Prolific domains and the left periphery

Abstract

The left periphery has enjoyed extensive study over the past years, especially drawn against the framework of Rizzi (1997). It is argued that in this part of the clause, relations are licensed that have direct impact on discourse interpretation and information structure, such as topic, focus, clause type, and the like. I take this line of research up and argue in favour of a split CP on the basis of strictly left-peripheral phenomena across languages. But I also want to link the relation of articulated clause structure, syntactic derivations, and information structure. In particular, I outline the basics of a model of syntactic derivation that makes explicit reference to the interpretive interfaces in a cyclic, dynamic manner. I suggest a return to older stages of generative grammar, at least in spirit, by proposing that clausal derivation stretches over three important areas which I call prolific domains: the part of the clause which licenses argument/thematic relations (V- or θ-domain), the part that licenses agreement/grammatica1 relations (T- or ϕ-domain), and the part that licenses discourse/information-relevant relations (C- or ω-domain). It is thus a rather broad and conceptual notion of "adding" and "omitting" that I am concerned with here, namely licensing of material to relate to information structure, and the desire to find an answer to the question which elements might be added or omitted across languages to establish such links
