With the accelerated pace of legal globalization, the study of Chinese legal terms has received great attention and promotion. As an important part of legal research and practice, the accuracy and standardization of Chinese legal terms directly affect the effective implementation of laws and the smoothness of international cooperation. This study analyzes the development process, usage context and evolution rules of Chinese legal terms in the last hundred years (from 1923 to 2023), excavates the connotation and evolution path of legal terms, explores the core factors affecting the change of legal terms, and discusses the correlation between the process of Chinese legal reform and the evolution of legal terms. The development of Chinese legal terms is closely related to the reform of China's legal system, which reflects the gradual improvement and internationalization trend of China's legal system. Based on the comprehensive use of comparative legal language and semantics methods, this study predicts the possible trends and challenges of the future development of legal terms, and provides a theoretical basis for the standardization and international exchange of legal terms in China, provides valuable theoretical data for the field of legal linguistics, and expands a new perspective for the study of legal terms.
