כַּרְעֵי תַּרְנְגֹלֶת (kar'ei tarnególet) — chicken legs; idiom for instability

Etymology

The image of something standing on chicken legs as an image of instability has a long and winding path from Babylonian dream interpretation to Slavic mythology, Yiddish adaptation, and finally Hebrew literary adoption. The original European source is the story in Daniel 2, where Nebuchadnezzar dreams of a great statue with a head of gold, chest and arms of silver, belly and thighs of bronze, legs of iron, and feet of iron mixed with clay. Daniel interprets this as a prophecy of successive empires. From this story emerged the Latin phrase pedes fictiles (feet of clay), meaning "fragile at the base." Its equivalents spread across European languages: "feet of clay" in English, pies de barro in Spanish, Colosse aux pieds d'argile in French, auf tönernen Füßen stehen in German.

When Yiddish speakers adapted the German expression, they replaced "feet of clay" with chicken feet: שטיין אויף הינערשע פֿיס (standing on chicken legs). The most plausible reason for this substitution is that Ashkenazi Jews in Eastern Europe were steeped in Slavic folk culture, where chicken legs already carried a powerful mythological resonance. In Slavic folklore, Baba Yaga — the archetypal forest witch who steals children — lives in a hut standing on chicken legs. The instability of such a foundation was vivid and familiar. (The image itself has a real-world basis: Siberian nomadic hunters did build forest shelters on tree stumps that resembled giant chicken feet.)

When late 19th-century Jewish writers from Eastern Europe shifted from writing in Yiddish to Hebrew, they translated the Yiddish phrase into Hebrew as עוֹמֵד עַל רַגְלֵי תַּרְנְגֹלֶת. The word תַּרְנְגֹל itself had entered Hebrew from Sumerian (tar lugal, "bird of the king") via Akkadian and Aramaic, first attested in Hebrew in the Temple Scroll found at Qumran. The phrase רַגְלֵי תַּרְנְגֹלֶת is attested in Hebrew from 1890 (Israel Haim Taviov, Ha-Melitz) and in Bialik's story "Arye Ba'al Guf" (1899).

The shift to the form with כַּרְעֵי rather than רַגְלֵי began in the 1920s and consolidated through the 1930s. The word כְּרַע appears in the Bible (e.g., Amos 3:12) and was used in Mishnaic Hebrew for the leg of a piece of furniture (כַּרְעֵי מִטָּה, כַּרְעֵי שֻׁלְחָן). Crucially, the Talmud (Berakhot 6a) already mentions "כַּרְעֵי תַּרְנְגֹלֶת" in the context of a passage advising that a person who wants to see demons should sprinkle ash around their bed and in the morning will find tracks shaped like chicken legs. Hebrew writers likely drew on this Talmudic source to lend the phrase an authoritative ring, and possibly also because the near-homophone קִרְעֵי (tatters) gave the expression a more viscerally precarious feel. By 1929 (Haaretz, 1932 (Davar on the Nazi party), 1935 (Jabotinsky), and 1938 (Alterman's first poetry collection), the כרעי form had clearly overtaken the רגלי form.
