This paper analyzes the ergative-antipassive alternation in Inuktitut using a variationist sociolinguistic approach. This alternation is not a typical linguistic variable, as these constructions are traditionally believed to have different syntactic functions. However, the nature of those functions remains controversial (e.g., Bittner 1987, Manga 1996), and they are undergoing changes in some dialects (e.g., Johns 2001, Carrier 2012), with the antipassive being increasingly used in place of the ergative. Thus, a variationist sociolinguistic approach is employed here to identify the significant functions of these constructions, and to find the specific context where they overlap and the language change is taking place. The study examines data collected in Resolute Bay, Nunavut, which presents a case of new-dialect formation due to the High Arctic relocation. The analysis reveals the functions of these constructions, describes the source of fading ergativity for the dialects considered in this study, and supports Trudgill's (2004) theory on new-dialect formation.

It is often supposed that dialect contact and dialect mixture were involved in the development of new colonial varieties of European languages, such as Brazilian Portuguese, Canadian French, and Australian English. However, while no one has denied that dialect contact took place, the role of dialect mixture has been disputed. Among those who do not accept a role for it, some have also considered the role of identity, especially new national identities, to be self-evident. This article argues for the role of dialect mixture and against the role of identity. It presents case studies from pre-16th-century colonial expansions of European languages, an era when any role for national identities would be very hard to argue for. Instead, it suggests that dialect mixture is the inevitable result of dialect contact, and that the mechanism which accounts for this is quasi-automatic accommodation in face-to-face interaction.NOTE: Very many thanks for help with this article go to David Britain, Brian Joseph, Lesley Milroy, James Milroy, and especially Max Wheeler.
