Uses
In most languages, tag questions are more common in colloquial spoken usage than in formal written usage. They can be an indicator of politeness, emphasis or irony. They may suggest confidence or lack of confidence; they may be confrontational, defensive or tentative. Although they have the grammatical form of a question, they may differ from questions in that they do not expect an answer. In other cases, when they do expect a response, they may differ from straightforward questions in that they cue the listener as to what response is desired.
