The two prefix-conjugations in East Cushitic, East Semitic, and Chadic

It has long been observed by Cushiticists that the prefix conjugation in various Semitic languages represents one of the major arguments for treating this language group as belonging to the Semitohamitic (Erythraic, Afroasiatic) language phylum. From Semitic and Berber we are acquainted with (at least) two different prefix conjugations, a short one and a long one. THe long from is found in Berber and in several Semitic languages, although there is no general agreement about this. With this in mind, we should be surprised if we could not find so-called long imperfect forms in Cushitic as well. A strong candidate would be the Beja present which nasalizes the second radical, which is lengthened in other languages. In this context, however, I should like, not to discuss the problem bearing on the verbal forms of North Cushitic, but rather to draw the attention of the compartive Semitohamiticist to some East Cushitic languages for which new material is now available. ITt seems convenient to limit this discussion to the Rendille and Boni languages which have recently become knownthrough the work of Bernd Heine (1975–76, 1977, 1978, 1980, 1982) and Hans-Jürgen Sasse (1979, 1980a, 1980b).
