צֹמֶת (tsomet) — intersection, junction

Etymology

The word צֹמֶת first appears in the Mishnah tractate Hullin, in a discussion of the laws of kosher slaughter. The Mishnah rules that an animal whose legs have been severed "from the knee and below" is kosher, but one severed "from the knee and above" is not — and then adds: "so too if the tsomet ha-gidin (צומת הגידין) is removed" (4:6). The talmudic sages debated what exactly this term meant, and the definitions offered by Rashi and by Abraham ben David of Posquières directly contradict each other. What is clear from the phrase is that a tsomet ha-gidin is a point where tendons converge in the knee area — the word coming from the root צ.מ.ת, which in rabbinic Hebrew means "to gather, collect, converge." The Midrash Bereshit Rabbah uses the same root: "your fathers were mitzamtim" — that is, accumulating, gathering wealth (83:4).

For centuries the word צֹמֶת existed in Hebrew only as part of this one halakhic compound phrase. The transformation began in February 1897, when a writer in HaTzfira needed a Hebrew equivalent for what we would call a "nerve center" or "transportation hub": "This city is a mother city in Israel, a tsomet-gidin of railroads and a great steam-ship port on the Sazh River." Nahum Sokolov, the editor of HaTzfira, adopted this extended usage. Then in August 1905, Sokolov took the decisive step of liberating the word to stand on its own: "the trams gather together, and then, from the point of tsomet of the paths, they fan out in different directions." Sokolov typeset the word with spaced letters — the method he and Eliezer Ben-Yehuda used to signal a linguistic novelty to their readers.

Over the following decades, צֹמֶת spread from HaTzfira to other newspapers and into spoken Hebrew. One complication was grammatical gender. Sokolov used the word as feminine (as the examples above suggest), and many speakers follow this usage to this day, saying for example tsomet merumezeret ("signaled intersection"). But when lexicographers finally registered the word in dictionaries, they assigned it masculine gender based on its one Mishnaic use: "ניטל צומת הגידין" — where nital (taken), not nitla, establishes masculine. From the 1930s onward, masculine usage also appears in print, and both genders remain in circulation.

The second half of the 20th century brought a new word into competition with צֹמֶת. As the Ayalon Highway project developed in the 1960s — the first true highway interchange in Israel — engineers working with the Canadian planning firm needed a Hebrew word for "interchange." By February 1968, the term מַחְלֵף had been coined for this purpose. The word derived from the root ח.ל.ף (to replace, to change) in the maktel instrument pattern (like mavreig "screwdriver," masheir "transmitter"). As Israeli highways were built, major intersections became interchanges, and מחלף entered common speech, with צומת increasingly reserved for grade-level intersections. Named interchanges like Geha and Mesubim preserve place-name histories of their own.
