We present experimental evidence bearing on Cheng and Rooryck's (2000) proposal that French wh-in-situ questions are licensed by an intonational morpheme also present in yes-no questions and their claim that such questions are ungrammatical without a rising contour. While most participants produced a rising contour, not all did; when they did, the slope was not as steep as in yes-no questions. Our findings support C&R's proposal, admitting the central role of information structure. We support a view of question formation in French in which information structure, syntax, and prosody form a tight relationship: the shape of the syntactically-designated contour is affected by pragmatic information. We present a theoretical account appealing to movement through givenness-marking that explains the observed pitch compression.
