Abstract
Abstract In this paper, I propose an analysis for tonal alternations at the prefix–stem boundary in Tenyidie (Angami), where Mid tones in prefixes and stems dissimilate. I argue that this alternation is driven by the OCP (Obligatory Contour Principle) (Leben 1970) of Mid tones. However, sequences of Mid tones are seen elsewhere. I claim that this asymmetry can be solved with recourse to prosodic phonology (Nespor & Vogel 1986/2007). By assuming that stem and suffix form a prosodic word, excluding prefix, I argue that Mid tones fuse within the prosodic constituent to avoid OCP-Mid. The same constraint also triggers dissimilation across the prefix–stem environment, because of prohibition of fusion across prosodic boundaries. This is an example of phonological conspiracy where multiple processes work together to repair or avoid a single marked structure (Kisseberth 2011).
