On the integration of dative adjuncts into event structures in Yapa languages

Warlpiri and Warlmanpa (Ngumpin-Yapa languages of Australia) exhibit a complex predicate construction in which a class of preverbs introduces a single argument that is not shared by the argument structure of the inflecting verb, nor is there necessarily any shared event structure. This is problematic for many theories of linking structures of complex predicates, since no arguments or events are shared between the predicative elements of the complex predicate. The same grammatical relation is instantiated by a beneficiary adjunct. In light of new research in event and argument structure, I propose a lexical rule which introduces an applicative argument to account for the beneficiary construction; and that the preverbs take another predicate as one of their arguments to account for the complex predicates. The applicative rule and the preverbs both introduce an argument of the same grammatical relation, leading to interesting interactions, given that two grammatical relations of the same type are not expected to co-occur within a single clause.
