Ergativity in Indo-Aryan

Abstract

Case and agreement patterns that are present in Old, Middle, and New Indo-Aryan languages have been argued to require the following perspective: since ergative case marking and ergative (object) agreement in these languages are historically tied to having originated from the past perfective morphological marker ta, they can only be fully understood from a perspective that factors in this development. Particular attention is given to the waxing and waning of ergative properties in Late Middle Indo-Aryan and New Indo-Aryan, which give rise to recurring dissociation of case and agreement; specifically, object agreement in the absence of ergative case marking is attested in Kutchi Gujarati and Marwari, whereas ergative case marking without object agreement is present in Nepali. With regard to case, recent insights show that “ergative/accusative” may be regularly semantically/pragmatically conditioned in Indo-Aryan (so-called differential case marking). Pertaining to agreement, a central theoretical question is whether “ergative” object agreement should be analyzed uniformly with subject agreement or, alternatively, as a type of participle agreement—drawing on synchronic parallels between Indo-Aryan and Romance.
