This book presents a uniform description of the entire Georgian verbal system by taking into account its historical development and contemporary features of every type of conjugation pattern. Part one explains the evolutionary path of the verb from Proto-/Old Georgian to the modern language. Then based on the outcome of this, i.e., its current features, it then proposes that diathesis--the morphosyntactic alignment of a verb and its arguments--is a much better criterion than voice (used in previous analyses) to arrange Georgian verbs into a coherent classification system. Part two then uses diathesis to organize Georgian verbs by paradigmatic realizations. This book contains an extensive glossary, tables, and an index of every known Georgian verb stem, arranged by classification and alphabetically by root. The table of contents is set up to allow the reader to quickly find sections based on a verb's conjugation class.
