Dominance is non-representational: evidence from A'ingae verbal stress

A'ingae (or Cofán) is a language isolate spoken in the Ecuadorian and Colombian Amazon. This study presents a description and analysis of the language's morphologically conditioned verbal stress assignment. Specifically, I show that A'ingae verbal morphemes can be classified with two binary parameters: the presence or absence of prestressing and the presence or absence of stress deletion (i.e. dominance), which vary independently. I formalise my analysis in Cophonology Theory, a non-representational theory of the phonology–morphology interface, which captures morpheme-specific phonology with constraint rankings particularised to morphological constructions. I argue that while non-representational approaches such as Cophonology Theory can handle the facts of A'ingae stress deletion straightforwardly, representational approaches lack the expressive power necessary to capture the stress facts of the language.
