A Study on the Usage Patterns of Connective Endings by Chinese Learners of Korean: Focusing on Differences by Proficiency Level

Objectives The study analyzed the usage patterns and error aspects of connective endings by Chinese learners of Korean based on their proficiency levels, utilizing the morphological annotated corpus and error annotated corpus from the National Institute of the Korean Language. Methods In this study, at the first compiled a list of connective endings commonly presented in the textbooks of different levels at Korean language institutes. Then, it collected data on the frequency of these connective endings used by Chinese Korean language learners at each proficiency level from the National Institute of Korean Language's morphologically annotated corpus, and analyzed the error frequency by proficiency level using the error annotation corpus. Results The use of connectiveendings presented in the language school textbooks is very active, with ‘-고’ being the most frequently used connective ending across all proficiency levels, and replacement errors occurring most often. Conclusions In this study, starting from textbook analysis and examining the morphological annotated corpus and the error annotated corpus, I believe it is significant to consider the overall usage patterns of connective endings among Chinese learners of Korean.
