A yes-no interrogative (clause) is an interrogative to which yes or no is the only possible answer. Any other reaction on the part of the hearer (‘Of course’, 'I don’t think so’) are responses, but not answers. This clause type can also be referred to as a total interrogative (the scope of the interrogation is the entire clause rather than just one part of it) or a closed interrogative (the number of answers is limited to two): Do you live here? Is everything all right? Was there a problem? (AEG Ch. 2)
