The use of digital tools for second and foreign language lexical learning is increasingly popular and research in this area is constantly expanding. However, little has been written about specific criteria that could be used to identify tools with high-quality lexical input, as available checklists and frameworks for digital media tend to neglect detailed analyses of the vocabulary domain. This article addresses this issue by presenting the Checklist for Evaluating Digital Resources for Lexical Learning (DigiLex), which combines important digital language learning criteria with an extensive evaluation of lexical content. The checklist is both theory-based and user-friendly, aiming to fill a gap between theory and practice in the field of digital lexical learning. The article discusses the theoretical basis of the checklist and integrates the results of a small pilot study with pre-service and in-service teachers, emphasizing feasibility in everyday learning and teaching. By providing an easy-to-use tool for identifying suitable digital resources, the DigiLex checklist aims to support language learners and teachers in self-regulated lexical learning.
