We present evidence from acceptability judgment experiments that there is systematic prosodic givenness marking in Czech in that discourse-salient elements avoid sentence stress, contra the claim in Kučerová 2007Kučerová , 2012 that givenness is marked only syntactically -by establishing a word order in which all given elements precede all new ones -and not prosodically in Czech. We argue that the syntactic movement of given elements results from the need to avoid the rightmost position where sentence stress falls, and not from a syntactic ordering requirement. This is supported by the empirical finding that given objects need not scramble if they are not in sentence-final position, even if they are preceded by new elements (experiment 2). We also argue against Kučerová's claim that given elements are marked only if definite/presupposed in Czech by showing that irrespective of this property, all given objects tend to avoid the sentence-final position (experiment 1). Finally, our results reveal an interaction between presupposition and word order, in the sense of an acceptability penalty for utterances in which non- * We are grateful to the following people for their valuable comments: Philippa Cook, Gisbert Fanselow, Jana Häussler, Beste Kamali, Ayesha Kidwai, Ivona Kučerová, Frank Kügler, Agata Renans, Michael Rochemont, Filip Smolík, Kriszta Szendrői, Barbara Tomaszewicz, Luis Vicente, Malte Zimmermann. Parts of this paper were presented in preliminary versions on two occasions: in a seminar on the relation between information structure and syntax in Potsdam (January 2012) and at the Formal Approaches to Slavic Linguistics 22 at McMaster University (May 2013). We thank the audiences for their comments. The paper has undergone significant revision during the review process. We are grateful to the anonymous reviewers and the editors of Semantics & Pragmatics, esp. Paul Elbourne, for their incredibly valuable comments and questions.
