comment question

comment question (kommentarspørsmål): a communicative function which is typical of dialogue. Comment questions are formally similar to tag questions, but slightly different in function, as they are largely signals from a hearer that s/he acknowledges the speaker's statement, and invites him/her to continue. E.g. A: I've just been to the bookshop. B: Oh, have you? Comment questions are usually spoken with falling intonation.
