This study uses the Dialect in British Fiction 1800–1836 database to chart the changing representation of the language of the labouring poor during the early nineteenth century. It finds that, broadly speaking, while the voices of the labouring poor are sometimes represented in novels at the start of the period, most novels evince little interest in either the linguistic nuances of these characters’ speech, or the access to their lives and thoughts that this speech provides. Around the middle of the period, there is a rapid increase in the fictional representation of the voices of the labouring poor specifically in novels set in rural Scotland and Ireland and – at least in some novels – this is connected to a greater interest in the lives and perspectives of these characters. By the end of the period, while there is a broadening out into extraterritorial varieties and a continuing interest in the voices of the rural labouring poor of Scotland and Ireland, these developments have not translated in any substantial way to an interest in either the rural labouring poor of England or Wales, or the urban labouring poor of any nation or region. Overall, the study demonstrates how fiction can be used to provide an insight into changing attitudes towards speakers and language varieties.
