This study sought to classify the constructions of pronominal verbs for the purpose of effective education of the pronominal verbs. To this end, the prototype theory was applied to classification of the pronominal verbs. From the perspective of this theory, the pronominal verbs are classified into 7 categories: reflexive, reciprocal, passive, no-agentive, autonomous, parasitic and intrinsic. And the prototype theory was applied to each of theses 7 categories again. The beneficial effects of this categorization are as follows. In the perspective of linguistics, this categorization shows the pronominal verbs very clearly and in detail including exceptional uses which the traditional classification misses. In the perspective of pedagogy, the classification on the basis of the prototype theory enables the learners to grasp the pronominal verbs with ease. Because this classification method is characterized by consistency and classifies pronominal verbs in a very systematic and organized way. This method has great educational effects on the way that these characteristics reduce the learners’ psychological consumption.
