The »Dictionary of Yiddish Loan-Words in German Dialects« documents contact between the German and Yiddish languages, with special reference to German dialects. The material was taken from German dialect dictionaries, compiled systematically and revised lexicographically and etymologically. The introductory chapters of the dictionary deal with aspects of historical and linguistic integration, the state of research on the subject, the sources drawn upon, and Hebrew and Aramaic etymologies.
