This paper argues that the conversational style of adolescents in multiethnic areas in Oslo is characterized by an extended degree of epistemic focus and expressions pointing explicitly towards the news value of utterances. The linguistic traits contributing to this notion is a set of discourse markers where wallah, or as it is often referred to in Norwegian; wolla (orig. Arab. ‘I swear by Allah’), seems to be prominent, together with Norwegian counterparts such as sverg, jeg sverger and helt ærlig (‘swear’, ‘I swear’ and ‘quite honestly’). Equipped with methodological insights from Interactional linguistics, the distribution and discourse functions of the markers are analysed in a corpus of conversations between adolescents growing up in multiethnic areas (the Upus/Oslo-corpus) and compared to another larger, representative corpus of modern Oslo dialect (the NoTa/Oslo-corpus). The discourse markers in question are also discussed in light of grammaticalization processes.
