This article examines the literary representation of contemporary urban vernaculars (CUV) in fiction. It focuses specifically on four Swedish novels published in the last ten years, whose narratives are set in the urban and increasingly multilingual, migrant-rich and class-stratified peripheral areas of Stockholm, the capital of Sweden. The analysis centers on how they are situated in these urban peripheries, using written representations of spoken, non-standard Swedish CUV as symbolic resources to give authenticity to the narratives. We examine the distinctive linguistic features that are employed to evoke the imagination of CUV, and how these are used to build the fictional characters and to create certain recognizable social personas and practices. We also discuss the linguistic features that are available but are not exploited to represent the fictional characters’ ways of speaking, and possible reasons why this is so. Finally, we examine how the novels exploit contrasts between registers, particularly between CUV and adult second-language speaker styles and between CUV and standard Swedish, and with what effects. The findings are discussed in the context of the broader social discourses about language, migration, CUV and adult second-language speakers in present-day Sweden.
