Inferential Interrogatives with qué in Spanish

In this paper, we discuss the evidential properties of inferential interrogative sentences with que in Spanish. This interrogative type exhibits the shape of a wh-question but the interpretation of a polar question. These sentences have the additional particularity that they are interrogatives with evidential material, which are attested but not frequent crosslinguistically, if compared with declarative evidentials. An interesting consequence of their double interrogative and evidential nature is the fact that both discourse participants have a prominent role in the interpretation of these sentences, as the Speaker makes the inference but the Addressee is requested for confirmation. To account for the construction, we assume a multiple-layered system that includes both Speech Act projection and Finiteness projection. In these two areas we simultaneously find evidential material housing the Speaker's inference, and a raised Addressee in its prominent interrogative position as the participant with the knowledge to provide the requested confirmation of the interrogative's truth value.
