Eating is the most basic action of human survival. This paper makes a contrastive study of the polysemy of the basic verbs expressing this action in Korean and Chinese. It is found that the two verbs derive some similar semantics based on the common cognitive style of human beings, but also because of the differences in the interpretation of the conceptualization process of the action, they produce some different derived semantics. Through comparative analysis, we find that the conceptual schema of Chinese verb “eat” is composed of the elements of “enter-chew- swallow”, which highlights the chewing action in the mouth, and its derivative meaning also shows the characteristics of experience and process. The conceptual schema of Korean verb “먹다” is composed of some elements as “enter-swallow- conserve”, which highlights the preservation state in the abdominal cavity, and its derived meaning also shows the characteristics of experience and result.
