Grammatica Celtica, by Johann Kaspar Zeuss, is a foundational work in the study of Celtic languages. Originally written in Latin, this comprehensive grammar explores the structure and history of the Celtic language family. Volume 1 delves into the phonology, morphology, and syntax of Old Irish, Welsh, and other Celtic dialects. Zeuss's meticulous scholarship and comparative approach laid the groundwork for modern Celtic studies. This edition offers invaluable insights into the historical development of these languages and their relationship to other Indo-European tongues. A crucial resource for linguists, historians, and anyone interested in the rich linguistic heritage of the Celtic peoples.
