Yiddish is a combination of the local languages of Germany, Poland, Russia, and other Eastern European nations where Jews settled from the Middle Ages to the Twentieth Century. It's a complete language full of dramatic expression that reached its height of development before World War II. Many of these words and expressions are still uttered daily by those who don't know their origins. You'll find that many of these words are very onomatopoetic.
