A Study on the Usage Patterns of the Support Verb 'Nada' by Japanese-speaking Korean Learners through the Korean Language Learner Corpus

The purpose of this study is to analyze the usage patterns of the support verb "Nada" by Japanese-speaking Korean learners through the Korean learner corpus in comparison with native Korean speakers, focusing on descriptive nouns by meaning type and frequency.This study further aims to anticipate challenges that Japanese-speaking learners may encounter due to linguistic contrasts with Japanese.For this analysis, the <Korean Basic Vocabulary Meaning Frequency Dictionary> was used as a reference to compare data from the <Learner-Form Annotated Corpus> of the National Institute of the Korean Language and four commercially published Korean-Japanese Dictionaries.The results indicate that native Korean speakers most commonly used descriptive nouns related to "smell/sound/scent" whereas Japanese-speaking learners predominantly used nouns such as "memory/thought/doubt" The variety of descriptive nouns used with "Nada" was greater among native Korean speakers (44 types) than Japanese-speaking learners (21 types), indicating a more limited range among the learners.These differences suggest that Japanese-speaking learners are influenced by their native language, leading to restricted usage patterns.These differences in high-frequency vocabulary and the diversity of descriptive nouns combined with support verbs reflect linguistic distinctions between Korean and Japanese, underscoring the need for targeted instruction.Teaching the diverse contexts of "Nada" may help learners expand their understanding and use.Furthermore, integrating corpus-based methods in Korean language education can provide learners with authentic examples, improving their use of support verbs.
