cane n.
late 14c., "long slender woody stem," from Old French cane "reed, cane, spear" (13c., Modern French canne), from Latin canna "reed, cane," from Greek kanna, perhaps from Babylonian-Assyrian qanu "tube, reed" (compare Hebrew qaneh, Arabic qanah "reed"), which may come from Sumerian-Akkadian gin "reed."
