Multiple sources for the German scandal construction

The interaction of several cases of grammaticalization going back to different source constructions may have dramatic consequences on a linguistic system. This paper discusses the so-called German scandal construction, which consists of a verbal complex displaying a number of synchronic form-meaning mismatches. The scandal is solved if a diachronic point of view is adopted, which shows that the mismatches result from the intraference of two different source constructions expanded in the course of the German linguistic history, namely the Perfekt construction and the zu-infinitive construction.
