In this study, a researcher transcribed Korean negation sentences presented on four episodes of the [Love of 7.7 Billion] and analyzed the discourses of foreign panel members by focusing on Korean negation sentences. The aims of this study are to (1) analyze types and accuracy of Korean negation sentences in foreign panel members’ discourse and (2) present pedagogical implications for efficient Korean education on negation sentences. This study was launched as an attempt to analyze how correctly and variously foreign panel members in the program use Korean negation sentences in their discourse. Since discourse is closely related to the ordinary life of humans, discourses which appeared on the [Love of 7.7 Billion] would be suitable data to analyze since it is a discussion-based program. Therefore, discourse is useful from a pedagogical standpoint to look into the Korean language proficiency of them. Through discourse analysis, several implications were found. (1) foreign panels tended to use short negation sentences rather than long negation sentences; (2) panels’ use of Korean negation sentences was not various; (3) panels divided Korean negation sentences into often-used negation sentences and rarely-used negation sentences; (4) the use of negative polarity was not found that much.
