# Shibboleth
**Shibboleth** (Hebrew שִׁבֹּלֶת, *šibbōlet*) is a Hebrew word meaning both "ear of grain" and "flow, stream, torrent" that became the archetype of a pronunciation test used to identify members of an outside group, after the Gileadites used it at the fords of the Jordan to detect fleeing Ephraimites in Judges 12:1–6[1](https://jewishstudies.rutgers.edu/images/documents/faculty/Rendsburg/ehll-shibboleth.pdf). In English it has come to mean any word, custom, or doctrine that distinguishes one group from another, or an outmoded slogan still adhered to by a party[2](https://www.etymonline.com/word/shibboleth).
| Key fact | Detail |
|---|---|
| Hebrew meaning | "Ear of grain" (15 occurrences in the Bible) and "flow, stream, torrent" (4 occurrences)[1](https://jewishstudies.rutgers.edu/images/documents/faculty/Rendsburg/ehll-shibboleth.pdf) |
| Biblical episode | Gileadites under Jephthah held the Jordan fords and required fugitives to say the word; Ephraimites pronounced it "sibboleth" and were killed[3](https://www.jewishencyclopedia.com/articles/13573-shibboleth) |
| Reported death toll | "Forty and two thousand," which Hastings' Dictionary calls an obviously exaggerated account[4](https://www.studylight.org/dictionaries/eng/hdb/s/shibboleth.html) |
| Entry into English | Late 14th century in Bible translations; figurative sense "watchword or test-word of a party" by the 1630s[2](https://www.etymonline.com/word/shibboleth) |
| Modern sense shift | By 1862 the word had evolved to mean an outmoded slogan still adhered to[2](https://www.etymonline.com/word/shibboleth) |
| Linguistic significance | The paired forms šibbōlet and sibbōlet in Judges 12:6 are prime evidence for regional dialects in ancient Hebrew[1](https://jewishstudies.rutgers.edu/images/documents/faculty/Rendsburg/ehll-shibboleth.pdf) |
## The biblical episode
The narrative in Judges 12:1–6 follows a battle between Jephthah's Gileadites and the tribe of Ephraim, which had been angered at being left out of Jephthah's campaign against the Ammonites[5](https://www.biblegateway.com/resources/encyclopedia-of-the-bible/Shibboleth). After defeating the Ephraimites, the Gileadites took possession of the fords of the Jordan to cut off their retreat[3](https://www.jewishencyclopedia.com/articles/13573-shibboleth).
When a fugitive asked to cross, he was asked whether he was an Ephraimite. If he answered no, he was put to a test: "Say 'Shibboleth.'" An Ephraimite, whose dialect lacked the "sh" sound, pronounced the word "sibboleth" and was killed on the spot[3](https://www.jewishencyclopedia.com/articles/13573-shibboleth). The [Encyclopedia](https://www.edgepedia.org/encyclopedia) of the Bible notes that the significant point of the story is not the meaning of the word but its pronunciation, which is why English versions transliterate rather than translate it[5](https://www.biblegateway.com/resources/encyclopedia-of-the-bible/Shibboleth).
## The word's two meanings
In the [Hebrew Bible](https://www.edgepedia.org/hebrew-bible), *šibbōlet* means "ear of grain" in passages such as Genesis 41:5–7 and Ruth 2:2, and "flowing stream" or "flood" in passages such as Psalm 69; it can also mean "branch" (Zechariah 4:12)[3](https://www.jewishencyclopedia.com/articles/13573-shibboleth) • [5](https://www.biblegateway.com/resources/encyclopedia-of-the-bible/Shibboleth). Which sense the Gileadites intended is uncertain. Modern commentators have decided the word was probably used in the "river" sense, in reference to the Jordan[2](https://www.etymonline.com/word/shibboleth), and the 1911 [Encyclopædia Britannica](https://www.edgepedia.org/encyclop-dia-britannica) likewise judges the second sense likely, the Jordan being a river[6](https://en.wikisource.org/wiki/1911_Encyclop%C3%A6dia_Britannica/Shibboleth).
The medieval commentator Ḳimḥi supposed that other words beginning with "sh" were actually used at the fords, with "shibboleth" recorded only as a typical instance[3](https://www.jewishencyclopedia.com/articles/13573-shibboleth). The Radak commentary on Judges 12:5 makes the same point: the fugitives were tested with every word containing a shin, and the text chose one of them[7](https://www.sefaria.org/Radak_on_Judges.12.5).
## Linguistic evidence
Because שִׁבֹּלֶת (*šibbōlet*) and סִבֹּלֶת (*sibbōlet*) appear together in one verse, the passage stands as key proof that ancient Hebrew had regional dialects, at least in pronunciation, specifically one separating the Ephraimites from the Gileadites, though scholars disagree about the particulars.[1](https://jewishstudies.rutgers.edu/images/documents/faculty/Rendsburg/ehll-shibboleth.pdf) The Jewish Encyclopedia adds that the rarity of similar dialect examples in biblical literature is attributed to Judaic editors, though instances of letter interchange do exist, such as shin for tsade in Amos 7:9[3](https://www.jewishencyclopedia.com/articles/13573-shibboleth).
## History of the English word
The word entered English in the late 14th century through [Bible translations](https://www.edgepedia.org/bible-translations)[2](https://www.etymonline.com/word/shibboleth). Its figurative sense, "watchword or test-word or pet phrase of a party, sect, school, etc.", appeared by the 1630s, and by 1862 it had evolved to mean an outmoded slogan still adhered to[2](https://www.etymonline.com/word/shibboleth). [Noah Webster](https://www.edgepedia.org/noah-webster)'s 1828 dictionary already recorded both senses: the biblical criterion and, hence, "the criterion of a party... usually some peculiarity in things of little importance"[8](https://1828.mshaffer.com/d/word/shibboleth). Current dictionaries list two main senses: an old idea or phrase no longer accepted by many people as important or appropriate to modern life, and a custom or word that distinguishes one group of people from another[9](https://www.oxfordlearnersdictionaries.com/us/definition/english/shibboleth).
## Shibboleths beyond the Bible
Pronunciation tests of this kind recur across history. During the [Sicilian Vespers](https://www.edgepedia.org/sicilian-vespers) of 1282, Italians used the word *cicera*, "chick pease", to identify French, who could not pronounce it correctly[2](https://www.etymonline.com/word/shibboleth); the 1911 Britannica gives the word as *ciceri*[6](https://en.wikisource.org/wiki/1911_Encyclop%C3%A6dia_Britannica/Shibboleth). In the current conflict, differences between Ukrainian and [Russian phonology](https://www.edgepedia.org/russian-phonology) have enabled [Ukrainians](https://www.edgepedia.org/ukrainians) to identify Russian soldiers[10](https://pmc.ncbi.nlm.nih.gov/articles/PMC10389733/).
World War II examples show the principle applied deliberately. US Marine training on Pavuvu and [Guadalcanal](https://www.edgepedia.org/guadalcanal) used a "sign and countersign" procedure in which challengers asked for the name of an automobile containing an "L", so that an American dialect would be exposed by the reply; a Japanese speaker rendering "Cadillac" or "Chrysler" as "Cadiwac" or "Chryswer" would give himself away[2](https://www.etymonline.com/word/shibboleth). When such markers are secret and intended only for insiders to recognize each other, they are called furtive shibboleths[11](https://www.youtube.com/watch?v=Qi-GBuZxazs).
## Modern study and uses
Researchers in phonetics use "shibboleths" to mean well-documented pronunciation features that detect a speaker's origin, a usage that extends the biblical term to second-language accent research[12](https://pmc.ncbi.nlm.nih.gov/articles/PMC12106924/). An agent-based model of signaling mimicry takes the story as its starting point while noting its probably apocryphal and exaggerated nature, and observes that people do treat others preferentially based on pronunciation even when only two phonetic variables are compared[10](https://pmc.ncbi.nlm.nih.gov/articles/PMC10389733/). Pronunciation assessment scholars trace the practice back to Judges and note that shibboleth-style identity tests are endemic in situations of inter-group conflict as a means of establishing insider and outsider status; a modern institutional descendant is Language Analysis for the Determination of the regional or social Origin of asylum seekers (LADO), in which decisions about the legitimacy of an asylum-seeker's claims are made based on analyses of his or her speech productions[13](https://discovery.ucl.ac.uk/10047821/1/Isaacs%2520LAQ%2520Final.pdf).
The word has also given its name to unrelated things. In computing, Shibboleth is an identity-provider software product, a superset of [SAML 2.0](https://www.edgepedia.org/saml-2-0), used for single sign-on authentication in systems such as Canvas[14](https://community.instructure.com/en/kb/articles/387389-configuring-shibboleth-and-canvas-authentication). In literature, "Schibboleth" is a 1955 poem by [Paul Celan](https://www.edgepedia.org/paul-celan), and [Jacques Derrida](https://www.edgepedia.org/jacques-derrida)'s 1986 study of Celan is titled *Schibboleth: pour Paul Celan*[15](https://www.dictionnaire-academie.fr/article/A9S0770).
