Person agreement with inherent case DPs in Chirag Dargwa

Abstract

The article argues that the syntactic behavior of non-absolutive subjects of finite clauses in the Nakh-Daghestanian language Chirag Dargwa is a result of their interaction with two different functional heads in a clause: v and T. Discussing empirical data from Chirag, I present the puzzling behavior of person agreement, which shows selective sensitivity to arguments in the ergative, dative, and genitive cases. The primary evidence comes from the periphrastic causative, which displays some typologically unusual properties in case marking and agreement. I show that the ability to trigger person agreement is not an intrinsic property of ergative, dative, and genitive DPs in Chirag, but rather is endowed to the highest DP in T’s c-command domain over the course of the derivation. I propose that all non-absolutive subjects start out as DPs assigned inherent case and a theta-role by v, and that T further assigns structural nominative case to the DP in Spec,vP, thus making it accessible to φ-probes.
