Strand 3 : Typology and Dynamics of Linguistic Systems

Updated: May 4, 2022

Manager : Katharina Haude (Sedyl – Inalco), co-responsable: Dmitry Idiatov (Llacan – Inalco

Strand 3 studies the diversity of the world's languages. Most of its members are field linguists with strong expertise in the description and documentation of less studied languages. Research in this area focuses on typology (i.e., the study of universals and differences found in world languages regardless of their genealogical relationship), as well as variation in space and time between geographically or genealogically related languages. These include in-depth interlinguistic analyses of particular linguistic phenomena, as well as studies of the short- and long-term effects of contact between related and unrelated languages.

Many Strand 3 projects build on the results of the first phase of LABEX-EFL, for example by using the databases created there. This empirical base will be complemented by the creation of new databases designed for quantitative and qualitative analysis, benefiting from expertise in more than 100 languages and language families.

The originality of Strand 3 lies in the interaction between the history of linguistics, historical linguistics (reconstruction of macro-families, long-term typological change), contact linguistics, linguistic documentation and typology. Research is based on qualitative and quantitative approaches (intensive use of databases and electronic corpora to evaluate theoretical problems). The increasing interoperability between all these resources and the cross-checking of hypotheses between the different approaches will provide innovative scientific perspectives.
