Until recently, little attention has been paid within syntax to components of discourse meaning that go beyond information structure and fall into the domain of non-at-issue meaning operating at the level of illocutionary force. To approach this domain, many of the contributions of this volume deal with the syntax of discourse particles. However, the issue of how to account for discourse particles within a more explicit map of the illocutionary domain is a good starting point for considering further phenomena related to the syntax of speech acts. By focusing on speech-act related particles and/or meaning domains, this volume makes a new contribution to the field, as existing collections either do not offer a comparatively narrow focus on particles or are not limited to syntax-oriented approaches. The primary audience of this volume are researchers and graduate students interested in state-of-the-art approaches to the syntax-discourse interface within the cartographic approach to syntax.
