Ever since it became a kingdom, Scotland has had two native languages, Gaelic (which in the fifteenth century was called Ersche) and Scots, both of which you will find used in the Gil Cunningham books. I have translated the Gaelic where needful, and those who have trouble with the Scots could consult the online Dictionary of the Scots Language, to be found at http://www.dsl.ac.uk/dsl/
