This article discusses the role of affect in diasporic belonging, especially when a community is affected by conflict, tracing the ways it circulates in and through discourses and interactions across different generations. Drawing on a linguistic ethnographic project on Greek-Cypriot diaspora, and following recent calls for paying more attention to affect in sociolinguistic analyses, it analyses the communicative dynamics of diasporic affect. Understanding diasporic affect as the circulation and communication of affects/emotions between individuals within a diasporic space, which is—to an extent—regulated by community norms, we analyze the discursive and communicative mechanisms participants used to navigate emotional norms about collective memory, conflict, and diasporic identifications. At the same time, we show how these mechanisms are productive of subjectivities that could either reinforce, disrupt, or redefine these norms. In doing so, we discuss the political implications of diasporic affect and the rules governing its expression and enactment in discourses and communicative practices.
