The chapter aims to provide the theoretical background that is necessary to understand the research questions addressed by the chapters in this collection. We identify and discuss the key claims grounding Sbisà’s deontic approach to speech actions, while locating her contribution within the broader literature on speech acts and their nature. In particular, we focus on her distinctive Austinian-inspired understanding of the conventionality of illocutionary acts, their core effects, and the role of presupposition accommodation in force assignment. We close with an outline of the collection’s structure and contents.
