Prototype theory provides an effective way for polysemy learning. In the learning process, learners should pay attention to the study of basic categories of vocabulary, strengthen the understanding of the meaning of the vocabulary prototype, and pay attention to the metaphorical significance of words. Based on the analysis of the category prototypes and motivations of polysemy, this paper explores the effective ways to learn polysemous words to promote learners’ learning of polysemous words.
