ABSTRACT
Scottish Gaelic belongs with Irish and Manx to the Goidelic division of the Celtic branch of Indo-European: i.e. to Q-Celtic. Goidelic Celtic seems to have been brought to Scotland by the Scoti, an Irish tribe who settled in central Scotland around the middle of the first millennium ad. Here, they formed an enclave between Brythonic Celtic speakers to the south and the Picts to the north. Little is known about the Pictish language; it may well have been non-Indo-European.
