Yiddish

The word for "yes" in Yiddish is "יאָ (yo)."

no problem = kein problem

נישטאָ פֿאַרוואָס- nishto farvos

"Good luck" in Yiddish is spelled as "הצלחה". It is transliterated as "Hatzlacha".

"meh-SHU-gah", originally a Hebrew word, is used in Yiddish as an adjective to mean 'crazy', but in the colloquial sense, certainly not as a formal medical diagnosis. A couple of examples: -- If your friend suggests a plan with which you totally disagree, you might express your disbelief by asking him "What are you ? Meshuga ? ! That'll never work." -- If you are overwhelmed by all the little things you have to take care of today, you might heave a big sigh and exclaim "Oy ! This paperwork is making me meshuga !"

It means a person who never got it together in his life, a sap for whom things never seemed to work out. Closely related to a "schlimazel" ... a person beset at every turn with bad luck. In the Seinfeld ensemble, George Constanza was one part schlemiel and one part schlimazel. Surprisingly, the word is a biblical name. See B'midbar (Numbers) 1:6. "Shelumiel, the son of Zurishaddai" was a top man in the tribe of Simeon during the 40-year trek through the desert. The Torah doesn't recount any details of his personal story, but the Midrash describes a string of sad experiences that befell him, and his name became a symbol for unproductive life, in Jewish folklore.

To speak with a Yiddish accent, you can focus on pronouncing certain sounds differently, like emphasizing the "ch" sound (more like clearing your throat), adding a bit of a "d" sound after words ending in "t" or "s," and drawing out vowel sounds. Listening to native Yiddish speakers can also help you mimic the accent more accurately.

Three answers: 1). Why not ? ! 2). In order to facilitate interpersonal communication, much as any other of the world's hundreds of distinct languages is used. 3). Yiddish is a patois, that is, a blend of the languages of all the countries in which European Jews have been dispersed during the past thousand years. The single language that it resembles most is probably Renaissance German, but it includes plenty of Russian, Polish, Slavic, Hebrew, and lately, English, among others. It is currently re-emerging somewhat as a living, spoken language in every-day use, after decades of decline due in large part to the eradication of the majority of the world's Yiddish-speaking population in the Holocaust. To ask why Yiddish is spoken is to ask why anyone speaks the language of his ancestors as far back as he has any knowledge of his roots. See also: Spanish in the USA. Ladino.
