Although word lists have generated a great deal of attention from researchers, there has been no comprehensive review of the applications of word lists in second language learning and teaching. This article reviews the development, validation, and applications of 50 word list studies that were published and discussed in major international peer-reviewed Applied Linguistics and TESOL journals from 2013 to 2023. It shows that the methodology of word list development and validation has become more sophisticated and word list developers can see many potential applications of their lists in research and pedagogy. However, most applications of recently developed word lists have been restricted to the BNC/COCA lists developed by Paul Nation, and little is known about the degree to which most word lists have been used in pedagogical contexts. Our review indicates several directions for future research on word lists, including exploring the impact of published lists on pedagogy, replicating word list studies for learners in underrepresented contexts, and developing sustainable, low-cost methods of developing word lists to allow teachers and learners to create lists serving their own needs.
