Hybrid intransitives in Basque

This paper deals with a group of agentive verbs in Eastern dialects of Basque that show mixed unergative and unaccusative properties. Although they pattern with unergatives in certain aspects, they combine with an absolutive subject and the auxiliary ‘be’, contrary to what one would expect for Basque unergative verbs. Additionally, they behave like unaccusatives in a number of other tests, such as in their inability to take cognate objects and in allowing partitive subjects. The analysis put forward in this paper accounts for the hybrid nature of these verbs. In particular, we claim that their subject is introduced in the specifier of vP, and that it is coindexed with a thematic but non-pronounced argument of Voice. As a consequence, the subject shows both external and internal properties. This paper thus challenges the mutually exclusive external/internal division of the subject in intransitive verbs and argues that intransitive verbs can be classified into more groups than just two, as also argued elsewhere. Additionally, it argues that the different types of intransitive verbs are grammatically encoded and shaped by different versions of Voice and v. Thus, this analysis assumes the typology of Voice proposed by Schäfer (2008) and developed by Alexiadou, Anagnostopoulou and Schäfer (2015), and extends it to the functional head v.
