The polarity of a sentence is crucial for its meaning. It is thus hardly surprising that languages have developed devices to highlight this meaning component and to contrast statements with negative and positive polarity in discourse. Research on this issue has started from languages like German and Dutch, where prosody and assertive particles are systematically associated with polarity contrast. Recently, the grammatical realization of polarity contrast has been at the center of investigations in a range of other languages as well. Core questions concern the formal repertoire and the exact meaning contribution of the relevant devices, the kind of contrast they evoke, and their relation to information structure and sentence mood. This volume brings together researchers from a theoretical, an empirical, and a typological orientation and enhances our understanding of polarity with the help of in-depth analyses and cross-linguistic comparisons dealing with the syntactic, semantic, pragmatic and/or prosodic aspects of the phenomenon.

This book provides linguists with a clear, critical, and comprehensive overview of theoretical and experimental work on information structure. Leading researchers survey the main theories of information structure in syntax, phonology, and semantics as well as perspectives from psycholinguistics and other relevant fields. Following the editors' introduction the book is divided into four parts. The first, on theories of and theoretical perspectives on information structure, includes chapters on topic, prosody, and implicature. Part 2 covers a range of current issues in the field, including focus, quantification, and sign languages, while Part 3 is concerned with experimental approaches to information structure, including processes involved in its acquisition and comprehension. The final part contains a series of linguistic case studies drawn from a wide variety of the world's language families. This volume will be the standard guide to current work in information structure and a major point of departure for future research.

Interrogative Phrases and the Syntax-Semantics Interface starts by analyzing the interpretation of interrogative phrases in single and multiple constituent questions, including their interpretation under adverbs of quantification. The results are then put to work in a novel approach to some of the constraints on dependencies between fronted interrogative phrases and the associated gaps: superiority, weak crossover, as well as the so-called `weak islands' (the WH-island, the negative island and the Factive Island). It is argued that the possibility of fronting an interrogative phrase out of these configurations is determined by a semantic/pragmatic condition on questions, which requires them to be answerable. The analysis is worked out principally on Romanian, a language which allows multiple wh-fronting. The results are then extended to English. Audience: Researchers and students in syntax, semantics and their interface, as well as linguists studying the relation between the acceptability of sentences and the larger discourse context.
