Linguistic analysis C.E. and F.M. Voegelin, Classification and Index of the World’s Languages (New York: Elsevier, 1977), pp. 12–13; for Wolof: Cheikh Anta Diop, “Origin of the Ancient Egyptians,” in General History of Africa II, ed. G. Mokhtar (Paris: UNESCO, 1981), pp. 44–48. The consistent parallelism of grammatical paradigms is convincing in the case of Wolof. Attempts to link other African languages to pharaonic Egyptian that are selective in comparing forms are questionable, for instance, Théophile Obenga, “The genetic relationship between Egyptian (ancient Egyptian and Coptic) and modern Negro-African languages,” in The Peopling of Ancient Egypt: The General History of Africa, Studies and Documents, 1 (Paris: UNESCO, 1978), pp. 65–71, see discussion on pp. 100–101.
