How to say "fence, hedge (field boundary)" in Arabic

Not a coincidence: Hebrew's own fence word, סְיָג — famous from the Mishnaic maxim עֲשׂוּ סְיָג לַתּוֹרָה, 'make a fence around the Torah' — and Arabic سياج both trace back to the very same Aramaic word, סְיָגָא. Modern Hebrew's everyday גדר took a different route; סייג survives for the specifically figurative, precautionary kind of fence.
