"This edition is intended primarily for the reader whose knowledge of late medieval Latin and sixteenth-century German is too small to permit him to work with Luther in the original languages...We have tried throughout to translate Luther as he thought translating should be done. That is, we have striven for faithfulness on the basis of the best lexicographical materials available." - General Editor's Preface.
