This paper makes three specific claims about German information structure and the interface between information structure and syntax. First, the phenomenon known as 'Subpart of Focus Fronting' in German is constrained by discourse context, namely subordinating discourse relations. Second, information structure should be present in the syntax, minimally via a discourse subordination feature on C. Third, methodologically, the Question-Answer paradigm alone is not sufficient to diagnose the complete information structure of the answer; topicalization may occur out of a putative focussed phrase.
