Translingual Africa

About the Project

Project term: April, 2021–March, 2024

  This project aims to establish a new perspective on the multilingual nature of Sub-Saharan Africa by focusing on linguistic features uniquely observed on the African continent. We explore not only well-studied typological subjects but also unique linguistic phenomena arising in African multilingual environments that have tended to be ignored in the literature. This project also aims for a better understanding of African languages and translingual ecology by expanding the scope of traditional research on African linguistics by strengthening scholarly networks of African linguistics in Japan.
