The study of questions and answers is challenging for various fields of theoretical linguistics, logic, analytical philosophy, and more recently computer science. Research into questions and answers addresses old and raises new and important questions about the semantics / pragmatics interface and about the dynamics of interpretation. This book brings together current work on the topic as it has been developed in Amsterdam, and congenial academic sites, over the past 15 years. Amsterdam is one of the breeding grounds for the formal study of logic and language, for dynamic semantics, and for the study of questions and answers. It covers the major issues of pragmatic/semantic investigation, including logical relations, context dependence, information structure, and more. It illustrates how semantic/pragmatic stance can be used for problems in other areas of linguistic theorising.
