Iterative Footing and Prominence-driven Stress in Nanti (kampa)

In this article we describe and develop an optimality-theoretic (OT) analysis of foot-level (secondary) and word-level (primary) stress in Nanti, a Kampa language of Peru. The distribution of stress in Nanti is sensitive to rhythmic factors, syllable quantity, vowel quality, and to whether a syllable is open or closed. The interaction of these independent variables produces a complex, multigrade stress scale married to an iterative stress system whose default preference is alternating, iambic rhythm. While each of the interacting factors in this system is familiar to phonologists, Nanti is special because the particular combination of influences and factors in Nanti contributes to a complexity of interactions that has not been documented in any other language to date.*
