Abstract

In Stratal OT, morphology and phonology are stratified and interleaved, as in traditional Lexical Phonology (Mohanan 1986), but the strata (Stem, Word, Postlexical) are characterized by systems of parallel constraints. The output of each morphological operation is submitted to the phonological constraints on its stratum: stems must satisfy the stem phonology, words must satisfy the word phonology, and Phrase must satisfy the phrasal phonology.1 For example, an affix which is added to stems to form words would enter into the derivation in the following fashion.
