Potatoes or Potatos — What Is Correct and Why?
The correct plural spelling of the word potato is potatoes, with an “e” added before the “s”.

This happens because of a simple English pluralization rule:
words ending in -o preceded by a consonant take -es, not just -s.
Why Is Potatoes the Correct Spelling?
The Rule
Nouns ending in a consonant + “o” add -es to become plural:
Examples:

| Tomato | Tomatoes |
| Potato | Potatoes |
| Hero | Heroes |
This rule applies in US, UK, Canadian, and Australian English.
