Jakob Jakobsen, An Etymological Dictionary of the Norn Language in Shetland…
“ The Danish vocabulary in Shetlandic is, however, relatively large and of weight, and contains not a few strongly-marked old dialect words, so there certainly must be an original or, at all events, very old Danish element in Shetlandic. Some of the words may have been in use, in ancient times, both in Denmark and in southern Norway. Altogether, the occurrence of the Danish element in Shetlandic strengthens the conviction, reached on other grounds, that the central point for the emigration to Shetland is to be sought in the south-west and south of Norway. ”
