LING 371 Lecture Notes - Lecture 23: Projection Principle, Genitive Case, Preposition And Postposition
Document Summary
Have seen transitive/unaccusatives alternation: the chocolate gets theme theta-role from melt in (a) and (b, the cook melted the chocolate, the chocolatek melted tk. The difference here is that this sentence lacks the agent theta-role, whereas sentence (a) does not lack the agent theta-role. Theta-role represented at d-structure (remember the projection principle) This is why it is in parentheses: the cook melted the chocolate, the chocolate was melted (by the cook). There is a similar kind of analysis for both constructions (10b and 11b: the cook melted the chocolate, the chocolate was melted (by the cook). Need to capture: the theme moves to subject position, the agent is optional, the agent appears in an adjunct pp. When the verb in english (e. g. , melt in the active version) gets. A passive v does not license" an object (more on this later) Object moves to subject position to be licensed" the passive morpheme (-ed), somehow it doesn"t want to take.
