There is such a thing as a separate Scots [?] language, a form of Gaelic.
Perhaps it stems from there ...

There is a case for recognising Scots (aka Lallans) as a language
separate from English, but this is a language belonging to the Anglo-
Frisian branch of Germanic. The Goidelic language of Scotland is called
Gaelic, or Scots Gaelic if you wish to distinguish it from Irish and
Manx Gaelic.
