In the article, spatializations (discourses of ideal or stereotyped spaces) are conceptualized as powerful discourses of the surrounding society, providing resources for place‐bound identity construction in interaction. We combine a sociolinguistic analysis with Bakhtinian dialogism to understand how such “third” voices in dialogue empower and pluralize self‐ and other‐positionings embedded in the evocations of unofficial place names. Empirically, the focus is on toponyms that divide the socially mixed Vuosaari suburb in Helsinki into “older” and “newer” territories. The results show that when the stereotypes of “good” and “bad” neighbourhoods or other spatializations interpenetrate the uses of “Old” and “New Vuosaari,” they open room for the (re‐)voicing of the meanings of these toponyms for highly differentiated social ends. With the Bakhtinian framework bridging between socio‐spatial theory and sociolinguistics, the article develops a spatially sensitized approach to analyse the entanglements of the micro‐level contexts of interaction with the macro‐level discourses of meaning‐giving.
