שִׁבֹּלֶת (shibbolet) — ear of grain; shibboleth

Etymology

The Hebrew word shibbolet has two distinct senses in the Bible: the more common meaning is "ear of grain" (a head of wheat or barley), while a rarer sense — found in Psalms 69:3 — refers to a flowing stream of water. Both senses appear in Biblical Hebrew, though the precise Semitic etymology is uncertain and comparative evidence for the "flowing water" sense is limited.

The word became internationally famous through a single episode in the Book of Judges (12:6), in which warriors of Gilead used it as a linguistic password to identify Ephraimite fugitives trying to cross the Jordan River. The Ephraimites, according to the text, could not produce the initial consonant correctly and said sibbolet instead — whereupon they were killed. This story gave rise to the use of shibboleth in English, Dutch, and many other languages as a technical term for any linguistic or cultural marker that distinguishes one group from another; Dutch resistance fighters in World War II used the place name Scheveningen as a shibboleth to expose German infiltrators who could not produce the Dutch sch- sound.

Modern linguists are skeptical of the traditional interpretation — that the Ephraimites merged shin with samekh — because no other West Semitic language is known to have that feature, and evidence from Samaritan ostraca (8th century BCE, near Ephraim's territory) and later Samaritan Hebrew shows no such merger. The most widely accepted scholarly alternative holds that the Gileadites actually pronounced the word with an interdental fricative (thibbolet, like the th in English thing), a sound preserved in Arabic but merged with shin in Hebrew proper. Ephraimites, lacking this sound, would have substituted samekh.

The column author proposes a novel hypothesis: the password word was שִׂבֹּלֶת — with a left-hand sin rather than right-hand shin — referring to the rarer "flowing water" meaning. If the merger of left-hand sin with samekh was an early feature of Ephraimite speech (a merger that eventually spread to most Hebrew dialects, though not to the Samaritans), then the story makes linguistic sense: an Ephraimite asked to say sibbbblet (with left-hand sin) would produce sibbolet (with samekh), which is exactly what the text says.
