This article, relying on Bakhtin's approach to canonization, demonstrates an empirical link between language and ideology. The authors employ content and discourse analysis to examine political discourse exemplified in editorial writing as a particular speech genre. They scrutinize editorials in four newspapers published in Catalonia, two of them in Castilian and two in Catalan. Despite political differences between the papers in each language, the authors discern a Catalan-language discourse style that differs significantly from the Caslilian-language discourse style. They conclude that the historically canonized discourse styles, different in Catalonia's Castilian and Catalan press, reflect the intimate relationship between language of use and ideology.
