It is a much-debated issue whether one should assume separate lexical entries for participles used in passive and perfect constructions or whether there is just one lexical entry that is used in different ways depending on whether a passive or perfect auxiliary is present in the clause. In previous work I criticized approaches trying to analyze the passive with one lexical entry for making empirically wrong predictions and suggested a lexical-rule based approach were two different lexical items for the participle are licensed. In this paper I show how Heinz and Matiasek's (1994) formalizations of Haider's (1986) ideas can be extended and modified in a way that both modal infinitives and control constructions can be captured correctly. The suggested analysis needs only one lexical item for participles, base form infinitives, and zu infinitives irrespective of their usage in active or passive like structures.
