Abstract: This study examines the influence of social media language on the formal academic writing of undergraduate students in Cameroon. Students have made digital platforms an important part of their everyday lives (Crystal, 2006; Barton & Lee, 2013). They are used for learning, chatting with friends, watching the news, entertainment, business, etc. Platforms like WhatsApp, Facebook, TikTok, and Instagram are the main ones, giving rise to a new form of computer-mediated communication defined by neologisms, abbreviations, and frequent code-switching.
