In this chapter, we will explore the nature of Basque impersonals in comparison with inchoatives, passives, and middles. Our analysis reveals that Basque impersonals share key characteristics with subject-suppressing impersonals (Blevins 2003): (i) they are built on transitive, unergative, and unaccusative verbs; (ii) they feature a human (suppressed) subject; and (iii) their implicit subject cannot be expressed by an oblique. However, Basque impersonals exhibit a detransitivized morphology, contrasting with the transitive shape of this construction in other languages such as Polish. In any case, we demonstrate that Basque impersonals involve a syntactically active external argument, as the implicit subject can bind certain reflexive and reciprocal anaphors, act as a possessor in inalienable possession relations, and license secondary predication. Therefore, Basque impersonals should not be considered passive or middle constructions and must be regarded as subject-suppressed impersonals.
