What are Countable Nouns?

Countable nouns are things we can count. They have a singular form and a plural form.

You can use numbers with them.

• one book, two books
• one chair, three chairs
• one student, many students

We use specific words to talk about the quantity of countable nouns:

• a / an (for one item): a pen, an apple
• Numbers: two pencils, five friends
• many: How many books do you have?
• a few: I have a few questions.
• some (for positive sentences): I have some friends.
• any (for questions and negative sentences): Do you have any questions?, I don’t have any pens.

With countable nouns, we use the verb are （または were in the past) for plural forms.

What are Uncountable Nouns?

Uncountable nouns are things we cannot count individually. They usually do not have a plural form.

These nouns often refer to:

• Liquids: water, milk, coffee
• Materials: wood, paper, gold
• Abstract ideas: information, advice, love
• Food items (often in bulk): rice, sugar, bread

We use specific words to talk about the quantity of uncountable nouns:

• much: How much water do you need?
• a little: I need a little sugar.
• some (for positive sentences): I have some money.
• any (for questions and negative sentences): Do you have any information?, I don't have any advice.

With uncountable nouns, we always use the verb is （または was in the past).

How to Ask About Quantity: 'How many?' vs. 'How much?'
