Spanish as Immigrant Minority Language in Brussels: A Pilot Study on Maintenance and Vitality

Despite its demographic relevance, Spanish as an Immigrant Minority Language (IML) remains understudied in Europe. In Brussels, approximately 46,500 residents have Hispanic heritage, but their linguistic practices have largely remained unexplored in sociolinguistic research. This paper presents a pilot study on the language practices of the Hispanic communities in the city in order to assess language maintenance and vitality. Through an online survey among 125 adults with Hispanic heritage in Brussels, primarily first-generation immigrants, a highly multilingual sample was revealed, with most participants competent in at least four languages. While Spanish usage declines across generations, language competence remains high, with 60% of third-generation speakers still considering it one of their dominant languages. Findings challenge traditional minority–majority language maintenance perspectives, advocating for a multilingual approach to linguistic vitality. Patterns of language transmission, home language use, and integration highlight the communities’ adaptability while maintaining a connection to Spanish. Results point to unexplored sociolinguistic phenomena within the language minority, underscoring the need for further research on the Hispanic communities in Brussels.
