פִלֵּחַ / הִתְפַּלֵּחַ (filleakh / hitpalleakh) — to slip through; to sneak in without permission

Etymology

The verbs פִלֵּחַ ("to slip something through") and הִתְפַּלֵּחַ ("to sneak into a place without permission") violate regular Hebrew morphology: both should have a dagesh (doubling dot) in the פ, and indeed a separate pair of verbs פִּלֵּחַ and הִתְפָּלֵּחַ exists with different meanings. The irregular pronunciation reflects a borrowed-word pattern — foreign words often preserve the phonology of their source language — yet no obvious foreign-language source with the right sound and meaning has been identified. The true origin is stranger than a simple loan.

The Babylonian Talmud (Avodah Zarah 39a) mentions a fish called צַלּוּפַח or צַלְבַח (variant manuscripts differ), described only as a non-kosher fish. Medieval commentators attempted to identify it: Nathan of Rome (the "Arukh") described it as a long snake-like fish that slips from the hand and is called "angila" (eel), while Rashi identified it with the Old French "angliia" (eel). Mendele Moykher Sforim, in Volume 3 of his natural history work "Toldot HaTeva" (1872), revived the Aramaic word as the Hebrew term for eel, inconsistently using both spellings צַלְבַח and צַלּוּפַח.

The writer Uri Nisan Gnessin, in his 1910 work "Beteram," exploited the eel's slipperiness as a metaphor: "she slipped from his hand like that צַלְבַח, which slips from the fisherman's grip." This vivid metaphorical use inspired Hebrew school students in the 1930s to coin a verb from the word. Amatzya Barles documented this in his 1937 article "Leshon HaYeladim" ("The Language of Children") in the journal Leshonenu: the verb לְהִצְטַפְלֵחַ (to slip away, evade) was in use, alongside לְצַפְלֵחַ meaning "to pass something quickly."

After this documentation, the verbs disappear from the record — but not because they fell out of use. It appears that over subsequent years of oral transmission among children, the connection to צַלּוּפַח was forgotten and the forms simplified: הִצְטַפְלֵחַ became הִתְפַּלֵּחַ, and צִפְלֵחַ became פִלֵּחַ (a consonant metathesis — ק/צ dropped, the remaining consonants reordered). The new forms appear from the 1940s onward. פִלֵּחַ appears in the 1947 Hebrew translation of Jabotinsky's "Hamishtan": "And where did Siryozha get that kind of money?" The meaning "sneak in without a ticket" for הִתְפַּלֵּחַ is well attested by 1968, when the Tel Aviv police charged a youth who "התפלח" into an ice-skating show without a ticket — the word appeared in the actual indictment, necessitating a parenthetical explanation in court.
