By folk etymology from Arawak aru-aru [meal of meals (because it was used to draw poison from arrow wounds)]
源自 阿拉瓦克語 aru-aru的民間詞源 [餐中餐（因為可以用來從箭傷處將毒吸出）]

<注釋>The arrowroot is just one of many plants that the European settlers and explorers discovered in the New World.The Arawak, a people who formerly lived on the Caribbean Islands and continue to inhabit certain regions of Guiana, named this plantaru-aru, meaning .meal of meals,. so called because they thought very highly of the starchy, nutritious meal made from the arrowroot.The plant also had medicinal value because its tubers could be used to draw poison from wounds inflicted by poison arrows.The medicinal application of the roots provided the impetus for English speakers to remakearu-aru into arrowroot, first recorded in English in '9'. Folk etymology—the process by which an unfamiliar element in a word is changed to resemble a more familiar word,often one that is semantically associated with the word being refashioned—has triumphed once again,thus denying us the direct borrowing ofaru-aru and giving us arrowroot instead.
竹芋僅是歐洲探險家和拓荒者在新大陸發現的多種植物中的一種。曾居住在加勒比海各島，現仍在蓋亞那部分地區居住的阿拉瓦克人把這種植物稱為aru-aru 意思是.餐中餐.， 這樣稱呼是因為他們非常看重這種用竹芋粉做成的澱粉狀的，非常有營養的食物。這種植物同時還有醫療價值，因為其塊莖可用來從毒箭箭傷處把毒吸出來。這種植物的醫療作用促使講英文的人重新將aru-aru 命名為 arrowroot ，'9'年首次在英文中予以記載。 詞的通俗變化就是比較陌生的詞被比較熟悉的詞所替代的過程，常常是被一個語義上與被翻新的詞有聯繫的詞。這裡，通俗辭彙學又一次取得勝利，不允許我們直接借用aru-aru ，而是另給了我們一個 arrowroot 。
