Article : (noun) - a word used with a noun to show whether the noun refers to a particular example of something (the definite article THE in English) or to a general or not already mentioned example of something (the indefinite articles A or AN in English)
In English, it is often necessary to use an article in front of a noun.
There are two kinds of article.
(i) The definite article - THE
(ii) The indefinite articles - A & AN
'How to use the articles' is very important in English. Then alone one can speak well and write well.
Countable nouns : Egg, Insect, Butterfly, etc…
Uncountable nouns : Sugar, Rice, Water, etc…
Note : In usage, countable nouns may be used as uncountable nouns also.
The Egg was bad. (egg - countable noun)
He wiped the egg from round his mouth. (the egg - uncountable)
Is the noun countable or uncountable?
Singular countable nouns always need an article or another determiner like my, this etc….
