The purpose of this thesis is to investigate how language functions in urban space within the framework of globalization, emphasizing the connections between language and social and physical space in urban areas. It places emphasis on exploring the complex relationship between language, the physical configuration of urban spaces, and the social dynamics that unfold within these settings. By focusing on the international migrant community spaces located in Rosengård, Malmö, and the Chungking Mansions in Hong Kong, the research process employs a comparative methodological framework and grounds in globalization theory, linguistic theory, and human geography. It provides an in-depth analysis of how language shapes urban spaces and reflects the distinctive characteristics of specific urban environments. The thesis argues that linguistic landscapes and language practices within migrant community spaces exert a territorialization effect on both urban and social spaces, which may have a co-effect with the stigmatization of these immigrant neighborhoods.
