The volume is a collection of contributions by colleagues from Europe and North America to celebrate the 75th jubilee of two outstanding scholars in the domain of Semito-Hamitic (Afro-Asiatic) comparative linguistics. They are Professor Aharon B. Dolgopolsky (Haifa) and Professor Herrmann Jungraithmayr (Frankfurt am Main), who have so much in common in their approach to a better reconstruction of Semito-Hamitic, based on their exceptional analysis. The papers reflect the academic interests of both these scholars (with particular emphasis on Cushitic and Chadic linguistics, respectively) and present the problems of this vast linguistic family in all its variety. These studies by well-known specialists of Semitic, Berber, Cushitic and Omotic as well as Chadic linguistics are both comparative and descriptive in nature and focus primarily on the lexicon.
