It focuses on the use of the discourse marker so in prefacing summaries as a strategy for claiming epistemic primacy, with particular attention being paid to so's multimodal accomplishment. Taking an interactional sociolinguistic approach, we bring together simulated and real-life trauma emergencies and zoom in on the role of the institutionally defined team leader.enArticle
