This study investigates the use and socio-cultural significance of the expression “OTW” (on the way) within Indonesian digital communication. As informal language becomes increasingly influenced by digital interaction, it is essential to examine how expressions such as “OTW” evolve in meaning and function. Framed within a sociolinguistic perspective, this study explores how “OTW” extends beyond its literal interpretation to convey social intent and reflect cultural values, particularly those emphasizing social harmony over punctuality. A qualitative research design was implemented, combining semi-structured interviews with a literature review. Participants were selected across generational groups to capture diverse patterns of usage and interpretation. The findings indicate that “OTW” often operates as a communicative strategy rather than a factual statement, enabling users to manage expectations, reduce social tension, or maintain face in various digital contexts. However, this shift in meaning may result in miscommunication, particularly in professional or intercultural settings where punctuality is strictly valued. This research highlights the dynamic, adaptive nature of digital language and the need for communicative awareness in online interaction. The study contributes to a deeper understanding of how informal digital expressions reflect broader socio-cultural dynamics and suggests further inquiry into their impact on interpersonal trust, accountability, and cross-cultural communication.
