A New Approach of Compensatory lengthening Process in Persian language

This paper investigates compensatory lengthening processes in Persian language based on Stratal Optimality Theory. Method of this survey is descriptive-analytic. Since Optimality Theory can’t analyze intermediate levels of morpho-phonemics processes, the presented study evaluates morpho-phonemics analysis in Persian within the framework of Stratal Optimality Theory. Stratal Optimality Theory posits constraint evaluation at three distinct levels or strata: stem, word and phrase level. This multi-level variation of the original OT model may provide more economical and elegant explanations. In this survey, attraction, glottal consonant deletion and compensatory lengthening processes are analyzed within Stratal Optimality Theory and the order of constraints in each level are indicated. Further cross-linguistic and theoretical research into the Stratal OT model is needed to establish its universality and superiority to other models.
