The present study is an investigation of consonant deletion in Persian final clusters. To do this 1500 words, at least 600 of them one syllable were investigated. The study has classified the clusters into two classes, with or without consonant deletion (stable or instable cluster).The consonants of the clusters were analyzed based on the sameness and distinctions of investigated features. The study has indicated that the number of clusters with consonant deletion is less than those without. There is a direct relationship between the sameness of values and stability of clusters. In stable clusters the same values for obstruent, continuant and voice in general, are significantly less than those with different ones. The difference between the number of + F and –F for continuant and voice are statistically significant while for obstruent is not. The study has also indicated that in addition to features phonotactic as well as word structure is also effective. In the present study consonant deletion in Persian has been analyzed in the frame work of Optimality theory. In this way it has been argued that marked constrains hierarchy stand above faithful ones.
