The prefield after the Old High German period

The filling of the prefield in Modern German is determined by information-structural constraints such as scene-setting, contrastiveness, and topichood. While OHG does not yet show competition between these constraints, competition arises from MHG onward. This has to do with the generalization of the V2 constraint (i.e. the one-constituent property of the prefield) for declarative clauses, in which context the information-structural constraints are loosened. The syntactic change whose result eventually was the loss of multiple XP fronting comprised a change of the feature endowment of C because the fronting of expletive thô (roughly in the OHG of the ninth century) led to the reanalysis of XP fronting as a semantically vacuous movement whose only function is to check the EPP feature of C. Data from doubly filled prefields in ENHG and post-initial connectives indicate that an articulated split CP-structure, as proposed within the cartographic approach, is also at play in German.
