These Three determiners – a, an and the are called “Articles”. They are the most common among all Determiners.

In other words,  An article is a word that modifies or describes the Noun in a sentence.


In the English language, There are two types of Articles.

1. Definite article: As the word Definite means to be exact , obvious or clear about something. It is called definite article because it is used in relation to a particular Noun i.e. Particular thing or person.

The” is the only Definite article in English Language.

2. Indefinite article: As the word Indefinite means to be not exact , neither obvious nor clear about something. It is called Indefinite article because the identity of the thing or person being spoken about in a sentence is left unclear or indefinite.
