The purpose of this study is to identify the polysemous characteristics of academic vocabulary, examine its meaning, and derive relevant educational implications. To this end, 232 academic vocabularies were selected based on Hwang Sung-eun(2017), and the vocabulary list including the basic meanings and specialized meanings for each vocabulary was prepared. As a result, it was confirmed that the academic vocabulary with one or more specialized meanings in addition to the basic meanings accounted for a majority: 88%. Since then, an expert investigation was conducted on 163 specialized meanings in seven academic fields with high frequency, and the meaning of 134 final academic vocabularies was analyzed. The analysis confirmed that having a specialized meaning in addition to the basic meaning can be managed with in Korean language education for academic purposes before entering the major. Specifically, the results suggested that if the distance between the basic meaning and the specialized meaning is close, they can be taught and learned simultaneously as per the academic field, if not, caution must be exercised when inferring the specialized meaning from the basic meaning. This study is meaningful in that it has expanded the existing discussion related to academic vocabulary to incorporate a broader perspective. (Kyung Hee University)
