This study analyses three remarkable features in the person marking system of Sastod Rgyalrong spoken in Khrochu (Heishui) County of Aba Prefecture in northern Sichuan: double person marking, S/A subject agreement (as opposed to the Pan-Rgyalrongic scenario-driven split agreement), and dative-marked arguments as agreement controllers. Comparison with other Rgyalrong languages and exploration of semantic factors underlying the distribution of predicate types that require subject agreement and dative marking reveal the possible evolution and typological significance of the phenomena under study. Double person marking in Sastod Rgyalrong appears to continue an archaic morphological trait. On the other hand, subject agreement and core dative marking appear to be innovative developments induced by intense contact with Qiang, embodying a typological shift towards a dependent-marking grammatical profile. Our findings not only lend strong support to Tsunoda's insights regarding the repercussions of object- affectedness on syntactic structure, but also contribute significantly to them by demonstrating that, in addition to transitive case frames and syntactic constructions like the passive and antipassive, selection between agreement patterns is another valid cross-linguistic correlate of the affectedness scale of transitive predicates. |
