In modern times, the popularity of social media and online communities play an important role in both daily life and language learning. Social media and online communities have become integral to modern life, offering unique opportunities to transform English Language Teaching (ELT). This literature review examines how the affordances provided by these platforms are reshaping the current landscape of ELT through an ecological perspective. Specifically, the study investigates their influence on teaching and learning practices, focusing on how these affordances foster authentic language use, collaboration, and personalized learning experiences. Additionally, the review explores the implications of these affordances for teachers’ strategies in designing dynamic, multimodal learning environments that extend beyond traditional classrooms. By synthesizing findings from recent research (2014–2024), the study highlights the transformative role of social media and online communities in creating enriched affordance environments. These platforms enable greater learner autonomy, cultural awareness, and engagement. The study also identifies practical recommendations for educators to integrate these tools effectively while addressing challenges such as digital literacy and privacy concerns. This review provides a comprehensive understanding of how digital affordances are shaping ELT and suggests strategies for leveraging them in innovative and sustainable teaching practices.
