Impersonal Construction in Gilaki of Langroud

In this research, we examine the Impersonal Constructions in Guilaki within the framework of Minimalist theory. The purpose of this research is to determine the nature of preverbal element. We will show how the case of DP at the clause-initial position of these constructions, is checked. Also we will discuss the merge position of this DP and where it moves in overt syntax. Examining Guilaki data reveals that the impersonal construction involves a compound verb and the verb is unaccusative. The preverbal element as the head of the predicate assigns experiencer theta role to the DP at the initial position of the constructions under study. This DP is in fact the complement of rā which is a postposition, so they form a prepositional phrase (PP). This PP is merged in the specifier position of the predicate phrase (or Spec of VP). We apply subjecthood tests to the DP and it does not pass any of these tests. So it does not move into the specifier position of tense phrase. Hence, we conclude that the PP has been topicalized and Guilaki lacks quirky subject.
