What Formal Approaches to Syntactic Interfaces Can Tell Us about the Syntax of Preverbal and Prenominal Constituents in Galician

An important line of research within a generative, formal approach to syntax in the early 21st century has centered on exploring phenomena related to the interface between syntax and other linguistic modules in human language. In this paper, we review the notion of interfaces and how they have been viewed within formal theoretical approaches to monolingual and bilignual competence and language acquistion, noting their relevance as they relate to language acquisition and bilingualism in the context of Galicia (Spain). We review a selection of Noun Phrase (NP) structures that implicate a syntactic interface: subject position, clitic directionality, and determiner clitic allomorphy. We provide a review of the relevant literature and the theoretical issues of interest as they relate to our understanding of these syntactic interfaces, reporting on our current theoretical understandings, persistent questions, and our view of the path forward as it relates to linguistic research on the Galician language.
