How to Form
Countable vs Uncountable Nouns
| Countable Nouns | Uncountable Nouns |
|---|---|
| Can be counted: one, two, three... | Cannot be counted with numbers |
| Have a plural form: book/books | No plural form: water (not |
| Can use "a" or "an": a pen, an egg | Cannot use "a" or "an" alone: |
| Examples: apple, ball, cup, pencil | Examples: water, rice, milk, bread |
Measuring Words for Uncountable Nouns
When you want to count uncountable nouns, use a measuring word:
| Measuring Word | Uncountable Noun | Full Phrase |
|---|---|---|
| a glass of | water | a glass of water |
| a bottle of | milk | a bottle of milk |
| a bowl of | rice | a bowl of rice |
| a slice of | bread | a slice of bread |
| a piece of | paper | a piece of paper |
| a cup of | tea | a cup of tea |
Remember: The measuring word (glass, bottle, bowl) is what you count. "Two glasses of water" -- you count the glasses, not the water!
Key Rules
- Countable nouns can have "a", "an", or a number in front of them. "I ate an orange. I ate two oranges."
- Uncountable nouns cannot have "a", "an", or a number directly in front of them. Say "some rice", not
a rice. - Use "some" with both types. "I have some books." "I need some water."
- Use "many" only with countable nouns. "There are many pencils." (not
many water)
Common Mistakes
| Wrong | Right | Why |
|---|---|---|
| I drink a milk. | I drink some milk. | "Milk" is uncountable, so do not use "a" |
| She has many water. | She has a lot of water. | "Water" is uncountable, use "a lot of" not "many" |
| Give me two breads. | Give me two slices of bread. | "Bread" is uncountable, use a measuring word |
| I want a rice. | I want some rice. | "Rice" is uncountable, use "some" not "a" |
