From June 28 until August 13, 2022, Guy Kouarata is doing again linguistic BantuFirst fieldwork on lesser known varieties of the Teke group (Bantu, B70), both in Congo-Kinshasa and Congo-Brazzaville. Just like during his 2021 fieldwork campaign, he will collect new data to feed several ongoing historical-comparative linguistic investigations aiming at a better understanding of their classification within West-Coastal Bantu.
