The present volume unifies various studies issuing from the author's
etymological research over the past decade and concentrating on the
elaboration of regular consonantal correspondences between Semitic,
Egyptian, Berber, South Cushitic, and West Chadic languages. The
historical comparative analysis of the South Cushitic and West Chadic
sibilants, pharyngeals, and laryngeals is complemented by chapters on
new etymological evidence for the affricate origin of certain
Proto-Semitic sibilants, a critical appraisal of Rossler's theory on
Egypto-Semitic comparative phonology, the external correspondences of
Ahaggar h and Ghadames b, the Berber reflexes of Afro-Asiatic
glottalized sibilants, and the background of compensatory vowel
lengthening in Proto-East Cushitic.
