I am grateful to Sigurd Nordlie and Gunnar Nyström for having shared their knowledge of and intuitions about the North Gudbrandsdal and Älvdalen varieties with me. I also thank Gunnar Nyström, Tomas Riad, Norval Smith, and Allison Wetterlin for valuable comments on an earlier draft of this article. Thanks are also due to two anonymous referees for several suggestions that have no doubt improved the article, and to the audiences at different conferences and workshops where I have presented this research. Most of all, however, I would like to thank the speakers of the North Gudbrandsdal and Älvdalen communities who made this research possible by generously sharing their time and mother tongues with me.
