This study tries to analyze the basic and extended meanings of the Korean verb mek-ta 'to eat' from a cognitive point of view. The most basic meaning of the verb is 'to pass food and others through the mouth into the stomach'. This meaning has been extended to other intransitive and transitive verb meanings and auxiliary verb meanings. When presenting the verb to learners of Korean as a Foreign Language (KFL), it should be presented so that learners themselves can infer the extended meanings using a semantic network. To this end, uses of those words meaning 'to eat' in the native languages of KFL learners should be investigated, and common meanings with the Korean verb should be identified. Then, we can create a semantic network of the senses of 'to eat', a network of the basic meanings and extended meanings of mek-ta in Korean and corresponding verbs in other languages.
