As mobile-assisted language learning (MALL) continues to evolve, the notion of digital literacy must be reconsidered to account for the diverse and often fragmented ways in which learners engage with language through mobile devices. This entry outlines a set of interrelated literacies essential for effective participation in MALL, including technological, information, multimodal, social networking, and communication literacies. It further introduces newer domains—such as self-regulated learning, contextual literacy, transfer literacy, and attention management—that have become increasingly salient as learners navigate complex digital ecosystems. The entry argues that mobile literacy must extend beyond tool proficiency to encompass the strategic, reflective, and context-sensitive practices learners need to sustain development across time, tasks, and platforms. Special attention is given to the roles of generative artificial intelligence (AI) and augmented reality (AR), both of which challenge conventional assumptions about learner agency, content reliability, and the boundaries between formal and informal learning. Taken together, these literacies provide a pedagogical foundation for supporting learner autonomy, digital resilience, and critical engagement in mobile language learning.
