Focus and Givenness: a Unified Approach Michael Wagner Mcgill University
1 Focus and Givenness: A Unified Approach Michael Wagner McGill University Abstract Theories about information structure differ in treating focus-, contrast-, and givenness-marking as either a single phenomenon or as distinct phenomena. This paper argues for a unified approach, following the lead of Schwarzschild (1999), but a unified approach based on local alternatives (Wagner, 2005, 2006b).1 The basic insights of the local alternatives approach are captured using a new formalization, which aims to fix several problems in the original proposal noted in B¨uring (2008). The unified approach is compared with alternative approaches that invoke separate mechanisms for givenness and focus: the disanaphora approach (Williams, 1997), the F-Projection account (Selkirk, 1984, 1995), and the reference set approach in Szendr¨oi (2001) and Reinhart (2006). All of these have fundamental problems, and the requisite revisions render them equivalent to the local alternatives approach. Keywords: alternatives, focus, givenness, prosody, contrast, information struc- ture 1 The label ‘local alternatives’ for the ‘relative giveneness’ account in Wagner (2005, 2006b) was proposed in Rooth (2007) and seems like a more appropriate term. 2 Michael Wagner 1.1 Three Phenomena, or Two, or One? The distribution of accents in a sentence in English is affected by informa- tion structure in a systematic way. Information structure comprises a broad set of phenomena. This paper looks at three types of effects that influence the prosody of a sentence, those of question-answer congruence, contrast, and givenness, and presents evidence—some new, some already presented in Wag- ner (2005, 2006b)—that all three should be treated as reflexes of the same underlying phenomenon.
