Abstract: Discovering rules will lead to designing the scientific structure. Various people including Propp, Bremond, Greimas and Lévi-Strauss have tried to develop some principles and rules for stories in various literary genres since structuralism is the discovery of rules which create meaning in the narrative. In analyzing 100 Russian fairytales, Propp reached a specific model for studying stories which helps better understand the structure of stories. However, the model proposed by Propp is applicable to the stories of other nations as well. Propp has proposed four functions of the plot structure, including commitment, test, asking for help and failure. One of the methods for investigating the special characteristics of Iranian stories is to study them based on Propps morphology. Therefore, this study tries to analyze the stories of Fariba Vafi based on the framework of these four functions and to investigate the compatibility of these functions.
