An Overview of Countable Nouns and Their Uses

This short guide can give students an explanation of what countable nouns are in the English language. Although the primary focus here will be on nouns of this type, we will contrast countable and uncountable nouns in order to show how the two categories are different. This guide should be most useful for students who might be learning English as a second language, but it can also serve a purpose for any middle or high school students who are taking English classes. Teachers can incorporate some of this overview into their existing materials, and it might allow any students who need it to have a useful refresher on which kinds of nouns are countable, why English chooses to count them, and how we use them in sentence structures.

Why Do We Need To Know Which Nouns Are Countable?

Not all nouns are countable; we need to know the differences because they can affect the kinds of determiners or verbs we might use. You will recall that nouns identify people, places, or things. Any noun that we can use in conjunction with particular numbers is something that we can count. Therefore, countable nouns have both singular and plural forms. The determiners we need to use with these kinds of nouns must also match the forms we use in the sentence structure.

  • A or an are both common determiners that you would use with the singular form of a countable noun. You can say or write out; I see a cup on the table because both "cup" and "table" are countable nouns.
  • Further examples of this might include sentence structures like; I see three cups stacked on the table, or you could write I see four cups stacked on each of the three tables.

As you can see, sometimes the determiner does not need to change when you move a countable noun from its singular to its plural form.

Can We Omit the Article?

In English, articles are one of the writing mechanics that can help us identify countable nouns when we see them. While we would include them in many cases, keeping them out is sometimes necessary. For the most part, this sort of situation comes up when you are speaking or writing about nouns more generally.

  • You could say that the three dogs in the yard are brown. You are referring to and counting three specific dogs.
  • You might want to tell your friend that dogs don’t like to get wet.
  • Dog is still countable in English, but if you are referring to a trait of dogs in general, you would then omit the article.

Do Exceptions Exist for Countable Nouns?

Yes, you might encounter some exceptions for countable nouns in the English language. Often, this is something that will happen when you are dealing with nouns that English takes from other languages. This is because, in some cases, things you cannot count in English end up being things you can count in another language. Here is where the idea of countable and uncountable nouns can get a bit trickier for some students, particularly if you have ESL students who do have some nouns in their own language that we would not count in English. In such cases, the nouns that you would count in the other language need to follow the rules for the uncountable ones in English. Things that we would not count in English typically relate to abstract concepts, but this is not always true.

  • We do not count the word toast in English. If we want to get an idea of the amount of toast a person would like, we need to ask them how much toast they prefer. We cannot inquire about how many toasts they would like.
  • In some other languages, however, this is precisely the process that the mechanics would follow, and one might say that I prefer three toasts in the morning.
  • In English, we may be able to get around this problem by adding to the sentence. We can say; I prefer three pieces of toast in the morning. Now, we are using countable nouns to pluralize pieces and add that information to the amount of toast.


If you think in terms of the number of people, places, or objects you’re describing, you're beginning to understand which nouns you can count. They often have singular and plural forms, and they work well with the determiners we have in the English language. Be on the lookout for exceptions, and don’t forget that there are ways to make some uncountable nouns countable, too.
