Dissertation Abstract:
This dissertation takes a biolinguistic perspective on Labovian variation in morphosyntax, an important phenomenon discovered by sociolinguists (Chambers, Trudgill and Schilling-Estes 2002). The dissertation asks how an account of the mechanisms underlying such variation can be incorporated into a Minimalist theoretical model of the human language faculty (Chomsky 1995, et seq.). To address this question, three cases of morphosyntactic variation in English are investigated using an adapted combination of variationist and theoretical methods. A primary empirical focus is on the moribund English variety spoken in the community of Smith Island, Maryland, where both phonological and morphosyntactic variants are currently undergoing a process of rapid change as the insular dialect approaches death due to ongoing population attrition (Schilling-Estes and Wolfram 1999). This dissertation considers two morphosyntactic variants on Smith Island: weak expletive 'it' (Parrott 2002) and leveled 'weren't' (Schilling-Estes 2000, Mittelstaedt 2006). The dissertation also examines the puzzle of pronominal case-form mismatches and pronoun-specific ordering asymmetries that occur in English coordinate noun phrases (Emonds 1986). This dissertation adopts a particular Minimalist theory of syntax (Chomsky 2000) augmented with the independently motivated and well-articulated theory of Distributed Morphology (DM, Halle and Marantz 1993, Embick and Noyer to appear). In this theoretical model, mechanisms of Labovian variation can be located in the features of syntactic terminals and their combination in the narrow syntax, as proposed by Adger and Smith (Adger and Smith 2005, Adger 2006). Evidence from the three case studies supports the additional hypothesis that mechanisms of variation are located in the morphological component of the language faculty, at the interface between the syntactic computation and the phonological component. Specifically, it is claimed that variation can arise from the inventory and feature structure of non-competing Vocabulary Items and their interactions with ordered operations during the morphological computation to the Phonetic-Form interface. By showing how actual cases of morphosyntactic variation might receive a plausible analysis within the Minimalist-theoretical framework of DM, an overarching goal of the dissertation is to advocate further cooperative research efforts toward bridging the gap between biolinguistic theory and the empirical study of Labovian variation and change in progress.
