A Study of Chinese Language Morphemes in the Perspective of Second Language Acquisition (1998-2024)<br>—Based on Bibliometric Analysis

As morphemes are the smallest phonetic and semantic word formation units in Chinese, the study of morphemes has always been an important part of Chinese language acquisition research. Taking Chinese morphemes as the research object, this paper systematically examines the research status, research themes, research hotspots, research frontiers, and research methods of Chinese morphemes from the perspective of second language acquisition, based on 145 periodical literatures in the CNKI database in the last thirty years, and utilizes CiteSpace 6.3.R1 to conduct the metrological analysis. Currently, the research has problems such as a single research method and insufficient interdisciplinary integration. Future research can deepen the research by expanding the research object, deepening the research content, integrating the research methodology, and enhancing the interdisciplinary integration in order to promote the in-depth development of the research in this field.
