This article examines the digital language practices in a Facebook group of seven British migrants, who live in Greece and have applied for Greek citizenship, throughout March 2021, in the aftermath of the United Kingdom’s decision to leave the European Union. More specifically, it uses online ethnography to analyse the ways with which group members use language and construct identity through their public posts and comments. Although research into the digital language practices and identity construction of Greek migrants has been carried out, no such research exists in the case of British migrants residing in Greece. It will be shown how group members’ use of both Greek and English, as well as creative examples of code switching for the purpose of conveying concepts to other members, offers insight into how the group under study use language to position themselves in relation to both Greece and the Greek citizenship application process, as well as to other members who possess varying degrees of linguistic competency in Greek.
