There are two kind of articles in English language definite and indefinite.
There is no doubt that articles are adjectives since they modify the nouns after them. But articles have some special significance as determiners. Articles determine the standard of nouns.

The makes the noun something particular and definite.
Examples
Give me the ball
Here, the speaker is telling someone to give him/her a particular ball about which the speaker and the listener both are aware. There is no possibility of the ball to be anything else rather than the speaker and the listener idea of that particular ball.
- Indefinite Article – a & an
A & an – make the noun something general and indefinite.
