초록

This study aims to empirically validate an inventory of similar Korean connective endings by analyzing learner error data. While previous research has largely relied on theoretical similarity and instructors’ experiential knowledge in selecting target items for Korean grammar education, this study focuses on learners’ actual substitution errors to evaluate the appropriateness of such selections. To this end, 6,963 instances of connective ending substitution errors were extracted and analyzed from a large-scale Korean learner error corpus, and core areas of learner confusion were identified based on frequency distributions. The analysis revealed that substitution errors among connective endings exhibit a multilayered pattern of interaction between semantic-functional proximity, morphological constraints, and syntactic structure. By comparing existing similar grammar lists with learner error data, the items were classified into three categories: those where theoretical predictions and empirical evidence converge, those that were over-selected based on theoretical criteria alone, and those that were newly identified from learner errors but absent from existing lists. By validating similar grammar inventories through empirical evidence drawn from learner errors, this study provides a more precise basis for determining instructional priorities and selecting target items in Korean grammar education.
