Perfect constructions with existential verbs in nDrapa

This paper aims to provide a full analysis of perfect constructions with existential verbs in nDrapa. Semantically, such construction conveys either a resulting state or a persistent situation, in accordance with the aspectual type of the situation. Syntactically, the existential verb in the perfect construction is not thoroughly grammaticalized as an aspect marker, but retains some element of its core meaning such as denoting that an entity exists. Moreover, they show distinct features from the serial verb constructions in terms of the aff ixation. Regarding a possible historical origin of the perfect constructions with existential verbs, I conclude that it is the functional borrowing from the neighboring languages
