Departing from the existing literature which explores individual attitudes towards the European Union, this paper aims to analyse the role of language, more specifically of the capacity to speak more than one language, in shaping feelings of individual self-perceived role in European politics. Political efficacy constitutes an important indicator to understand how civil society engages in political, social and economic dynamics, and it proves especially important in a supranational complex environment such as the European Union. Whereas the literature traditionally focuses in macro-level country conditions and micro-level socioeconomic explanations to political efficacy, the linguistic factor remains surprisingly underlooked. This work hypothesises that multilingual individuals feel more politically efficacious compared with their monolingual counterparts, arguing that language functions as a participatory structure prompting more opportunities in the realm of the European Union as seen through the lens of Political Opportunity Structure theory. The research is carried out by analysing the data contained in the recent Eurobarometer SP540: Europeans and their languages published in May 2024 through a logistic regression model. The results provided by the model are statistically relevant and confirm the envisaged hypothesis.This study constitutes a solid foundation to consider language as a relevant factor to explain feelings of political efficacy in the European Union, which has enormous implications in policies relating to the fields of language promotion and education.
