We were taught at school that if we want to make something plural, we should add "s" at the end. Later on, I learned that there are uncountable nouns. Not so much familiar with it. Can you please give some examples?
Uncountable nouns are substances, concepts etc that we cannot divide into separate elements. We cannot count them.
Lets look at some sentence examples. We can use some and any with uncountable nouns:
-I've got some money
-Have you got any rice?
