This is the key to exercises to Beginner's Lithuanian by Antanas Klimas, Leonardas Dambriunas and William R. Schmalstieg, which has been in print since its initial publication in the early 1960's, . Beginner's Lithuanian was originally published as Introduction to Modern Lithuanian. It is not just a grammar, but a monument to the Lithuanian language, which in its modern form is more archaic than the most ancient writings we have of any Indo-European language. This book is a key to exercises. It contains the answers to all of the questions and problems posed in Beginner's Lithuanian (and also of course to those in Introduction to Modern Lithuanian). It is perfect for the student who is teaching himself Lithuanian. The Key to Exercises has long been out of print. We are happy to make it available again. Note: The Key to Exercises is a companion volume to Beginner's Lithuanian and Introduction to Modern Lithuanian.
