THE NOTION OF SUPER-DIVERSITY was proposed by Vertovec (2007) to address the changing nature of global migration characterized by “a dynamic interplay of variables among an increased number of new, small and scattered, multiple-origin, transnationally connected, socio-economically differentiated and legally stratified immigrants”(1024). The intention behind the introduction of this notion, as Meissner and Vertovec (2015) point out, is not to stress the existence of more ethnicities, but to recognize “multidimensional shifts in migration patterns”(541). This chapter aims to contribute to the debate on multidimensional shifts in migration patterns through an examination of multilingual practices, socialization and negotiation of cultural values among members of a family of second-and third-generation immigrants. The findings are based on a three-year study investigating mealtime routines and interactions of a multilingual Arabic-English-speaking family in London. Informed by a sociolinguistic, language socialization theoretical framework (see Ochs and Schieffelin 1984), this chapter focuses on the strategic use of address terms in the course of mealtime interactions (ie, the way family members employ address terms to achieve a range of interactional goals). These analyses will help us better understand the role of multiple languages in the process of socialization and bring to the fore issues of cultural values and social relationships in the context of super-diversity.
