Etymology: The name "cocoyam" is a compound of "coco" and "yam," but the story behind it is a chain of mistaken resemblances. The original cocoyam was grown in the shade of coconut groves, and its tubers looked enough like true yams that growers borrowed the yam half of the name. Later, a different plant was introduced that resembled that older crop, so it inherited the same label. The name therefore describes a likeness, not a relationship: the plants are not closely related to yams at all. The word's first element, "coco," points to the coconut palm that shaded the original crop, while "yam" carries the lesser sense of a starchy tuber. Each newer arrival was named for the one before it, so the word records a sequence of resemblances rather than any single botanical fact.

Synonyms: taro, yam, root vegetable, edible tuber
