A Guide to Yiddish: The Mother Tongue of Ashkenaz

Walk through Williamsburg, Boro Park, Monsey, Kiryas Joel, Stamford Hill in London, or Bnei Brak in Eretz Yisroel, and you will hear it everywhere: on the bus, in the grocery, between a rebbe and his chossid, between a mother and her child. Yiddish â€” mame-loshn, the “mother tongue” â€” is the heartbeat language of Ashkenazic Jewry. For roughly a thousand years it carried the daily life, the humor, the heartbreak, the Torah, and the warmth of our people across Europe and beyond. It was nearly silenced in the Shoah, yet today it thrives as the living, breathing everyday speech of hundreds of thousands of chassidim. Whether you are marrying into a Yiddish-speaking family, moving to a heimishe neighborhood, learning the language of your grandparents, or simply proud of where you come from, this guide is a warm introduction to the mame-loshn and the world it holds.

History & Origins

Yiddish was born roughly a thousand years ago, when Jews from northern France and Italy settled along the German Rhineland and in towns such as Speyer, Worms, and Mainz â€” the cradle communities the Jewish world remembers by the acronym Shum. There, Jewish speech fused the Middle High German of their neighbors with the Hebrew and Aramaic (loshn-koydesh, “the holy tongue”) they had carried from the study hall and the siddur for generations. The result was a uniquely Jewish language: written in the Hebrew alef-beis, read right to left, German in much of its grammar and everyday vocabulary, but threaded through with the words of Torah and tefillah.

As Ashkenazic Jewry migrated eastward â€” into Poland, Lithuania, Ukraine, Hungary, and Russia over the centuries â€” Yiddish absorbed a rich layer of Slavic words and sounds from Polish, Ukrainian, and Russian. By the 1800s, Yiddish was the native language of millions of Jews across Eastern Europe, the medium of the shtetl, the marketplace, the cheder, and the chassidic court. It became the great unifier of Ashkenaz: a Jew from Vilna and a Jew from Galicia might pronounce things differently, but they understood one another.

The Dialects

Like any living language spread across a continent, Yiddish developed regional flavors. Three great Eastern dialects shaped the way it is spoken:

Litvish (Lithuanian, or Northeastern Yiddish) was spoken in Lithuania and Belarus â€” the world of the great Litvishe yeshivos and the misnagdic tradition. It is known for a crisp, precise pronunciation. Poylish and Galitzianer (Polish and Galician, the Mideastern and Southeastern dialects) were spoken across central Poland, Galicia, Ukraine, and Romania, the great heartland of chassidus. Hungarian (Ungarish) Yiddish, woven into the world of the Oberland and Unterland communities, carried its own distinctive vowels and rhythms. These differences live on vividly today: the vowel a Litvak pronounces one way, a Galitzianer or a Hungarian chossid pronounces another. Much of the Yiddish heard in chassidic neighborhoods today carries the warm Poylish and Hungarian coloring of the courts from which those communities descend.

The Golden Age of Literature & Theater

In the late 1800s and early 1900s, Yiddish blossomed into one of the world’s great modern literatures. Three writers are honored as its founding masters: Mendele Mocher Sforim (the “grandfather” of Yiddish literature), Sholem Aleichem (whose Tevye the Dairyman would one day become “Fiddler on the Roof”), and Y. L. Peretz. Yiddish newspapers, journals, poetry, and a vibrant Yiddish theater flourished from Warsaw to New York. In 1908, the Czernowitz Conference proclaimed Yiddish a national language of the Jewish people, and in 1925, YIVO, the Yiddish Scientific Institute, was founded in Vilna to study and preserve it. For a brief, brilliant moment, the mame-loshn was the everyday language of millions and the literary language of a flourishing civilization.

The Shoah & Its Devastation

That world was destroyed in the Shoah. The overwhelming majority of European Jewry murdered by the Nazis ym”sh were Yiddish speakers, and entire cities of Yiddish life â€” Warsaw, Vilna, Lodz, Lublin, and a thousand shtetlach â€” were wiped out. The great centers of Yiddish letters, the courts, the yeshivos, the theaters, the readers and the writers, were gone. A language that counted some eleven million speakers before the war was left bereft of its heartland. For many, Yiddish became the language of memory and mourning â€” the loshn of a vanished world.

A Living Language Today

And yet Yiddish did not die. The survivors who rebuilt â€” above all the chassidic rebbes who reestablished their courts in Williamsburg, Boro Park, Monsey, Kiryas Joel, and New Square, in Stamford Hill in London, in Antwerp, in Montreal, and in Bnei Brak and Yerushalayim â€” made a deliberate choice to raise their children in mame-loshn. In communities such as Satmar, Belz, Vizhnitz, Bobov, Skver, and many more, Yiddish is not a relic but the everyday language of the home, the street, the cheder, and the beis medrash. Children learn to read and daven in it; chosson and kallah build their homes in it; sefarim, newspapers, and magazines are published in it. Far from a museum piece, Yiddish is today one of the fastest-growing languages among young families in the frum world â€” passed l’dor vador, from generation to generation, as vibrantly as ever.

A Few Words & Phrases

You will pick up Yiddish quickly by living among it, but here are a few words and phrases to warm the welcome. A greeting: Gut morgn (good morning) and A gutn (have a good one); on Shabbos, Gut Shabbos, and on Yom Tov, Gut Yontif. When something is good and right, it is gut or fein; a warm, homey person or place is heimish â€” the very word at the heart of HeimishMart. A grandmother is a bobe and a grandfather a zeide; the children are kinderlach. Mazel tov needs no translation, and nu? can mean “so?”, “well?”, or “go on” depending entirely on the eyebrows. Be’ezras Hashem (with G-d’s help) and im yirtzeh Hashem (G-d willing) thread through everyday speech, as does baruch Hashem (thank G-d) in answer to “how are you?” A clever, charming person has chein; a heartfelt effort comes fun hartzn (from the heart). And when something is simply wonderful, you may hear the highest praise of all: a mechaye â€” a true delight.

That, in the end, is what the mame-loshn is â€” a delight, and a homecoming. It is the language in which our great-grandparents whispered Krias Shema over sleeping children, in which the badchan made a wedding laugh and cry at once, and in which a whole people kept faith through exile. To learn even a little of it is to be folded into something old, warm, and very much alive. As we like to say around here: we’re in this together â€” mir zenen ale tzuzamen.
