ABSTRACTApplied linguistics is a field concerned with issues pertaining to language(s) and literacies in the real world and with the people who learn, speak, write, process, translate, test, teach, use, and lose them in myriad ways. It is also fundamentally concerned withtransnationalism, mobility, andmultilingualism—the movement across cultural, linguistic, and (often) geopolitical or regional borders and boundaries. The field is, furthermore, increasingly concerned withidentityconstruction and expression through particular language and literacy practices across the life span, at home, in diaspora settings, in short-term and long-term sojourns abroad for study or work, and in other contexts and circumstances. In this article, I discuss some recent areas in which applied linguists have investigated the intersections of language (multilingualism), identity, and transnationalism. I then present illustrative studies and some recurring themes and issues.
