Analyzing the Realization Patterns of Interpersonal Functions in Dialogues of Intermediate Korean Language Textbooks

Objectives This study aimed to analyze the realization patterns of interpersonal functions in dialogues of inter-mediate Korean language textbooks from the perspective of Systemic Functional Linguistics. Methods This study analyzed the interpersonal functions and their realization patterns in dialogues from Korean intermediate integrated textbooks published in the late 2000s. By establishing two main analytical categories—mood system and mood metaphor—and conducting distribution and realization pattern analyses for each cat-egory, we explored the linguistic characteristics of textbook dialogues from the perspective of Systemic Functional Linguistics. Results In the textbook dialogues, declarative sentences were most frequent, followed by interrogative, imper-ative, and suggestive sentences. For honorific forms, the combination of ‘하십시오체+해요체’ was most common, followed by ‘해라체+해체’, with the ‘하게체’ being least frequent. For mood metaphors, interrogative forms func-tioning as statements or commands were most frequently observed. Conclusions The study confirmed that the analyzed Korean textbook dialogues accurately reflect the language us-age patterns of native Korean speakers, and demonstrated the effectiveness of the Systemic Functional Linguistics approach in textbook analysis.
