Causative constructions in Persian and Azari

This study aims at investigating the causative construction in Persian and Azari. There is both syntactic and morphological causativisation in these languages. In Azari, double causativity is possible just by using a morphological strategy, but in Persian both syntactic and morphological strategies are used to form double causative constructions. In Persian, causativisation and passivisation interact with each other in a sentence both syntactically and morphologically, while in Azari they cannot co-occur when a morphological strategy is used for both. It seems that the behaviour of instrumental and benefactive cases is different from other cases in causative constructions. The rich case systems of both languages as used in the causative construction are examined and the findings support the accessibility hierarchy, proposed by Comrie (1989)
