The aim of this article is to present the findings of an analytical framework we have designed to monitor discriminatory political discourse on immigration. Through the understanding of how some of the most relevant studies in three disciplines (political science, social psychology and linguistics) have framed racism, we try to infer how such racism may manifest in discourse through particular discriminatory tendencies. The combination of these tendencies has contributed to the designing of the proposed analytical framework that aims, by means of 12 standards, to systematically certify political discourse as discriminatory, quantify how much discriminatory discourse is and assess how such discrimination is legitimised or justified. By implementing such a framework within the context of Catalonia, this pilot study offers a global picture of how Catalan political discourse on immigration is constructed and how each of the standards appears (or does not appear) in discourse. Once the viability of this framework is proven, we conclude it could be the basis of comparative research in other contexts.
