This paper examines the interactive effects of motives and contextual constraints predicting linguistic convergence with Finnish speakers among a small group of Swedish-speaking Finns. The data were collected among university students in Helsinki (N = 82). A moderated mediation analysis demonstrated the primacy of speakers' competence motive for linguistic convergence to Finnish. However, this relationship was moderated by interlocutors' competence in Swedish (i.e. interlocutor language constraint): speakers' competence motive was a weaker predictor of convergence to Finnish when their interlocutors' competence was low. The theoretical implications of these findings for accommodation in bilingual contexts are discussed.
