Adolescents, particularly those in multiethnic, multilingual communities, have become central to sociolinguistic research in the variationist tradition (Cheshire, Nortier & Adger 2015). In several studies of adolescent speech in European urban centres, the same set of Arabic-derived epistemic phrases, namely wallah, wallahi and related phrases meaning ‘swear’, appear to be in use (see, e.g., Quist 2005; Opsahl 2009; Lehtonen 2015). In this article, we document how these phrases are used in the speech of adolescents from a borough of West London and demonstrate the functional similarities between the current data and studies of adolescents in other West European contexts. Using a distributional analysis, we also draw several comparisons between our data and data collected in previous studies of adolescent speech in London. We find functional and distributional similarities and contrasts in both cases. We then discuss the consequences of these findings for the study of epistemic markers and their relevance in adolescent speech.

Recent accounts of discourse-pragmatic (DP) variation have demonstrated that these features can acquire social indexical meaning. However, in comparison to other linguistic variables, DP features remain underexplored and third-wave perspectives on the topic are limited. In this article, I analyse the distribution, function and social meaning of the ‘attention signals’ – those features which fulfil the explicit function of eliciting the attention of an individual – in just over 35 hours of self-recordings of 25 adolescents collected during a year-long sociolinguistic ethnography of an East London youth group. This leads me to identify an innovative attention signal – ey. Distributional analyses of this feature show that ey is associated with a particular Community of Practice, the self-defined and exclusively male ‘gully’. By examining the discourse junctures at which ey occurs, I argue that this attention signal is most frequently used by speakers to deploy a ‘dominant’ stance. For gully members, this feature is particularly useful as an interpersonal device, where it is used to manage ingroup/outgroup boundaries. Concluding, I link the use of ey and the gully identity to language, ethnicity and masculinity in East London.
