By examining specific articles on the subject, this study explores how language policies and use in Luxembourg individually and collectively inform the complex intersections of multilingualism/ecology, identities/agency and nationalism/ideology. These studies suggest theoretical and policy implications by investigating the topics of agency, ideology and ecology as these unfold in everyday situated practices. The papers specifically offer contributions to our understanding of multilingualism, transnational identities, and nationalism. The study concludes by suggesting the need for policies relevant to diverse linguistic and ethnic identities which, thus, foster educational and social equity.
