The current study presents a methodology of teaching the connotations and nuances of the word Han (恨) to English-speaking Korean language learners. Since Han (恨) expresses unique and traditional aspects of Korean sensibilities, the goal would be for native English speakers to be able to understand the complexities of its meaning, in spite of the differences in culture background. To this end, research was done into how Han (恨) is translated into English, as there is no term in English with the same meaning. From these findings, a list of Korean vocabulary related to the meaning of Han (恨) was made to show its definitions in English. In addition, a survey was conducted on 42 Americans to find out how English speakers understand Han (恨). As a result of this research, the current study demonstrates the need to teach the meaning of Han (恨) to Korean language learners from English-speaking countries, and suggests a teaching methodology which follows the order of Pre-Class, In-Class and After-Class study based on the Flip-Learning model.
