Understanding what has happened
with the ablaut
A chapter from linguistics
This article first examines the status of ablaut in comparative Indo-European linguistics, especially in Franz Bopp (Vocalismus, oder sprachvergleichende Kritiken), Jakob Grimm, Karl Brugmann, Ferdinand de Saussure (Mémoire sur le système primitif des voyelles dans les langues indo-européennes) and Jan Baudouin de Courtenay (Versuch einer Theorie phonetischer Alternationen). The existence of affixation in this language family led to the denial of a morphology based on ablaut until 1870s. It is then shown that following the redefinition of the relationship between phonology and morphology in SPE, analyses of Afro-Asiatic languages (especially Jean Lowenstamm’s apophonic path) shed new light on the matter.
