Description by William F. Weigel


Yiddish has historically been the language of the Ashkenazim, the Jews of Central and Eastern Europe and their descendants around the world. At its peak, in the years immediately preceding the Holocaust, there were perhaps ten or eleven million Yiddish speakers worldwide, making Yiddish the most widely spoken Jewish language. As a combined result of genocide in Europe, cultural assimilation in America, and official and unofficial pressure to shift to Hebrew in Israel and Russian in the Soviet Union, today there are probably fewer than two million speakers, most of whom no longer use it as their primary language. With the rare exceptions of young Yiddish activists, it is only in certain Orthodox and Hasidic communities that Yiddish remains the language of everyday discourse and is still learned by children. However, there has been a resurgence of interest in Ashkenazic culture generally in recent decades, and Yiddish courses are now offered by many universities and Jewish cultural organizations.


The great Yiddish scholar Max Weinreich described it as a 'fusion language' that combines elements from Germanic, Slavic, Semitic, and other languages. This is certainly true, but most linguists would agree that at its core Yiddish is a West Germanic language, and thus a close cousin of English, and an even closer relative of German. A sample sentence that illustrates the mixture of components is the following: Der zeyde hot gebentsht khanike likht ('The grandfather blessed the Chanukkah candles'). The basic grammar is Germanic, as are the function words der and hot, the past tense markers ge-and -t, and the word likhtZeyde is Slavic, khanike is Semitic, and bentsh is from the Romance component. Sentences like this are quite common in Yiddish.

The name yidish in Yiddish means simply 'Jewish'. In the past, various designations for the language were used that emphasized the close connection of German and Yiddish, such as the scholarly 'Judeo-German' and the Yiddish taytsh (cf. Ger. Deutsch), which survives in the modern Yiddish verb fartaytshn 'to translate [into Yiddish]'. The language has also been referred to by the originally derogatory term zhargon 'jargon' or the somewhat more affectionate mame-loshn 'mother tongue'. (The latter term contrasts with loshn-koydesh 'language of sanctity, [i.e., Hebrew and Aramaic]'.)

History and Dialects

The early history of Yiddish is a topic of uncertainty and controversy.


It is fairly clear that the Jewish populations that first began speaking what could be called Yiddish came from various locales, such as France, Germany, the Slavic lands, and the Mediterranean. The difficult question is which of these groups contributed most to the distinctive character of the language and culture. The traditional view, which is also probably still held by the majority of scholars who have studied the question, is that Yiddish was born of eastward migrations. In other words, Jews from France (and perhaps Italy) moved into Germanic-speaking territories and adopted some form of Middle High German (the ancestor language of both Yiddish and German). More recently, several linguists have suggested that the most important migrations were of Slavic-speaking Jews who moved westward. This debate hinges in part on theoretical issues about the nature of language-contact influences.

Date of Birth

Dating the birth of Yiddish also presents special problems. Although there were Jews living in West Germanic-speaking areas in the first millennium C.E., this does not necessarily mean that their language was a lineal ancestor of Yiddish. In a similar vein, there is no clear-cut criterion for determining the point in time at which the Jewish and non-Jewish varieties of a Middle High German dialect had become sufficiently different to be considered separate languages. It is likely that the migrations that first gave rise to Yiddish occurred at some time between the Crusades and the Black Death (i.e., between the late 11th and mid 13th century). For present purposes, the somewhat arbitrary birth date of 1300 C.E. has been chosen.


The major dialect division is between Western and Eastern Yiddish. Western Yiddish was formerly spoken in Germany, Holland, France, Switzerland, and Hungary, but had largely become extinct through assimilation by the end of the nineteenth century. It is most obviously distinguished from the Eastern dialect by the absence of significant Slavic influence. Some scholars have argued that it should be considered a separate language. Eastern Yiddish has many regional variants, but the primary dialect divisions are Northeastern, Mideastern, and Southeastern. Sometimes these dialects are called 'Lithuanian', 'Polish', and 'Ukrainian', respectively, but such geographical designations correspond more closely to historical boundaries and should not be confused with the contemporary borders of these states. The Eastern dialects differ from one another substantially in vocabulary and grammar, but most conspicuously in the pronunciation of certain vowels, e.g:

Speakers who grew up in the United States often use a variety of the language that is a mixture, to some extent, of various Eastern Yiddish dialects. In popular parlance, there are two linguistic and cultural regions of Eastern Yiddish speakers, consisting of the "Litvaks" and the "Galitsianers."

Because it has never been the official language of a sovereign state, there is no official dialect of Yiddish. Since the end of the nineteenth century, however, a de facto literary dialect called 'Standard Yiddish' (yidishe klal-shprakh) has evolved and been adopted by many writers. It is based largely on the grammar of Southern Yiddish and the pronunciation of Northeastern Yiddish. It is the dialect usually taught today and used in most modern publications, even though it probably does not exactly correspond to anyone's native speech.

Contact with Other Languages

Yiddish and Hebrew

Hebrew (and to a lesser extent, Aramaic) words abound in Yiddish. These include not only religious and learned terms, but a large number of ordinary words as well. Most such Semitic borrowings are nouns, but there are also a significant number of adverbial words and phrases, such as bifrat 'in particular', beys 'while, during' and mistome 'probably'; and many formulaic expressions, such as olev hasholem 'peace [be] on him' (added after the name of a deceased person) and borekhabo 'welcome' [lit. 'blessed is the one who comes'] (used to greet guests). The prominence of the Hebrew/Aramaic component in Yiddish varies according to speaker/writer, audience, and genre. In scholarly or religious writing, Semitic loan words can comprise 25% or more of the lexicon. As an example, in the following sentence from Max Weinreich's Geshikhte fun der yidisher shprakh (vol. 1, p. 196), five of the twelve words include Hebrew material: "di ashkenazishe talmide-khakhomim hobn fun der tayne nit gekent nispoel vern" ('the Ashkenazic scholars could not be impressed by this claim').

There is a large class of Yiddish periphrastic verbs that consist of a Hebrew noun or participle (i.e., a form corresponding to the Modern Hebrew present tense) plus a form of a basic verb such as zayn 'to be' or hobn 'to have'. Examples include maskem zayn 'to agree', khasene hobn 'to marry', and nispoel vern 'to be impressed' from the sentence above.

Over the last century Yiddish has exerted noticeable influence on Israeli Hebrew. The sound system of Israeli Hebrew is based on Yiddish phonology, and the stress system and the realization of certain vowels and consonants are based on Sephardic Hebrew. Also, although resisted by language purists, many Yiddish words, loan translations, and grammatical constructions have found their way into colloquial Hebrew. For example, the Israeli greeting Ma nishma? (lit. 'What is heard?') is a calque or literal translation of the Yiddish Vos hert zikh?Some scholars have gone as far as to say that Israeli Hebrew is equally or more influenced by Yiddish than by ancient Hebrew.

Yiddish and the Slavic Languages

In most cases the coterritorial non-Jewish language with which Yiddish speakers came into contact was one of the Slavic tongues, such as Polish, Belorussian, or Ukrainian, and Yiddish/Slavic bilingualism among Jews was the rule rather than the exception. This contact resulted in widespread Slavic influences on Yiddish at every level. Some examples include:

  • A Slavic-type rule of anticipatory (regressive) voicing assimilation, as in fus benkl => fu[zb]enkl;

  • A system of verbal aspect highly influenced by the semantics of Slavic aspect, as in the prefix tse-;

  • A number of borrowed derivational morphemes, such as the agentive -nik (as in nudnik 'bore' from nudne 'boring') and the diminutives -tshik and -ke;

  • Numerous borrowed verbs, with an especially high proportion of verbs that distinguish manner of action, such as shushken 'whisper', kvitshen 'scream', and mlien 'simmer'. These borrowed Slavic verbs constitute a separate morphological class in Yiddish;

  • Numerous borrowed nouns, especially terms of a culturally or geographically specific nature (plant and animal names, foods, etc.). This part of the lexicon varies considerably by region;

  • Slavic kinship terms adopted for several major categories, e.g., zeyde 'grandfather', bobe 'grandmother', and plemenik 'nephew'.

Yiddish and English

Yiddish has had a quite noticeable influence on American English over the last century. The English of Yiddish-speaking immigrants and their children was of course heavily spiced with Yiddish words and phrases, many of which have worked there way into mainstream English. Some of these (e.g., bagel, shmooze, shtick, kosher, kvetch, etc.) remain identifiably 'Jewish' (either for phonological or semantic reasons), while many others (e.g., glitch, maven, mishmash, tush, klutz) have quietly merged with the rest of the English lexicon. A number of Yiddish idiomatic constructions have also entered colloquial English, such as the pattern I don't know from ___ (ikh veys nit fun ___), idioms (such as "From your mouth to God's ear"), and the dismissive shm-reduplication (Oedipus Shmoedipus: a boy shouldn't love his mother?). In addition, the English of many Orthodox Jews in America today maintains a number of Yiddish influences at all levels of the grammar.

Yiddish and German

Yiddish has sometimes been described as a dialect of German, probably because in many cases the Yiddish and German versions of a word are similar, if not almost identical, and because the two languages have a common ancestor in Middle High German. But other factors make it clear that Yiddish is a separate language:

  • In general, the two languages are not mutually comprehensible (this is especially true for German speakers trying to understand Yiddish);

  • A large part of Yiddish vocabulary (perhaps as much as 1/3) is not shared with German;

  • Much of the grammar of Yiddish differs substantially from that of German, having been acquired from contact with other (mostly Slavic) languages;

  • The two languages are geographically and culturally distinct.

In modern times some Yiddish speakers and writers have borrowed words freely from Modern German. Such use of Germanisms, called daytshmerish, was widely criticized by many stylists.

Selected Points of Grammar


Since its inception, Yiddish has been written in the Hebrew alphabet. In modern times the familiar 'Square Aramaic' version of the alphabet is nearly always used, but before the nineteenth century a version of the 'Rashi script' (the font typically used for Rashi's commentaries on the Bible) was more common. The exact spelling system used has also varied considerably with time and place, the main differences being in the representation of vowels and, in modern literature, the use of "superfluous" letters imitating German orthography. A standard spelling promulgated by the YIVO Institute for Jewish Research has only recently achieved general acceptance. (For example, the leading U.S. Yiddish weekly newspaper Forverts only fully adopted YIVO orthography in the 1990s.)

All modern Yiddish orthographies provide a fairly complete and consistent representation of the phonemes of the language. However, Hebrew and Aramaic loanwords (which are quite common) are spelled as they were in their language of origin (e.g., with most vowels omitted) rather than phonemically. This can create a problem for the language learner, since the pronunciation of these words is usually not predictable from their spelling. (This is true even for many Hebrew speakers: Yiddish and Israeli Hebrew pronunciations of the same word are often quite different.) Because of Soviet policies, Yiddish books that were published in the former Soviet Union represented Semitic words phonemically rather than with their original spelling.

Today Yiddish is still printed in Hebrew letters. One notable exception is Yiddish email, which is often rendered in Latin characters.

Sound Inventory

The phoneme inventory of Yiddish does not differ greatly from that of other West Germanic languages, but a few points are worth noting:

  • The voiceless stops (p, t, k) are relatively unaspirated (i.e., have a very short voice onset time), unlike English and German.

  • The coronal sounds (t, d, n) are dental rather than alveolar, probably as a result of contact with Slavic languages.

  • Like English, Yiddish lacks front rounded vowels (ü, ö). Hence sheyn 'beautiful' (cf. Ger. schön) and brider 'brothers' (cf. Ger. Brüder).

  • As with many European languages, there is considerable dialectal and individual variation in the pronunciation of the phoneme /r/. Articulation as a voiced uvular or velar fricative is probably most common, but an alveolar flap or trill is also often heard.


Stress. The incidence of stress varies. Stress in Germanic words usually falls on the first syllable of the word's root. Slavic and Semitic loanwords usually have penultimate stress. Unstressed vowels (especially those after the stressed vowel) are typically reduced (usually to something close to a lax e).

Phonotactics. As a result of language-contact influences, Yiddish allows a number of consonant clusters that do not occur in other West Germanic languages, for example dlonie 'palm (of hand)', mruk'grumbler' (Slavic borrowings); tkhum 'enclosure, pale', and gzeyre 'evil decree' (Hebrew borrowings).


Nominal Morphology

Gender. Nouns in Standard Yiddish (as well as most other dialects) are either masculine, feminine, or neuter. Gender is not usually predictable from the form of the noun, although there are some general patterns.

Number. The most common and productive plural suffixes are -s for nouns ending in a vowel, and -n for nouns ending in a consonant, but there are several others. Hebrew nouns usually retain their original plural forms in -im or -es (the latter derived from the historical Hebrew -oth feminine plural suffix). Plural forms of Germanic and Semitic nouns also often display changes in stem vowels: fus/fis 'foot/feet', kholem/khaloymes 'dream/dreams'.

Case. There are three nominal cases: nominative, accusative, and dative. The definite article, demonstratives, and (in some constructions) adjectives are fully inflected for case, but most nouns bear no case-marking. An oblique (accusative and dative) case suffix -n/-en is used only with proper nouns and kinship terms, and a few other nouns such as rebe/rebn 'Hasidic rabbi' and yid/yidn 'Jew'.


Possession can be marked in several ways. There is a morphological possessive marker -s that is attached to the dative form of the noun phrase and which works much like the English possessive -'s. The following possessive constructions use the nouns der zeyde '(the) grandfather' (masculine noun) and dos kind 'the child' (neuter noun):

  • dem kinds ketsl 'the child's kitten'

  • dem zeydns ketsl 'grandfather's kitten'

A highly unusual variation of the possessive combines it with the indefinite article (a/an, comparable to English) to form an indefinite possessive construction:

  • dem kinds a ketsl 'one of the child's kittens'

  • dem zeydns a ketsl 'one of grandfather's kittens'


Verbal Morphology

Yiddish verb stems are directly inflected for person and number only in the present tense:

  • ikh zing 'I sing'

  • du zingst 'you sing'

  • er, zi, es zingt 'he, she, it sings'

  • mir zingen 'we sing'

  • ir zingt 'you sing'

  • zey zingen 'they sing'

(Note that Yiddish has the distinction between familiar singular and formal singular or unmarked plural 'you' (du vs. ir) found in most European languages other than English.)

Unlike English and German, Yiddish has no preterite or simple past tense. The past tense is instead formed by the auxiliary 'to have' (or 'to be' for a few verbs) plus the past participle, e.g., Ikh hob gezungen 'I sang, I have sung'.


Word Order. The usual Yiddish sentence follows the Germanic 'verb-second' rule, viz., the inflected verb (or auxiliary) is the second constituent in the sentence, although the inflected verb or auxiliary appears first in certain constructions, such as yes/no questions and consequent clauses. Otherwise, word order is relatively free ('free' in the sense that order may be used to express discourse relations such as topic or contrast, rather than to code the meaning of the sentence.)


Before the 19th century, Hebrew rather than Yiddish was usually considered the proper medium for serious writing in the Ashkenazic world. Thus much of the Yiddish material that survives from that period was intended for women or men who lacked fluency in Hebrew. The flowering of modern Yiddish literature began in the mid-19th century and is most closely associated with the three founding figures of Mendele Moykher-Sforim (Sholem-Yankev Abramovich), Y. L. Peretz, and Sholem Aleichem (Sholem Rabinovich). Since that time, hundreds of thousands of Yiddish books have been published, including belles lettres, scientific and philosophical works, and translations of much of the European canon. Literary works of all genres were published in books and periodicals on five continents. Some of the stars of Yiddish literature include Avrom Goldfaden, Morris Rosenfeld, Avrom Reisen, Dovid Bergelson, Moyshe-Leyb Halpern, Yankev Glatshteyn, Itsik Manger, Chaim Grade, Avrom Sutzkever (currently residing in Israel), and Chava Rosenfarb (currently residing in Montreal). In 1978, the Yiddish writer Isaac Bashevis Singer won the Nobel Prize for Literature.
