Other forms: potatoes
A potato is the brown vegetable that grows underground. Chips, mash, roast, and the bag in the bottom cupboard.
It is a tuber rather than a root, and it came to Europe from the Andes in the sixteenth century, going on to feed and then to starve whole countries. The plural takes an e, giving potatoes. English gets several phrases from it, including a hot potato for a subject nobody wants to handle and couch potato for somebody who does not get up. Sweet potato is a different plant entirely.
