This document discusses how context influences language use. It identifies six key contextual factors: setting, participants, activity, channel, code, and subject matter. It then provides examples of how each factor can shape language, such as institutional settings influencing formality or the number of participants affecting unison speech. The document also notes that when people from different backgrounds interact, their language may converge or diverge depending on rapport. Overall context, including the situation, individuals involved, communication medium, and task, significantly impacts communication.
