Typology and diachrony of converbs in Indo-Aryan

Non-finite forms constitute an important component of the verbal system of Indo-Aryan (IA) languages. On the one hand, some of them, such as e.g., converbs, have already received proper attention in historical linguistics and typological literature, with regard to Old Indo-Aryan (OIA), Middle IndoAryan (MIA) and New Indo-Aryan (NIA) (cf. Tikkanen 1987; Peterson 1998; Subbarao 2012 among others). Other forms, such as participles, have usually been analysed in the wider context of reorganisation of a finite verbal system which led to alignment change (for recent discussion see Dahl and Stronski 2016). On the other hand, adverbial participles or infinitives have so far been under-studied (cf. Sigorski 2005), particularly within early NIA. This period in the history of IA languages witnessed several important morphosyntactic developments and still requires in-depth study, particularly due to the lack of well-edited corpora. The aim of the present paper is to partly fill this gap by highlighting major trends in the development of constructions based on various non-finite forms in early NIA. We focus on main argument marking in converbal chain constructions and its interplay with the animacy hierarchy. We demonstrate a relative stability of differential case marking (DCM), focusing mainly on conditions on differential subject marking (DSM) and differential object marking (DOM). In addition, we compare converbal chain constructions with participial absolute constructions (AC). Finally, in order to give a holistic view of converbal constructions, we verify the type of linking instantiated by them, focusing on three scopal parameters in converbal constructions (Tense, Illocutionary Force and Negation) and using the apparatus of Role and Reference Grammar and Multivariate Analysis
