Heritage Languages and Syntactic Theory

This volume explores a wide range of structural phenomena in typologically diverse heritage languages using current Minimalist theoretical approaches. Heritage languages have been the focus of extensive research in the last three decades; by virtue of their inherent diversity stemming from initial learning conditions, they pose significant challenges to traditional methods of linguistic description that rely on uniform conceptions of what 'knowledge of language' should be. Despite the existence of inter- and intra-speaker variation in the grammars of heritage languages, there are also significant shared development trends and structural outcomes that cannot be considered to be purely circumstantial. The studies presented in this volume illustrate the practicality and usefulness of subjecting domains of heritage language syntax to rigorous formal analysis.
The chapters also have implications for theory-building efforts within the current Minimalist landscape; they force a reassessment of our understanding of the ideal speaker-hearer (Chomsky, 1965) in the context of bi- and multi-competent individuals and communities. In line with recent trends in contemporary Minimalism that largely eschew the notion of traditional parameters and an enriched view of Universal Grammar, the integration of heritage languages into syntactic theory adds an important piece of the puzzle relating to linguistic competence. The volume also in some respects calls for a re-evaluation of the prevailing stance that the syntax of heritage languages is predominantly immune to significant decay or change.
