Passive, Causative, and Light Verbs: a Study on Theta Role Assignment

In the enterprise of generative grammar, it has been considered desirable to minimize assumptions and eliminate redundancy. Following this tradition, Chomsky (1992) proposed that the internal interface levels, D-structure and S-structure, should be eliminated from the grammatical model, because there is no conceptual necessity for those levels. In this thesis, I show that to analyze Japanese passives, Romance causatives, and light verb constructions, we must abandon D-structure as a pure representation of GF-q relations. Thereby, I propose analyses which are compatible with Chomsky's new grammatical model without D-structure, and provide support for Larson's (1988) theory of q-role assignment, in which qroles are assigned in the course of the derivation. Furthermore, I explore theoretical and empirical consequences derived from those proposals. In chapter 2,1 point out that the ni direct passive verb in Japanese has dual characteristics, the combined function of the passive morpheme -en and the verb get of the get passive. To explain these properties, I propose that this passive verb triggers Passivization at the initial point of the derivation, but assigns q-roles at a later point of the derivation (Hoshi 1994b, cf.
