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. 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.
