Questions Under Discussion: Where Information Structure Meets Projective Content

Abstract

We discuss problems familiar from the literature on presupposition and information structure, and illustrate how a synthesis using the Question Under Discussion (QUD) framework yields fresh insight. In this framework, discourse is analyzed in terms of the strategy of inquiry pursued by the interlocutors, and individual utterances are interpreted relative to the question being addressed. This way of thinking offers a new perspective on diverse phenomena, including the projection of presuppositions, association with focus, contrastive topic marking, and variability of projection behavior. We review the principal issues and prior lines of research in each of these areas, and show how the issues may be recast in QUD terms.
