This paper is based on the view that hangeul is itself one of the most significant culture codes of Korea. According to Hunminjeongeum, hangeul is created upon the traditional Korean cultural ideas such as Yin-Yang and Five Elements code. Thus, for more effective learning of hangeul and Korean traditional culture, especially for the students from western cultures, first thing would be not so much to teach them technical or theoretical features of hangeul as to let them acquainted with Korean culture codes explicated in Hunminjeongeum. This can contribute to their more effectively overcoming the language ‘interference’ coming from the difference between their native language and hangeul. Moreover, letting the learners exposed to living cultural features which reflect hangeul’s culture codes would help them see hangeul not just as a symbolic sign system but as one of the most effective living communication tools through which they can appreciate not only hangeul but also diverse traditional Korean cultures.
