Why Is There Confusion over the Plural of Potato?

There is confusion because the rule for forming plurals with nouns ending in "o" isn't straightforward. Most nouns will just add an "s." For example:
  • "Kangaroo" becomes "kangaroos."
  • "Piano" becomes "pianos."
Some add es. For example:
  • "Echo" becomes "echoes."
  • "Torpedo" becomes "torpedoes."
With some words, both versions are accepted. For example:
  • "Volcano" becomes "volcanoes" or "volcanos."
  • "Halo" becomes "haloes" or "halos."
The plural of "potato" is always "potatoes." Unfortunately, there is no clever way of knowing which nouns ending "o" follow which rules. You have to know. (For example, you have to know that "potato" becomes "potatoes," but "piano" becomes "pianos.")

Beware

Don't Use an Apostrophe to Form a Plural

Adding 's is never an option when forming the plural of a noun. Despite this simple rule, inexperienced writers often feel compelled to add an apostrophe, especially when the noun ends with a vowel (e.g., piano, tomato, emu). For example:
  • Mango's are low in calories. wrong cross
  • Mangoes are low in calories. correct tick
