Scots language refers to the Anglic varieties derived from early northern Middle English spoken in parts of Scotland. In Scotland it is sometimes called Lowland Scots or its contraction Lallans to distinguish it from Scottish Gaelic spoken by some in the Highlands and Islands (especially the Hebrides) and small communities in the urban lowlands. Scots is also spoken in parts of Northern Ireland and border areas of the Republic of Ireland, where it is known in official circles as Ulster Scots or Ullans.
Since there are no universally accepted criteria for distinguishing languages from dialects, scholars and other interested parties often disagree about the linguistic, historical and social status of Scots. Although a number of paradigms for distinguishing between languages and dialects do exist, these often render contradictory results (See Dialect). Consequently, Scots has, on the one hand, been traditionally regarded as one of the ancient dialects of English, but with its own ancient and distinct dialects. Scots has often been treated as part of English as spoken in Scotland but differs significantly from the Standard Scottish English taught in schools. On the other hand, it has been regarded as a distinct Germanic language the way Swedish is distinct from Danish.
Its subordination to Anglo-English has also been compared to the subordination of West Frisian to Dutch in the Netherlands. However, use of the word subordination in this context also implies that a standard or proper version of the language, in this case English, actually exists. Thus Scots can be interpreted as a collective term for the dialects of English spoken or originating in Scotland, or it can be interpreted as the autochthonous language of Lowland Scotland.
