Usage Patterns of Native Korean and Sino-Korean Word in a Korean Newspaper Corpus for Korean Language Education: Focusing on the Distinction between ‘(chaegeul) ikda’ and ‘dokseo(hada)’

This study aims to analyze the differentiate the usage patterns of the native Korean verb ‘(chaegeul) ikda’ and ‘dokseo(hada)’. For this purpose, examples were collected from the National Institute of Korean Language Korean Newspaper Corpus (2021, ver. 1.0) and examined through an inductive analysis. On the basis of the corpus findings, five criteria for distinguishing near-synonymous expressions were established: (1) degree of concreteness of the act, (2) purposiveness, (3) semantic extensibility, (4) types of contexts and (5) constraints of lexical use. The results show that ‘(chaegeul) ikda’ not only denotes the act of reading books and other texts, but also exhibits semantic derivation and extension in expressions such as ‘heureum-eul ikda (to read the flow)’, ‘jeongse-reul ikda(to read the situation)’, and ‘cho-ikgi(countdown)’. In contrast, ‘dokseo(hada)’ refers to a sustained and comprehensive learning activity and is frequently associated with purposes such as cultivating cultural literacy or enhancing thinking skills. It is especially widespread in noun-centered compound forms such as ‘dokseoyul(reading rate)’, ‘dokseo-toron(book discussion)’, and ‘dokseo-seupgwan(reading habits)’. Despite this wide range of formations, the object of ‘dokseo’ is found to converge on printed books. These findings indicate that, even when native Korean and Sino-Korean expressions appear to be semantically similar, they exhibit differentiated patterns of use in terms of collocation, constraints, and discourse functions. This study is significant in that it differentiated near-synonymous expressions on the basis of corpus data and provides foundational resources that can help Korean language learners use Korean vocabulary with greater precision.
