Polygenesis, Convergence, and Entropy:

An Alternative Model of Linguistic Evolution Applied to Semitic Linguistics.

In this study, the author challenges the traditional monogenetic "family tree" model (including wave-theoretical emendations) as an appropriate representation for genetic relationship within language families. As a viable alternative, he proposes a polygenetic model which applies the notions of "convergence" and "entropy" to linguistic evolution. A section discussing specific problems in Afro-Asiatic at large is followed by an analogous section dealing with specific problems in Semitic. One major portion of the discussion revolves around a number of longstanding problems in connection with phoneme inventories and sound change in Semitic. This is supplemented by analogous deliberations on morphology and the syntax of complex noun phrases. Special attention is paid to the issue of "bi-radicalism" vs. "tri-radicalism" Another focus of the discussion is on the issue of diglossia or polyglossia in Arabic in the light of the proposed theory, and on selected current issues in the history of Arabic linguistics. 207 Seiten mit 92 Tab., broschiert (Harrassowitz Verlag 1998)
