This study investigates reflexives in Kaqchikel (Mayan; ergative, V1) and argues that they should be analyzed in terms of the functional head approach (Labelle 2008). The paper proposes that in Kaqhikel there is a special Voice-type head that introduces an external argument and establishes co-reference between the object and the subject. Labelle's original analysis is further elaborated to account for the specific Kaqchikel data and one puzzle in particular: the peculiar behavior of relational nominal predicates (similar to English friend, enemy) in contrast with non-relational nominal predicates. Finally, the paper draws a parallel between transitive verbs and relational nouns and advocates the idea that the reflexive voice head can select nominal complements as well as VPs.
