Abstract

Inflected words in Finnish show a range of interdependent stem and suffix alternations which are conditioned by syllable structure and stress. In a penetrating study, Anttila (1997) shows how the statistical preferences among optional alternants of the Genitive Plural can be derived from free constraint ranking. I propose an analysis which covers the rest of the nominal morphology and spells out the phonological constraints that interact to produce the alternations, and show how it supports a stratal version of OT phonology.
