Scots

From Teflpedia

Scots or Lowland Scots is, according to perspective, either a dialect of English or a language in its own right - the distinction between language and dialect being rather fuzzy.[1] This also has a dimension of language politics.

Scots is largely mutually intelligible with standard English. Speakers of Scottish English often have little difficult with it; speakers from England, Wales and Ireland can usually understand most of it, particularly if they are culturally familiar with Scottish slang.
