This talk explores the naming practices of the Hadzabe people. Based on data from the field, the presentator discusses the origins of some family and personal names of the Hadza people and the reasons for the adoption of foreign names from neighbouring communities over indigenous Hadzabe names. Note: This talk has not gone through a process of peer review, and findings should therefore be treated as preliminary and subject to change. Acknowledgement and citation: Lusekelo, Amani. 2020.
