In Modern English Grammar Nouns are broadly divided into two Categories— (a) Countable Noun (b) Uncountable Noun.
Countable nouns are easy to recognize. They are things that we can count.
For example: "pen". We can count pens. We can have one, two, three or more pens. Here are some more countable nouns:
- dog, cat, animal, man, person
- coin, note, dollar
- cup, plate, fork
- table, chair, suitcase, bag
Countable nouns can be singular or plural:
We can use the indefinite article a/an with countable nouns:
- A dog is an animal.
When a countable noun is singular, we must use a word like a/the/my/this with it:
- I want an orange. (Not I want orange.)
- Where is my bottle? (Not where is bottle?)
When a countable noun is plural, we can use it alone:
- I like oranges.
- Bottles can break.
We can use some and any with countable nouns:
- I've got some dollars.
- Have you got any pens?
We can use a few and many with countable nouns:
- I've got a few dollars.
- I haven't got many pens.
Uncountable nouns are substances, concepts etc that we cannot divide into separate elements. We cannot "count" them. For example, we cannot count "milk". We can count "bottles of milk" or "litres of milk", but we cannot count "milk" itself.
Uncountable nouns (also Known as non-count nouns or mass nouns)
