The description of the interdependence of tonal and stress features in Papiamentu provides important insights on the genesis of mixed creole systems in which these suprasegmental features are phonologically distinctive. The present account represents a constraint-based and feature-based analysis that, unlike proposals in which the relations between tone and stress constitute simply a set of association conventions, proposes that tone and stress are directly related. This paper includes (a) a description of four basic lexical patterns of tone and stress in Papiamentu, (b) a discussion of problems that alternative analyses face when dealing with mixed systems, and (c) a principled way to explain relations between suprasegmental features.
