Contact linguistics takes the series of linguistic phenomena in the process of language contact as the research content, and explores the changes of the languages and their results. When language contact occurs between Chinese and Korean, the linguistic phenomena occurring in the aspects of phonology, syntax, vocabulary, and characters are one of the important results. Sino-Korean Rhyme Dictionaries are language tools that are mainly arranged by rhyme. Such dictionaries annotate the pronunciation of Chinese characters, correcting the incorrect pronunciation of Chinese characters in Korea, and occasionally interpreting the meaning, and recording some glyphs of variants, which provide the convenience for extracting poems and lyrics, as well as reciting rhyming characters. From the perspective of the developmental history of Chinese dictionaries in Korea, rhyming books are the beginning of Chinese dictionaries in Korea, which have abundant content and significant value, and are indispensable and valuable materials for the study of Chinese-Korean contact linguistics.
