Catalan and Estonian can be considered "medium-sized" languages with some key common features that allow us to analyze the evolution of the two cases comparatively. Firstly, other formerly hegemonic languages (Spanish and Russian, respectively) have historically minoritized them. Secondly, the political equilibrium has now changed in such a way that the "medium-sized" languages have been resituated in the public sphere, regaining some institutional recognition. In turn, this has caused the formerly dominating languages to be resituated too, where a high degree of contact between the two linguistic communities exists. Finally, in the globalization era, ideologies about (minoritized) languages may shift from identity-based values toward more pragmatic and instrumental ones. This article presents ethnographically collected data from both Tallinn and Barcelona (2008-2009), providing a reading of the Catalan case and evolution as seen through the Estonian experience. The study examines language-ideological constructs underlying the discourses of the linguistic groups in contact, how they affect and are affected by the context, how they interact with and co-modify each other and ultimately, how can they affect the process by which a "medium-sized" language may be adopted by "new speakers" and acquires a stable position at the level of its public functions.
