This study examines the role of social media platforms, such as Instagram and WhatsApp, in shaping English language use among English Language Learners (ELLs) in Kuwait. Ninety-two undergraduate students from the Public Authority for Applied Education and Training participated, providing survey data on social media usage patterns and real language samples, analysed through descriptive statistics and thematic methods. Semi-structured interviews with educators and students offered deeper insights into the perceived impact of these platforms on language development. Findings reveal frequent use of new vocabulary, abbreviations, and emojis, reflecting social media’s direct influence on informal communication styles and lexical innovation. The study highlights the multifaceted dimensions of this impact from linguistic and social perspectives, portraying social media as a dynamic platform for linguistic socialisation in line with theories that view language as an adaptive system responding to societal changes. However, despite the noticeable benefits of social media in fostering regular English practice, the widespread prevalence of informal linguistic patterns raises significant concerns regarding its potential impact on formal language skills and grammatical accuracy. In light of these findings, the study highlights the gap between informal and academic communication standards, emphasising the importance of integrating social media into directed educational contexts. Such integration aims to achieve an effective balance between informal linguistic innovations and observing formal language norms. Additionally, the study recommends adopting a more conscious pedagogical approach to enable students to maximize the benefits of social media while safeguarding the quality of their academic performance.
