Vowel Harmony in the Optimality Theory-Candidate Chains and the Optimal Interleaving Models: A Case Study in Kalhori Kurdish(مقاله علمی وزارت علوم)

Two of the models in the Serial Optimality Theory in which derivational paths compete and are evaluated by Prec(a, b) family of constraints are Optimality Theory- Candidate Chains (OT-CC) and Optimal Interleaving (OI). The former operates exclusively at the level of phonology, while the latter postulates the interplay between morphology and phonology. This article presents a case study of vowel harmony in Kalhori Kurdish that necessitates a level where phonological and morphological processes alternate to account for both the application and lack of application of a phonological process. In Kalhori Kurdish, the features of [o] are spread regressively all the way to the leftmost edge of the verb; however, this is not the case when the coordinating conjunction clitic [=o] is added to the verb. The analysis of the data collected from 15 Kalhori Kurdish speakers revealed that OT-CC cannot simultaneously explain the root-prefix vowel harmony and the absence of this process between the clitic and the verbal ending, unless the morphological information is duplicated at this level. However, benefiting from the possibility of morphological processes alternating with the phonological ones, the OI model successfully explains both the presence and the absence of the vowel harmony
