Grammatical relations in Yaqui

This paper describes a number of selectors for grammatical relations in Yaqui. The main selectors discussed in the paper include case marking, word order, suppletion, passive and valency-increasing mechanisms, control and anaphoric constructions. The study reveals two crucial aspects: Yaqui is a good example of a language where grammatical relations can be characterized as a construction-specific category, and the distinction between core and non-core arguments is essential to determine the selected argument in particular constructions.
