countable and uncountable nouns

Countable / Uncountable Nouns
A noun can be countable or uncountable. Countable nouns can be "counted", they have a singular and plural form .
For example:
• A book, two books, three books .....
• An apple, two apples, three apples ....
Uncountable nouns (also called mass nouns or noncount nouns) cannot be counted, they are not seperate objects. This means you cannot make them plural by adding -s, because they only have a singular form. It also means that they do not take a/an or a number in front of them.
For example:
• Water
• Work
• Information
• Coffee
• Sand
Countable
(use a/an or a number in front of countable nouns) Uncountable
(there is no a/an or number with uncountable nouns)

Sources of confusion with countable and uncountable nouns
The notion of countable and uncountable can be confusing.
Some nouns can be countable or uncountable depending on their meaning. Usually a noun is uncountable when used in a general, abstract meaning (when you don't think of it as a separate object) and countable when used in a particular meaning (when you can think of it as a separate object).
For example:-
glass - A glass of water. (Countable) | A window made of glass. (Uncountable)
Some supposedly uncountable nouns can behave like countable nouns if we think of them as being in containers, or one of several types.
This is because 'containers' and 'types' can be counted.
