On 1 July 2021, I participated in a panel on 'Diachronic pragmatics: New perspectives on spoken English from the twentieth century to today' convened by Elisabeth Reber (Univ. of Heidelberg/ Univ. of Würzburg) and Andreas Jucker (Univ. of Zürich) at the 17th International Pragmatics Conference (IPrA). My talk examined emergent pragmatic conventions, specifically inclusive vs. exclusive multilingual practices, in three Transient International Groups.
