This project aims to combine typological and sociolinguistic approaches to language variation. Typological methods are applied to researching complexity of language structures but also to comparing sociolinguistic environments to one another. These innovations enable transforming rich sociolinguistic data to a typology of speech communities and to research if language structures adapt to the sociolinguistic environment in which they are and have been spoken. The project is directed by Associate Professor Kaius Sinnemäki.
