Jaemulbo (Caiwupu) is a dictionary rich in words, and has the nature of an encyclopedia. Giving a brief description of the collection and interpretation of the terms of plants and animals and observing the acceptance of the Chinese characters and words in the Korean Peninsula, this article singles out four myeongmul (meibutsu) words for textual research in order to observe the characteristics of vocabulary spread to ancient Korea. It has four main objectives. The first is to support the authoritative theory. The second is to ignore character and word relationships that lead to errors although scholars know that glyphs can be used universally. The third is to be cautious not to follow them blindly. The last is to influence the culture of the nation’s famous objects. It is expected that this research can make a significant contribution to the future studies on the spread of Chinese characters.
