This article advocates for a ‘sociolinguistics of deglobalization’ that focuses on the sociolinguistic impacts of major shifts in the world system that have taken place since 2008 and have become particularly salient amidst the covid pandemic. Drawing on case studies of China, Indonesia, Ethiopia, and Nigeria, we describe the period after 2008 as an emerging post-neoliberal epoch characterized by the intensifying of state power, constrained resistance, differential inclusion, and organized abandonment. Our article explores the theoretical, methodological, and ethical challenges of researching the sociolinguistic impacts of these developments. We also argue that our discipline's dominant approach to global-scale analysis—the sociolinguistics of globalization—has impeded our ability to perceive the emerging dynamics of deglobalization. Our call for a sociolinguistics of deglobalization is offered as both a provocation and invitation to our discipline to engage with the rapidly changing nature of world politics.
