This issue engages with contemporary sociological debates on reflexivity, youth, and late modernity. Drawing from the ontological and epistemological lens of linguistic ethnography, the contributors describe different indexical forms of language use (linguistic styles, discourse registers, small narratives, moral stances, metacommentaries and semiotic norms), in the context of their participants' life trajectories with the aim to: (a) offer a fresh view of the linguistic/discursive resources that young people mobilize to make their way through the world; (b) engage with existing knowledge in the social sciences through revisiting well-established constructs in socio-culturally oriented applied linguistics (habitus, social field, structuration, modes of reflexivity, cultural capital and social class), in light of the cultural conditions of late modernity; and (c) suggest some implications for applied researchers and practitioners. The issue presents data collected in US, Singapore, Hong Kong, Spain, Finland or Belgium, and includes research participants from a wide range of socioeconomic backgrounds.
