A Study on the Semantic Function of the Korean Connective Ending ‘ (n/neun)dago'

In this study, I examined the semantic function of the Korean connective ending ‘-(n/neun)dago’ from the perspective of Korean grammar education. First, I reviewed the semantic function of connective ending ‘-(n/neun)dago’ presented in Korean dictionaries, Korean grammar education materials, and Korean textbooks. Second, I confirmed that the results of Korean linguistic research related to ‘-(n/neun)dago’ from the perspective of grammaticalization. Third, it was discussed that in order for Korean teachers to teach and learn ‘-(n/neun)dago’, they must first understand its semantic function. Fourth, I looked at the patterns of exchange between ‘-(n/neun)dago’ and grammatical items with similar semantic functions. Fifth, I looked at the ambiguity of the boundary between the semantic functions of the ‘-(n/neun)dago’. In the end, I can confirm that the semantic function of connective ending ‘-(n/neun)dago’ should be judged based on the logical and semantic relationship between the preceding and following clauses.
