This chapter describes grammatical relations in Katla, a Niger-Congo language of Sudan. Katla exhibits a close match between semantic and syntactic valency, and monovalent, bivalent and trivalent verbs can be distinguished by their ability to occur with one, two or three unmarked arguments respectively. Katla shows evidence for the existence of a subject category (including S, A and ADITR, whereby ‘DITR’ as subscript arguments) and of a primary object category (including P and G arguments; but excluding T arguments). Evidence for these categories comes from argument indexing, constituent order and valency-changing morphology. Other potential argument selectors are also discussed, but they provide inconclusive evidence. The chapter concludes with a brief comparison to the closest relative, Tima, showing considerable differences between the two languages.
