Segregation and linguistic urbanization : the defined urban otherness or " the foreigner is a person ".

Urban sociolinguistics, which is dedicated to the study of production and of discursive organisation of social spaces has to conceive segregation under its two polarised components : a necessary state of intra-urban relations and a permanent process of construction of various territorial levels of the urban space. The article analyzes the inherent tension between the state (to subscribe to the relationnal system of the urban community members perceived as given, as stable) and the process (to be the authority on speech which produces, modifies in interaction the representations of space, the reports/ratios to the places, the dialects), in other words, to be in a logic of founded sociolinguistic individuation and melting the territorialisation.

From this point of view, two types of speech must be distinguished : those arising specifically from segregation which aim at setting up distinct borders, territories, subspaces and those depending from discrimination which engage (relying on the space perceived as stable) the social polarization of spaces, the selective specialization of the places which returns to the segregated groups.

Relying on a theorization of linguistic urbanization which affirms the value and the function primacy of mobility in the urban culture for the production of social space, the current research (whose methodology and results are presented in details in this article) aims to collect the descriptive categories produced by the actors of a given space (Rouen space / France) and to analyze discursively the linguistic attitudes produced in such a context. In other words, the object of the field work engaged on the rouennais site is to confront the known urban segregative practices with the denominations of the populations known and self referred as foreign.
