Countable vs Uncountable nouns
Some nouns are not counted: no a/an in front and no -s at the end (water, weather, advice, information, luggage).
I drink water.
Look: I drink water. Nothing before water, and no s after it.
Forms
I have an apple.— an apple: apples can be counted, an means oneI have two apples.— with regular nouns such as apple, use -s for more than oneI drink water.— water is not counted: nothing in front, no s at the end
A common mistake
Wrong: We had a good weather.
Right: We had good weather.
So many people say a good weather, but weather is not a thing we count. We say: We had good weather.
More examples
Can you give me some advice?
Advice is the same: no a and no s, so Can you give me some advice?
My luggage is heavy.
Luggage is uncountable, so it takes is: My luggage is heavy. The same with The news is good.
