Philadelphia: Yale University; Linguistic society of America University of Pennsylvania, 1939. — 351 p. — (William Dwight Whitney Linguistic Series)....The publication of the book has been made possible by a grant of Yale University through the Committee on Research in Language and Literature.
The writer of this note considers Prokosch's treatment of the strong verb a masterpiece. It is probably his greatest contribution to our understanding of the history of the Germanic languages.
The book will be welcomed by all scholars in Germanics, especially by the large number of younger scholars in this country who received their training from Prokosch or came under the influence of his magnetic personality in some other way. They will find here a comprehensive and consistent account of the phonology and the morphology of the Germanic languages by a great scholar with strong well-considered personal views. To some the book will doubtless prove a challenge. If its publication should lead to a vigorous discussion of moot questions, all who knew Prokosch would be gratified, knowing as they do that he was ever hospitable to the ideas of other scholars and enjoyed nothing more than a clear-headed vigorous discussion of such problems.
