Dialect contacts in contexts of migration. The case of the Equatoguinean immigrants in Madrid, Spain

Sociolinguistic study about the immigrants from Equatorial Guinea in the Autonomous Community of Madrid, Spain. Primary research methodology: semi-directed interviews composed of life story interviews; linguistic questionnaires.

Summary: Despite the fact that Equatorial Guinea is the only Spanish-speaking country in the Sub-Saharan Africa — and constitutes, therefore, a singular case in the Spanish-speaking world —, it has very little visibility in studies about the Spanish language. In a similar way, the Equatoguinean immigrants have never been subject of any research on language and migration. This project aims to study the sociolinguistic situation of the Equatoguineans in Madrid, especially the importance of languages and language / variety contacts during the integration process, as well as the immigrants’ attitudes towards the involved languages and dialects.



Since 1999 the language of eastern Sephardim (Judenspanisch, Ladino, Judesmo, Spaniolisch) builds an important issue of investigation in Iberoroman Linguistics at the University of Basel.

Our interest is focused primarily on the investigation and documentation of the modern Judeo-Spanish language and mainly on the way it had been applied orally and in written form by the descendants of the Jews expulsed in 1492 from the Iberian Peninsula. We are essentially studying sephardic communities in the former Ottoman Empire in the second half of the 19th century.
