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.

什麼時候才有語言和文字的？可以認為誰都說不清楚。我國的語言學家們杜撰了“語先文後”論，但卻自相矛盾。這是什麼道理呢？語言學是一門科學的學問。科學要講的是依據，不能亂加臆斷。如果沒有依據，那只能叫做假說。假說也不能亂說，要有個推理的順序，不能出邏輯錯誤。凡不合於邏輯的，也可以從其歷史發展的推理中認識其混亂。我國語言學家往往會持權反駁批評者，說他們不懂語言學的ABC，壓制他們的批評。語言學的ABC是什麼？我認為是歷史、規律和基本概念。本文從“語先文後”的爭論中悟得語言學中的ABC，從信號、符號兩個概念發展的歷史發展中推求出語言、文字發展的道理；也是從符號、信號兩個概念的分析中推求出兩個概念混淆的原因，同時對語言學中的其他一些基本概念如：符號系統、信號系統、書面語言、文章等做了認真的區分。
