הַנְדָּסָה (handassa) — engineering; geometry
Etymology
The word הַנְדָּסָה is ultimately of Persian origin, traveling through Arabic and medieval Hebrew translations before arriving in modern Hebrew with a substantially expanded meaning. In Middle Persian — the administrative language of the Sasanian Empire (226–651 CE) — the verb הַנְדָז meant "to measure." This verb entered the Babylonian Talmud (Bava Batra 89b), composed within the Sasanian Empire, and also appears in the writings of Asaph the Physician, a 6th-century Galilean medical author.
When Arab armies conquered the Middle East in the 7th century, the Persian verb was absorbed into Arabic as הַנְדַס. From it was derived the Arabic noun הַנְדַסַה, used to translate the Greek word geometria (literally "measuring the earth"). The word appeared in the Arabic-language writings of major medieval Jewish thinkers: in the Rikmah of Jonah ibn Janah (c. 1050), the Kuzari of Judah Halevi (1139), and the Guide for the Perplexed of Maimonides (1191).
In the 12th century, the Almohad movement persecuted Jews and Christians in Morocco and Muslim Spain, causing mass Jewish emigration. Among the refugees was Abraham ibn Tibbon, a physician who fled Granada for Lunel in Provence, where he began translating Arabic-language Jewish texts into Hebrew so that northern European Jews who could not read Arabic could access them. When he translated the Rikmah and the Kuzari, he encountered the Arabic term הַנְדַסַה and, finding no Hebrew equivalent, simply transcribed it as הַנְדָּסָה. His son Samuel used the same word in his Hebrew translation of Maimonides, and Samuel's son Moses used it when translating Euclid's Elements.
The ibn Tibbon translations circulated across Europe for centuries but the word הנדסה rarely appeared in use, since European Jews seldom studied geometry. A remarkable exception was David Gans, a German Jewish scholar who discovered the Hebrew Euclid translation in his uncle's house and fell in love with science, ultimately working at Tycho Brahe's observatory. In his book Nehmad ve-Naim he used מְהַנְדֵּס (a geometer), itself a transliteration of the Arabic muhandas. Haskalah writers subsequently adopted הנדסה for geometry. In the 19th century, Benjamin Ze'ev Halevi Sapir first applied מהנדס to the European engineers arriving in Palestine, and the word gradually displaced the competing loan אינג'ניר, a process completed by 1985.
