Clause type vs speech act: Knowledge confirmation questions in Basque

This article analyzes Knowledge Confirmation Questions (KCQ) in Basque, an instance of non-canonical questions that has not been analyzed yet. KCQs display three characteristic elements, namely, (i) a declarative-type syntax, (ii) an interrogative-like intonation, and (iii) the discourse particle ba; and are interpreted as follows: “Do you know that p?”. Here, I propose that the meaning contribution of KCQs derives from the interaction of these three elements. More precisely, I argue that their question-like intonation, which adds interrogative interpretation, takes scope over ba, which regulates the addressee’s Doxastic State and undergoes context shift. Basque KCQs constitute an interesting case study, because they raise some interesting questions on the syntactization of discourse and the properties of discourse particles, as they seem to contradict the assumption that discourse particles do not fall under the scope of sentential operators.
