Role and reference Grammar classifies verbs as states, activities, accomplishments and achievements based on states of affairs.Activities are categorized into some subclasses like consumption, creation, performance, etc.The current research aims to investigate the compatibility of the activity verbs classification presented by Van Valin (2005) with the activity verbs in the Persian language. To achieve this goal, the theoretical framework of Van Valin (2005) was used for data analysis, which means that 98 activity verbs were extracted from daily conversations, websites, and Persian books and placed in the category of verbs presented by Van Valin. The results of the research show that the classification of action verbs in the Persian language is not completely per the classification of Van Valin, as a new category of verbs called sensory verbs was added to the existing classification, and in verb valency of classes of motion, Static motion, performance and use of changes were made.
