Countable or uncountable Nouns

Countable nouns are things we can count. They have a singular (one) and a plural (more than one) form. We can use indefinite article a/an with singular countable nouns.

• I have an apple.
• There are three houses.
• She bought four books.

Uncountable nouns (or mass nouns) are things we do not usually count as separate items. They don't usually have a plural form and are treated as singular.

• I need some water.
• We have a lot of rice.
• The weather is nice today.

We often use 'some' and 'any' with both countable and uncountable nouns. Use 'some' in positive sentences and 'any' in negative sentences and most questions.

• I have some eggs.
• We don't have any pens.
• Do you have any sugar?

We use different words to talk about a large quantity. Use 'many' for things you can count and 'much' for things you cannot count.

• There are many students in the class.
• We don't have much time.
• How many books do you have?

We use 'a few' and 'a little' to talk about a small quantity (not a lot, but enough). Use 'a few' with countable nouns and 'a little' with uncountable nouns.

• I have a few friends nearby.
• She put a little sugar in her tea.
• We have a few questions.

Sometimes, we can talk about a specific quantity of an uncountable noun by using a container, piece, or unit.

• He ate a bowl of rice.
• I would like two glasses of water.
• She ate three pieces of cake.
