Are potatoes and onions countable nouns?

Answer 1

Yes, the noun potato is a common noun, a word for any potato of any kind.

A proper noun is the name of a person, a place, a thing, or a title; for example:

• Delaney Alward, 2012 Little Miss Potato Blossom, Maine Potato Blossom Festival
• Potato Creek State Park, North Liberty, IN or Potato Mountain, Ouachita National Forest, Richland, AR
• Mr. and Mrs. Potato Head (toys)
• Sweet Potato Heaven (restaurant), Cullman, AL
• "Who Made the Potatoe Salad?", 2006 movie starring Daphne Bloomer
• "Potato People" (novel) by Angela Wright

Answer 2

The two nouns present in the question are both vegetables. Therefore when dealing with food, the noun varies if it is countable or uncountable.

This can only be proved by grammatically thinking of specific amounts of the object.

Potatoes:

1 potato, 2 potatoes, 5 potatoes

So potato is a countable noun.

Onions:

1 onion, 2 onions, 5 onions

So onion is a countable noun.

BUT:If we had to try lettuce:

Lettuce:

1 lettuce, 2 lettuce, 5 lettuce

One can immediately notice that the specific amount of lettuce does not make sense. Instead one can specify the amount by saying:

1 box of lettuce

2 bowls of lettuce

5 kg (kilograms) of lettuce

The reason for this is because the noun lettuce is an irregular plural. It remains the same in both the singular and plural form.

Answer 3

No, the plural noun 'potatoes' is a concrete noun, a word for physical objects.

Answer 4

It is a concrete noun
