means A starchy tropical root vegetable (also called cassava or yuca) that's a staple food across Africa, Asia, and Latin America, but which contains cyanide-producing compounds in its raw form and must be properly processed—peeled, soaked, and cooked—before eating.

from English borrowed 'manioc' from French 'manioc', which came through Portuguese or Spanish from Tupi-Guarani languages of Brazil — likely from a word like 'mandi'oca', referring to the plant itself. European colonizers encountered the crop already cultivated by Indigenous peoples of South America, who had long known the techniques for detoxifying it, and the word traveled back across the Atlantic along with the plant.
