Morphology-phonology interplay in lexical stress assignment: Ichishkiin Sɨnwit

This paper presents a novel analysis of the stress system of Ichishkiin Sɨnwit (Sahaptian). Ichishkiin Sɨnwit has been previously analyzed as a unique example of a stress system requiring a ranking of the Affix Faithfulness constraints over the Root Faithfulness constraints. I argue, however, that such idiosyncratic stress mechanisms are not necessary. Instead, I propose that accent assignment is cyclic: Underlying accent in the outermost derivational layer within the relevant domain wins. A central role in this analysis belongs to (i) the underlying specification of morphemes for accent, and to (ii) morpho-prosodic domains. The current proposal additionally offers an insight into the role of morpho-prosodic domains in the hiatus resolution strategies.
