Double causatives, lability and elusive agent in Mehweb

Abstract

Abstract In this paper, I consider double causatives in Mehweb, a one village language spoken in Daghestan, Russia, and belonging to the Dargwa branch of East Caucasian. The capability of stacking two causative suffixes seems to be lexically restricted, and mapping onto verbal meanings that are typically P-labile in the languages of the family. Interestingly, the verbs allowing double causatives are not morphosyntactically labile in Mehweb, which is generally poor in labile verbs as compared to sister languages. I conclude that the ability to form double causatives is not a consequence of the morphosyntactic property of being labile; rather, both morphosyntactic properties follow from the same component of the lexical semantics of these verbs and ultimately from the properties of the situational concepts they convey. As a tentative functional explanation I suggest that the relevant property is the weakened status of the agentive participant.
