Summary

Jakob Jakobsen An Etymological Dictionary of the Norn Language in Shetland…

Of the Norn words that are not in general use throughout Shetland, some belong to certain larger portions of the Islands, as, for example, North Shetland, more strictly, the North Isles; the Westside; South Shetland; but many are limited to a single district or to a single island.
Of the great mass of words that have become antiquated, some cannot be said to have perished, as they are still used by old people, though often only in certain islands, districts or neighbourhoods; they are not to be heard in the speech of younger people.

Jakob Jakobsen An Etymological Dictionary of the Norn Language in Shetland…

The old Norse speech of Shetland shows in its vocabulary a close connection with the mother-tongue, Norwegian, a closer connection than that shown by Icelandic and partly by Færoese with the same language, the common mother-tongue of them all. This circumstance has a natural explanation in the fact that Shetland was situated so much nearer to Norway. Certainly the political connection between the Islands and Norway was severed by the mortgaging of the Islands to Scotland in the 15th century
