On the Syntax of Instrumental Clauses: The Case of Indem-Clauses in German

In this article, I examine the external and internal syntax of instrumental indem-clauses in German. As a subordidating conjunction, indem takes a finite TP as its complement and triggers verb final position. I provide evidence showing that instrumental indem-clauses can only operate on the content level and that they cannot be interpreted epistemically, nor can they modify a speech act. Furthermore, I argue that although indem-clauses are restricted to a particular interpretation, they can attach at two distinct heights in the matrix clause. If they are analyzed as central adverbial clauses, they attach as T[ense]P[hrase] adjuncts. If, on the other hand, instrumental indem-clauses are treated as peripheral adverbial clauses, they are taken to be J[udge]P[hrase] adjuncts. Main evidence for the analysis comes from: i) variable binding and Principle C effects, ii) movement to the left periphery of the matrix clause, and iii) licensing conditions of weak and strong root phenomena.
