Exploring Identity Construction and Language Use Among English Language Learners in Online Communities: An Integrative Review (2004-2024)

This article explores how English language learners (ELLs) negotiate identity and language use across diverse digital environments such as social media, online forums, and language learning platforms. Drawing on sociolinguistic and educational perspectives, it critically reviews studies on digital identity, online communication, and technology-enhanced language learning. Using an integrative qualitative approach, it synthesizes findings from empirical and theoretical research. The analysis highlights how ELLs perform and co-construct identities online through choices of language, dialect, and self-presentation, including profile curation and engagement in affinity groups. Practices such as code-switching, translanguaging, and the use of internet slang are shown to serve as powerful tools for both communication and identity expression, helping learners build confidence and a sense of belonging in global communities. The article also discusses challenges such as identity fragmentation and cultural bias. It concludes by emphasizing the pedagogical importance of recognizing online spaces as meaningful contexts for language development, intercultural competence, and identity negotiation.
