It can be categorized into two different categories:

• Definite articles
• Indefinite articles

Definite Article : The definite article limits the meaning of a noun to a specific thing.

“The” is called definite article.

The definite article can be used with singular, plural, or uncountable nouns.

For example,

Please pass me the bottle of water.

In this example, you are pointing to the specific bottle of water. So we are using the definite article “the”.

Indefinite Article :The indefinite article denotes a general noun rather than indicating a specific noun.

“A” and “An” are called the indefinite articles. They are used to specify non-specific objects.
