來(lái)源：
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(yǔ) aru-aru的民間詞源 [餐中餐（因?yàn)榭梢杂脕?lái)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(xiǎn)家和拓荒者在新大陸發(fā)現(xiàn)的多種植物中的一種。曾居住在加勒比海各島，現(xiàn)仍在圭亞那部分地區(qū)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?yàn)樗麄兎浅？粗剡@種用竹芋粉做成的淀粉狀的，非常有營(yíng)養(yǎng)的食物。這種植物同時(shí)還有醫(yī)療價(jià)值，因?yàn)槠鋲K莖可用來(lái)從毒箭箭傷處把毒吸出來(lái)。這種植物的醫(yī)療作用促使講英語(yǔ)的人重新將aru-aru 命名為 arrowroot ，'9'年首次在英語(yǔ)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(guò)程，常常是被一個(gè)語(yǔ)義上與被翻新的詞有聯(lián)系的詞。這里，通俗詞匯學(xué)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(gè) arrowroot 。
