Through an interdisciplinary approach, the study demonstrates how social representations and linguistic practices influence the categorization of places, contributing to a form of spatio-sociolinguistic discrimination that shapes the perception and valuation of neighborhoods. By emphasizing the role of language in the structuring of social and territorial identities, this research enriches urban sociolinguistics and opens avenues for future research on issues of spatial categorization and linguistic inequalities in a globalized context.frLinguistic usageslanguage practicesurban spacemetalinguistic discourseshierarchizationsociolinguistic spacediscriminationterritorialityidentitycategorization.Thesis
