What is an Article?

An article is a word that comes before a noun to define its definiteness or indefiniteness. Articles help us know whether we’re referring to something specific or something general.

In English, there are three articles:

• “A” – Indefinite article used before consonant sounds.
• “An” – Indefinite article used before vowel sounds.
• “The” – Definite article used before specific or previously mentioned nouns.

Articles are part of a broader category called determiners, which also includes this, that, some, many, etc. But articles are unique because they always come before a noun to determine whether it’s specific or general.

Why are “a,” “an,” and “the” called Articles?

The words “a,” “an,” and “the” are called articles because they are used to introduce nouns and give clarity about their reference.

• “A” and “An” are indefinite articles, meaning the noun they introduce is not specific.
• “The” is a definite article, meaning the noun it introduces is specific or known to the reader or listener.

1. “A” and “An” – Indefinite Articles:
