Discourse, sentence grammar and the left periphery of the clause

The term left periphery refers to that area on the left of the subject, in the syntactic representation of a clause, where the relationships with the context are encoded. In this work I propose a syntactic analysis that goes beyond mere sentence grammar and integrates prosodic and discourse features as well. On the one hand, this move accounts for some observations previously not fully understood, such as the anomalous syntactic properties of Clitic Left Dislocation and Hanging Topic, their differences with respect to Focus and their similarities with parentheticals. On the other, it aims at providing a theory of grammar able to encode the relationships between sentence grammar, context and bigger units such as discourses.
