The dictionary has several aims; 1. To help advanced Yiddish students to better understand all kinds of texts and to use the idioms in their Yiddish conversation; 2. To serve as a lexicographic source for linguistics researching Yiddish and spoken Hebrew, and specialists in comparative phraseology; 3. To give the lovers of Yiddish a handbook that will help them find and recall the meaning of Yiddish idioms.
