In Second Language Acquisition (SLA) research, the term usage refers generally to a learner’s exposure to language, their production of it, and how they apply it in social interactions and deliberate practice. Though important in SLA research, usage does not have a standardized definition, with usage-based approaches defining it in various ways, and many focusing on a single aspect of language use. As a result, conducting comparisons across studies is challenging, and usage-based pedagogical practices could be misinformed. With a misrepresented concept of usage, second language (L2) educators employing usage-based teaching in the classroom may fail to prepare students for actual situations of L2 use. Usage in Second Language Acquisition: Critical Reflections and Future Directions (2024) aims to address this challenge by bringing together existing definitions and theorizations to provide a transparent description of usage and how it relates to L2 development. The editor’s goal is to understand the extent of agreement and disagreement of key theoretical constructs among approaches, to clarify how they are represented differently in literature, and to provide recommendations for future research in linguistics and pedagogy.
