Origin & History of “rhubarb”
The Greeks had two words for ‘rhubarb’: rhḗon, which was borrowed from Persian rēwend, and which evolved into Latin rheum, now the plant’s scientific name; and rha, which is said to have come from Rha, an ancient name of the river Volga, in allusion to the fact that rhubarb was once grown on its banks (rhubarb is native to China, and was once imported to Europe via Russia). In medieval Latin rhubarb became known as rha barbarum ‘barbarian rhubarb, foreign rhubarb’, again with reference to the plant’s exotic origins; and in due course association with Latin rheum altered this to rheubarbarum. It passed into English via vulgar Latin *rheubarbum and Old French reubarbe.
