Explanation of Deleted Internal Argument in Persian Verb Phrase Based on Dynamic Approach of Phase Theory

This paper trys to explain, based on the framework of the dynamic phase theory, how to eliminate the internal object of the verb in Persian. At first, in order to determine whether deleted internal argument in Persian verb phrase is the result of  argument ellipsis (AE) or verb stranding verb phrase ellipsis (VSVPE), we apply some common diagnostic criteria  in the previous studies such as verb movement out of verb phrase, verbal identity, deletion of prepositional phases as intrnal arguements, coordination structure, order of adverbs of state and objects and scrambling. Because of incapability of the mentioned diagnostic criteria in the previous literature, we resort to the dynamic approach of phase theory (Bošković: 2005, 2013, 2014). Based on this approach, we conclude that what is deleted in the verb phrase is either a phase or the complement of a phase. Accordingly, this approach can provide the readers up with a more comprehensive and economical explanation of the mentioned structure in Persian.
