Hi Ambitious Girl,
There are a few words concerning the matter in question:
Uncountable nouns are things we cannot count. They have no plural. You cannot say “musics”, “bloods” or “excitements”.
Before uncountable nouns you can say the/some/any/much/this/his etc. But you cannot use
a/an before an uncountable noun.
You can also use uncountable nouns alone, with no article
This ring is made of
gold.
Many nouns can be used as countable or as uncountable nouns. Usually there is a difference in meaning. For example:
I bought a paper. (= a newspaper - countable)
I bought some paper. ( = material for writing on - uncountable)
There is a hair in my soup. ( = one single hair – countable)
She has beautiful hair. ( = hair on her head- uncountable)
Some nouns are usually uncountable in English but often countable in other languages.
Here are the most important of these:
Advice, bread information permission traffic weather
Baggage chaos luggage progress travel work
Behavior furniture news scenery trouble
Countable nouns are things we can count. We can make them plural,
Before countable nouns you can use a/an. Yu cannot use singular countable nouns alone (without a/an/the/my etc)
