The definitive analysis of Indo-European in its time, Hirt's grammar (19211937) is a monument of the German philological tradition.The distinguished German philologist Hermann Hirt (18651936) wrote this seven-volume grammar soon after the discovery of Tocharian and the decipherment of Hittite. Volume 1 (1927) introduces the Indo-European language family, considers etymology and semantic shift, and provides a detailed analysis of the Indo-European consonant system.The distinguished German philologist Hermann Hirt (18651936) wrote this seven-volume grammar soon after the discovery of Tocharian and the decipherment of Hittite.

Born around the time when Bopp and Schleicher were publishing their ground-breaking work on Indo-European, and a young man when Brugmann published his monumental comparative grammar (all available in this series), Hirt began this seven-volume grammar in the 1920s soon after the exciting discovery of Tocharian and the decipherment of Hittite. The project arose out of his extensive research on the historical phonology of Indo-European vowels, which led him to consider much wider issues. Volume 1 (1927) introduces the Indo-European language family, its origins and subgroups, discusses etymology, roots and semantic shift, and analyses the Indo-European consonant system.Einleitung; 1.
