scots are often regarded as slang.
The varieties of Modern Scots are generally divided into five dialect groups:
The southern extent of Scots may be identified by the range of a number of pronunciation features which set Scots apart from neighbouring English dialects. Like many languages across borders there is a dialect continuum between Scots and the Northumbrian dialect, both descending from early northern Middle English. The Scots pronunciation of come [kʌm] contrasts with [kʊm] in Northern English. The Scots realisation [kʌm] reaches as far south as the mouth of the north Esk in north Cumbria, crossing Cumbria and skirting the foot of the Cheviots before reaching the east coast at Bamburgh some 12 miles north of Alnwick. The Scots [x]–English [∅]/[f] cognate group (micht-might, eneuch-enough, etc.) can be found in a small portion of north Cumbria with the southern limit stretching from Bewcastle to Longtown and Gretna. The Scots pronunciation of wh as [ʍ] becomes English [w] south of Carlisle but remains in Northumberland, but Northumberland realises “r” as [ʁ], often called the burr, which is not a Scots realisation. The greater part of the valley of the Esk and the whole of Liddesdale have been considered to be northern English dialects by some, Scots by others. From the nineteenth century onwards influence from the South through education and increased mobility have caused Scots features to retreat northwards so that for all practical purposes the political and linguistic boundaries may be considered to coincide.
