This 1957 monumental volume is a cornerstone of Kartvelian linguistics, representing one of the most exhaustive studies of the morphological and syntactical structures of the Old Georgian language ever published. Authored by Ivane Imnaishvili, a distinguished scholar of the Tbilisi State University school, the work provides a deep dive into the internal logic of the medieval Georgian linguistic system, including the arrangement of nominal paradigms, the evolution of case endings, and the complex functional roles of cases within varied historical texts. Spanning nearly 800 pages, the study meticulously analyzes primary sources ranging from early hagiographic manuscripts to biblical translations and legal documents, tracing the development of the language's grammatical core during its formative centuries from the 5th to the 11th century.
