This research analyzes the evolving language practice on social media platforms, with an emphasis placed on the role of language in forming online communities. Utilizing the Computer-Mediated Discourse Analysis (CMDA) framework, the research analyzes the impact of linguistic forms like the use of abbreviations, emojis, and visual elements like GIFs and memes on digital discourse. Social media has come to be a lively platform for not only personal expression but also community building because users create shared identities and share information. The study highlights the meeting place of language with sociocultural practice and how semiotics of the visual type, such as emojis, provide emotional resonance and intelligibility to digital communication. By examining the platforms of WhatsApp, Facebook, and Instagram, the study also finds opportunities and challenges posed by new forms of communication in terms of polarization, disinformation, and the loss of conventional writing skills. Social media allows for global interaction and cross-cultural communication but poses serious challenges in maintaining quality discourse and inclusivity. Lastly, this study illustrates the importance of digital literacy in dealing with the complexities of online communication, offering insightful remarks on how social media is transforming language, identity, and community in the technological era.
