Nouns are words that name people, places, animals, things, or ideas. You may already know about types of nouns, singular nouns, and plural nouns. Now, you might wonder what countable and uncountable nouns are. Are they different from singular and plural nouns? Let’s explore this. Read the article to understand the meaning of countable and uncountable nouns, their definitions, how they are made, and how to use them in sentences with examples.

What Is a Countable Noun?

A countable noun identifies something you can count. These nouns appear in both singular and plural forms. To identify countable nouns, ask the question “How many?” For example, you count one apple, two apples, or one book, three books.

The Cambridge Dictionary defines a countable noun as “a noun that has both a singular and plural form and names something that can be counted.” The Macmillan Dictionary explains that countable nouns usually take a plural form and use a determiner in their singular form, such as “a,” “this,” “any,” or “a lot of.”

Here are some examples to understand better:

• Singular: a table, a cat, a chair.
• Plural: tables, cats, chairs.

Examples of Countable Nouns

Here is a list of some common countable nouns with their plural forms:

Singular	Plural	Singular	Plural
Car	Cars	Dog	Dogs
Pen	Pens	Chair	Chairs
Potato	Potatoes	Bottle	Bottles
Child	Children	Box	Boxes
Watch	Watches	Man	Men

Bird	Birds	Tree	Trees

2. She found three pencils in her drawer.
3. Sam bought a new pair of shoes yesterday.
4. The students are waiting for the teacher.
5. There are four chairs in the dining room.

Countable nouns are easy to identify because they can have both singular and plural forms.

What Is an Uncountable Noun?

An uncountable noun names something you cannot count directly. These nouns stay in a single form without a plural version and refer to substances, abstract ideas, or concepts. To identify uncountable nouns, ask the question “How much?” For example, you refer to milk, water, happiness, and sugar as uncountable nouns.

The Cambridge Dictionary defines an uncountable noun as “a noun that has one form with no plural and names something that cannot be counted.” The Macmillan Dictionary states that uncountable nouns often describe liquids, powders, or abstract ideas.
