This study is about meta-language used for teaching the Korean language in Serbia, where it is not a native language. This study examined meta-language for teaching preferred by Korean language learners of Serbia and explored efficient methods of meta-language use for teaching. First, meta-language and meta-language for teaching were discussed, and meta-language for Korean language teaching was defined. After setting up the research question and hypothesis, a survey was conducted on Korean language learners at the University of Niš in Serbia to determine their preferred meta-language for teaching. According to the survey, many learners wanted to take classes in ‘Korean-Serbian languages.’ Beginner and intermediate learners of vocabulary, grammar, and conversation preferred ‘Korean-Serbian’ meta-language for teaching, and advanced learners preferred ‘Korean’ meta-language for teaching. Based on such grounds and existing theories, this paper proposed a usage model of meta-language for teaching in beginner, intermediate, and advanced Korean language classes in Serbia and presented the necessity for fostering professional Korean language instructors overseas.
