caneh, can-, cann- +
(Hebrew: kaneh, reed; Latin: canna, reed, pipe)
Long ago, tall, slender, and hollow reeds grew on the banks of the Jordan and Nile Rivers
The word for "reed" in the Hebrew, Arabic, and Egyptian languages was kaneh. This word passed over into Greek and Latin, and into the languages of western Europe where a remarkable word family grew from the root canna.
Some words are easy to trace back to canna; such as "sugar cane", a "walking cane", and even a "cannon" are all clearly related to the reed in shape. With just a little imagination, the words "canal" and "channel" can also be associated with a pipe or groove.
It is difficult to see how the word "canon", or law, can be derived from the root meaning reed. Since reeds were long and straight, they were often used as measuring rods; and so, the word "reed" came to mean "a standard"; ultimately, it became "an authoritative standard", or law.
