Irrealis-marked interrogatives as rhetorical questions

Abstract I describe and compare two strategies to form rhetorical questions (RQs) in Sm’algyax (Tsimshianic). I show that one kind is isomorphic to ordinary, information-seeking questions, and is compatible with positive and negative answers, while the second is marked with irrealis morphology and only allows negative answers. I provide evidence from answerability and embedding to suggest that both types of RQs in Sm’algyax behave like questions in terms of their syntax/semantics, and propose that the irrealis subordinator present in the second type signals to the addressee that a negative answer is expected. These findings have implications for the presence of irrealis and subjunctive morphology appearing in RQs crosslinguistically.
