During the 10th World Congress of African Linguistics (June 7-12, 2021), organized online by Leiden University, Lorenzo Maselli, Sara Pacchiarotti and Koen Bostoen presented two papers with original language data collected in the West-Coastal Bantu homeland: one titled “Phonetic and laboratory phonological research on hunter-gatherer substrate interference in the West-Coastal Bantu homeland region: Some preliminary results” and one titled “On the origin of verb-final subject indexes in Ngwi (West-Coastal Bantu, DRC)“. Recordings of both talks are available on the conference platform.
