My Dad was raised in the Bronx by his Lithuanian parents to whom Yiddish was their primary language. But like so many 1st generation Americans, the focus was on assimilation and speaking English. Dad mostly spoke Yiddish with his sister (my Mom was a 2nd generation American and spoke very little Yiddish). Still, there was a bissel of Yiddish in our home and as happens, it was often used to say things they didn't want the kids to understand. One of my Dad's sayings was "Zolst vaksen vi a tsiba'le, mit kop in d'rerd!" He meant it as "you are driving me nuts", but it means "you should grow like an onion, with your head in the ground!" Like so much in Yiddish, it is very emotionally expressive, but loses something in the translation.
The term machetunim refers to in-laws. But an Auntie of mine, who was a very funny lady, used to refer to the Machetunim and the Machetooties. One being the male side and the other the female side of the family. It was not until I was in my 30's, and taking a Yiddish language class at the JCC, that I learned she had made up Machetooties. It sounded so like a Yiddish word I never thought to question it! Vey is mir! which is similar to “Woe is me!” and like Oy vey! but a lot worse. In Yiddish, it can always get worse!
With its mixture of German with Hebrew, Aramaic, Slavic, and even some Romance Languages, it is written in Hebrew, but thankfully it can be found in English transliteration. No kvetching or kvelling, here is a list of 20 common Yiddish words that everyone should know:
