Countable and Uncountable Nouns: Rules, Examples, and Common Mistakes

In English grammar, nouns are classified into countable and uncountable categories. Understanding the difference is essential for correct sentence construction and grammar usage.

1. What Are Countable and Uncountable Nouns?

Countable Nouns

Countable nouns are objects, people, animals, places, or ideas that can be counted. They have singular and plural forms and can be used with numbers or words like a/an, many, a few, some, several, a number of.

✅ Examples:

Uncountable Nouns

Uncountable nouns refer to substances, abstract ideas, or masses that cannot be counted as individual units. They do not have plural forms and usually take singular verbs. They are used with words like much, a little, some, a lot of, a great deal of.

✅ Examples:

• water – I need some water.
