Usage

Plural word for potato The plural form of potato is potatoes. The plurals of several other singular words that end in -o are also formed this way, including tomato/tomatoes and echo/echoes. In some cases, the plurals of words that end in -o that are adopted from another language can be formed by adding either -es or -s, as in mosquito/mosquitoes/mosquitos or mango/mangoes/mangos. However, this is not the case with potato/potatoes. Potatos is an invalid spelling of the plural of potato.

Etymology

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."
