Origin of potato
First recorded in 1545–55; from Spanish patata “potato,” variant of batata “sweet potato,” from Taíno
Explanation
The potato is a mighty tuber! You can find it baked, mashed, or fried, among other things, in kitchens the world over. Potato, which comes from the Spanish word patata, originally meant "sweet potato." Potatoes have been around for quite awhile. If you'd lived in the Andes 1800 years ago, you might have been eating potatoes ever since (though you might be sick of them by now). Remember that the plural form of this starchy vegetable ends in "toes."
