Social relationships and shifting languages in Northern Thailand1

This paper explores how speakers’ understandings of the conduct of social relationships mediate changing and socially distinctive syncretic language practices in a Northern Thai community. Although a shift away from vernacular (Kam Muang) speech styles to Standard Thai was emblematically tied to young and urban speakers in nostalgic discourses, syncretic speech styles and metalinguistic discourses also reflected local and socially positioned understandings of institutional roles and social relationships. I argue that scholars of language change and shift should foreground the mediating role of social relationships in speakers’ uses and understandings of their communicative repertoires across multiple timescales.
