נוּרָה (nura) — light bulb
Etymology
Throughout the nineteenth century, as new lighting technologies transformed daily life — safety lamps, gas lighting, and eventually electric light — Hebrew writers covering these innovations reached for the ancient word מְנוֹרָה (menorah). This made sense: the word, from the Semitic root נ.ו.ר ("light/fire"), was familiar to every Jew as the name for the Hanukkah lamp and the seven-branched Temple candelabrum. By mid-century, every illuminating device was called a מְנוֹרָה, regardless of type or technology.
The root נ.ו.ר runs across Semitic languages: Arabic نور (nur, "light"), Arabic نار (nar, "fire"), Akkadian nūru ("light"), Aramaic נוּרָא ("fire"), and Hebrew נֵר (candle) all share it. The word מְנוֹרָה itself was thus a natural choice — and was used for Humphrey Davy's safety lamp, gas lanterns, and ultimately Edison's incandescent bulb after 1879.
But in that same period competing terms also entered use. Chaim Zelig Slonimsky, editor of Ha-Tzefira, preferred עֲשָׁשִׁית — a Talmudic word for a portable lamp with a glass shield (Berakhot 25b), whose meaning he based on Rashi's French gloss lanterna. The word survived in modern Hebrew for a lamp or lantern. Other writers preferred פָּנָס (also from Talmudic Aramaic, ultimately from Greek phanos, "torch/lantern"), which came to mean streetlight, headlight, and flashlight. A fourth term, נִבְרֶשֶׁת (Aramaic, from Daniel 5:5 and the Talmudic story of Queen Helena's golden lamp-stand), was eventually restricted by the twentieth century to a decorative ceiling chandelier (שַׁנְדְלִירָה).
The abstract noun תְּאוּרָה ("illumination") was coined by Ben-Yehuda in July 1891, derived from the root אור on the pattern of תְּשׁוּבָה.
The specific word נוּרָה for "electric light bulb" appears for the first time in a Ha'aretz news item in September 1944, describing a shortage of bulbs and their black-market sale. The word, built directly on the root נ.ו.ר, used the feminine nominal pattern נוּרָה and filled the semantic gap left by the overextension of מְנוֹרָה. It quickly became the standard Israeli term.
