Abstract

L3 acquisition is gaining prominence in the academic community. The cardinal aim of this study is to conduct a bibliometric analysis of research on L3 acquisition. 425 documents from the Scopus database were analyzed with Bibliometrix. To gain a general and systematic overview of research on L3 acquisition, we grounded our study on three main levels of bibliometric analysis: performance analysis, collaboration analysis, and thematic map. By doing so, we identified the most influential sources, authors, affiliations, countries, and documents, the scientific network among different constituents, as well as the evolution of research trends. The results suggest that L3 acquisition has experienced three periods: initial phase, development phase, and burst phase. The results also indicate that: The International Journal of Multilingualism is the most steady source contributing to this field. Relevant contributors for each period are recognized, including established and emerging researchers. European countries such as Spain, United Kingdom, Norway, Sweden, and Poland are at the forefront of publication. Collaboration increases over time but is becoming increasingly oriented in European and Anglophone countries. The research hotspots have shifted throughout time, encompass a broad range of fields, and continue to grow. The study results provide insights into the evolving trends of L3 acquisition studies and data to assist researchers in identifying research gaps.
