Based upon Brugmann's Grundriss and the etymological dictionaries of Uhlenbeck (Sanskrit), Kluge (German), Feist (Gothic), Berneker (Slavic), Walde (Latin), and Boisacq (Greek). — Princeton: Princeton University Press, 1921. — xvii, — 307 p.
It has long been recognized that in both Balto-Slavic and Indo-European philology a serious handicap to comparative investigation lies in the fact that the etymological studies that have already been made are not generally available from the standpoint of Lithuanian, in its preservation of sounds and forms the most archaic of all living IndoEuropean tongues. The present work, which has grown out of an attempt on the part of the author to collect for his own use, both as student and teacher of the language, the most important of these references, will, it is hoped, serve as an immediate and practical key to the bulk of the etymological material offered by Lithuanian, and ultimately form the basis of a formal etymological dictionary.
