The increase of digital communication has heightened the importance of punctuation in conveying meaning. Punctuations play a pivotal role in enhancing communicative meaning, yet their use, or lack thereof, in digital writing remains understudied. Despite the growing body of research on punctuation as a meaning-defining device in written communication, there has been a notable lack of research on the impact of punctuation on communication in digital writing. Drawing on theories such as Kress's multimodal theory, speech act theory, and communication accommodation theory, this research explores how punctuation affects message interpretation, with a particular focus on its absence, presence, and misuse. Employing a qualitative approach and content analysis method, thirty written digital posts were randomly selected and studied, with ten posts from each of Facebook, WhatsApp, and Twitter. Findings reveal that punctuation negligence and abuse are common across the digital interaction space, resulting in an overburdening cognitive load on readers, incoherence, and miscommunication. Common punctuation errors discovered range from omission and misplacement to excessive and inconsistent use of standard marks. The study also highlights the adaptive nature of punctuation in digital writing, where users modify their punctuation styles to align with discourse communities, sometimes at the expense of clarity. Given the findings, the study recommended awareness of punctuation, mindful writing practices, and other strategies for improving digital communication, emphasising the need for clear punctuation to aid understanding of digital discourse.
