The online Yiddish Cultural Dictionary, known in Yiddish as ווילנער ווערטערבוך (Vilner Verterbukh) was initiated in January 2018 in Vilnius, Lithuania (first facebook announcement). YCD invites colleagues, students and more general readers to send in words that are missing and of course to let us know about errors of any kind (at the email: info@yiddishculturaldictionary.org). By the summer of 2026, YCD approached 53,000 main entries, and contained more than 1.1 million words of text and 1,750 notes (all in Yiddish) on usage, stylistics, nuance, etymology, social history and the lively debates of today's Yiddish world. To search the notes, please key in to the search box הערה (for notes) and אזהרה (for cautions).

Seeking to complement rather than duplicate, YCD is rooted in descriptivism and variationism rather than normativism and purism, and in traditionalism and search for the Yiddish spirit of things, rather than in reform, radicalism and replacement. It seeks to bridge the frighteningly wide divide between Hasidic (/Haredi) Yiddish (and the remnants of bona fide secular Yiddish) with that of a slew of occasionally syrupy primers, printed or online, which implicitly delegitimize much actual Yiddish usage. The goal here is to make a modest contribution toward the reunification of Yiddish in the deeper twenty-first century. YCD implicitly contends that the spirit of the language of the great literary masters of the twentieth century, and of the last generation of pre-Holocaust born speakers, lives on in the inclusive spirit of middle-of-the-road Yiddish stylistics which acknowledges the wings of religious and secular, traditional and radical, and standardist vs. dialect-oriented.

Note that "reunification" here does not imply an attempt to make literary standard Yiddish and the emerging new Hasidic standard Yiddish identical. That would be neither possible nor desirable. It is however an attempt to revert to the mainstream version of literary standard Yiddish that is empirically both much more of a broad tent and much closer to Hasidic Yiddish than the ultranormativist, purist, ausbauist version which is driving toward there being two Yiddishes, a real one and an experiment whose academic success is inversely related to (and dependent on) the disappearance of native speech communities in its midst. Put differently, the aim of recognizing different dialects and varieties within a language is at variance with the aim of moving an ausbauist experiment ever further in the direction of language separation. YCD aims to record thousands of items by which, broadly speaking, religious and secular Yiddish may continue to enrich each other, as they have been doing for close to two centuries.

The original wordpress edition at YiddishCultural.Dictionary.org continues at present alongside the new mobile-friendly, rapid-search YiddishCulturalDictionary.com. Note that some details, and entire entries (occasionally even groups of entries) are missed by the transfer mechanisms, and are found only in the wordpress original at .org. Please let us know about such issues arising, and the problem will be promptly addressed. The numbers at the bottom of each page of the .com mobile-friendly version are double the number of entries picked up from .org at the time (for now the counter still counts entry name and entry text separately, this will be addressed in due course, alongside some other issues waiting solution).

YCD is in principle permanently free (and without log-in) online, and constructed to enable users to browse up and down the page at will as in a traditional print dictionary, in the spirit of finding related items, not to mention Yiddish pearls you were not even looking for. Again, please don't hesitate to drop us an email informing of errors. In the case of typos it's enough to just copy and paste the typo into the email, we'll take it from there.

Please consider making a contribution toward YCD's survival and growth. If you require tax-deductible status in the United States, please write (info@yiddishculturaldictionary.org).
