Scottish island names

The modern names of Scottish islands stem from two main influences. There are a large number of names that derive from the Scottish Gaelic language in the Hebrides and Firth of Clyde. In the Northern Isles most place names have a Norse origin. There are also some island place names that originate from three other influences, including a limited number that are essentially English language names, a few that are of Brittonic origin and some of an unknown origin that may represent a pre-Celtic language. These islands have all been occupied by the speakers of at least three and in many cases four or more languages since the Iron Age, and many of the names of these islands have more than one possible meaning as a result.

Scotland has over 790 offshore islands, most of which are to be found in four main groups: Shetland, Orkney, and the Hebrides, sub-divided into the Inner Hebrides and Outer Hebrides. There are also clusters of islands in the Firth of Clyde, Firth of Forth, and Solway Firth, and numerous small islands within the many bodies of fresh water in Scotland including Loch Lomond and Loch Maree.

As humans have lived on the islands of Scotland since at least Mesolithic times, it is clear that pre-modern languages must have been used, and by extension names for the islands, that have been lost to history. Proto-Celtic is the presumed ancestor language of all the known Celtic languages. Proponents of the controversial Vasconic substratum theory suggest that many western European languages contain remnants of an even older language family of Vasconic languages, of which Basque is the only surviving member. This proposal was originally made by the German linguist Theo Vennemann, but has been rejected by other linguists.
