Wer kann denn schon ja sagen?

Abstract The article explores German discourse particles (DiPs) in rhetorical wh-questions (wh-RQs). While schon (roughly ‘unexpectedly’) only marks rhetorical wh-questions, denn (roughly ‘I wonder’) marks contextually arising information-seeking or rhetorical Questions under Discussion (QuDs), with or without schon. Since ja (roughly ‘unquestionably’) marks shared information, it is incompatible with questions by itself, but occasionally occurs in wh-RQs left of DiPs like schon instead of denn. The results of two acceptability judgment experiments confirm that ja is strongly dispreferred in RQs, the presence of schon improves RQs with and without ja, and denn has no effect on acceptability. A follow-up study further indicated the rhetorical reading of our target questions to prevail independently from DiPs. We conclude that ja in RQs operates on the information contributed by elements like schon, denoting roughly that the issue in question arises ‘unquestionably against expectations’. Our contexts were neutral regarding the discourse functions of ja and denn (side remarks vs. QuDs), unlike the contexts of the findings, from which we deduce that the marked ja schon-RQs, while grammatical, require specific felicity conditions. A first attempt to confirm this experimentally was globally unsuccessful and could only reveal potential hints in an exploratory analysis.
