Language and Migration

This article examines the field of language and migration, highlighting its emergence as a distinct area of study within sociolinguistics and applied linguistics. Organized around key themes—mobility, superdiversity, and the redefinition of linguistic repertoires—it begins by exploring how these concepts influence linguistic resources, practices, and identities, shaping communication in diverse migratory settings. The discussion then shifts to the evolving nature of linguistic repertoires, emphasizing their flexibility in adapting to various social, cultural, and digital contexts. The impact of digital spaces on migrants' communication is also examined, introducing concepts such as repertoire assemblage, which illustrate the integration of linguistic and semiotic elements. Further analysis addresses how language ideologies, indexicality, and scale affect the value and use of migrants' linguistic resources. The concluding section considers the role of language in identity construction, highlighting how migrants navigate and reshape their identities through language.
