The Acta Academica Supplementum 2012 (2), under the outgoing editorship of Prof Dirk van den Berg, was launched on 16 September 2013. The author, Prof Peter Raper, is one of the leading place-name experts in South Africa. The Supplementum analyses the San origin of South African place names whereby different layers of language contact are exposed. For example, Dipodi (previously Jakkalsdraai), is an adaptation of the original San name. The first ‘di’ is the added Sotho preposition. ‘Po’ is equal to the San word ‘po’ (jackal) and the last ‘di’ equal to ‘/gi’ (to bend). Prof Raper’s research indicates that many place names carry evidence of various language shifts. By analysing these language layers, different phases of language contact are exposed. This research is instrumental in the preservation of a unique aspect of the South African cultural heritage.

Prof Raper is since 2011 Honorary Professor: Linguistics, in the Department of Language Management and Language Practice at the University of the Free State. He is one of South Africa’s leading toponymists. The fourth edition of the New Dictionary of Southern African Place Names, with Dr Lucie Möller and Prof Theodorus du Plessis as co-editors, is currently in the press. He is a member of the Commission for Toponymy of the International Geographical Union, as well as the Working Group for Toponymy of the International Cartographic Association, of which there are only ten members worldwide, and a member of the Editorial Advisory Board for the journal Names.
