This paper describes and analyzes the morphophonological properties of the causative construction in the Thetogovela dialect of Moro, a Kordofanian language spoken in the Nuba Mountains of Sudan. The causative morpheme, -i, triggers vowel height harmony and palatalization of preceding dental stops. Unlike other extension affixes, it also fuses with the final aspect/mood vowel. Finally, while default tone is normally dependent on the size and shape of the root, the causative imposes a high-low pattern: high tone on the root/stem and a low-toned causative affix. We demonstrate how these processes relate to the causative morpheme's position within the derived stem, a constituent composed of the root, a reduplicative prefix, and extension suffixes, including the causative.
