‘一’字관련 불교 어원의 중국어 성어 小考

Numbers are very necessary in our daily life. And people gradually tried to explore by connecting numbers and nature and combining the providence of the universe. Thus, the numbers have a variety of rich philosophical implications. In this text, I analyzed the meaning of the Buddhist etymology related to the word ‘一’, examined the rhetoric expressions, and analyzed the use of the idioms In the analysis of the meaning of idioms, I looked at the original Buddhist meanings as well as the meanings used in modern Chinese. As a result, some of the original Buddhist meanings were used as they were in modern Chinese. However, some of the meanings have changed or been derived from others, and even some meanings have been used in completely different meanings. By looking at the formation of the meaning of idioms and the current state of use, it can help to understand the overall development process of the meaning of idioms. In the analysis of idioms' rhetorical expression, I analyzed it by dividing it into parables, overlapping, and codified expressions. By using these rhetorical expressions, the meaning of idioms can be conveyed in an implicit and vibrant way. As a result of analyzing the frequency of use of idioms related to the word ‘一’, 一心一意(Wholeheartedly in English) and 独一无二(Unique in English)are the most used in modern Chinese, and 一文一武(The text refers to academic success, and the military refers to success in the army. In English) and 一切万物(Everything in English) are the least used. By area, it shows the highest utilization frequency in multi-domain(多領域) and the lowest utilization frequency in literature(文學). Through the research of idioms related to the word'一', I hope that the philosophical meaning of the word'一' will serve as an opportunity to practice in human daily life, and will contribute to the expanding study of the meaning of number idioms.
