‘Counterpresuppositional Focus’ constituents explicitly or implicitly reject and correct a (presumed) presupposition on the part of the Addressee. The Speaker not only wishes to add something to the pragmatic information of A, but also to further specify, change, or correct something in A’s pragmatic information. Probably for this reason, Counterpresuppositional Focus constructions seem to have the most outspoken prosodic prominence patterns in many languages.
