V2 violations in different variants of Icelandic: A common denominator?

Abstract

In this article, we report on a number of violations of (or exceptions to) the so-called V2 constraint in different variants of Icelandic. The main purpose is to investigate what these violations can tell us about the nature of the V2 constraint, its vulnerability, the limits of syntax, and about children’s ability to sort out what is relevant and what is not in the input they hear during the acquisition period. Three main explanatory possibilites are taken under consideration: the use and acceptance of sentences with V2 violations in Icelandic (i) is due to English influence, (ii) indicates an expansion of patterns existing in the language for language-internal reasons, (iii) is due to a task effect. In brief, our results support (i) for heritage Icelandic but not for non-heritage Icelandic, while different subsets of our data are best accounted for in terms of either (ii) or (iii).
