the position of stress in persian bound morphemes

stress refers to the degree of force used in producing a syllable. all of the words in lexicon regardless of the apparent structure and the number of their syllables have their own stress. given that the regularities governing stress assignment in persian depend on the type of lexical category and that persian speakers have a tendency to assign stress at the end of words, the goal of the present paper was to explore the patterns of stress assignment in persian bound morphemes under the optimality theory. data analysis was done by ot soft software (version 2.3.2). with regard to the data, it was concluded that the apparent difference between bound morphemes stress was due to the prosodic level at which they appear. the set of constraints involved in the analysis of persian stress included: align r/l, wrap & clash.
