Dynamic Semantics for Non-Sentential Utterances

This paper re-examines non-sentential utterances (NSUs) ―expressions lacking sentence form but conveying propositional content―through the lens of dynamic semantics, which treats sentence meaning as context updating. The paper first provides an overview of NSUs and the current state of research. Then, it explores the dynamic aspects of NSU interpretation, proposing a dynamic semantics centered on updates to the interpreter’s information state, including an analysis of epistemic NSUs. Finally, the paper briefly discusses the implications of viewing NSUs dynamically, focusing on their impact on meaning, propositions, and the static-dynamic distinction in semantics.
