Indefinite Articles – A versus An

What are Indefinite Articles?

The words a and an are called indefinite articles. We can use them with singular nouns to talk about any single person or thing.

Deciding which indefinite article to place in front of a word depends upon the initial sound of the word, not the first letter of the word.

When to Use “A”

A’ is used before words beginning with a consonant sound.

E.g.

A man

A hat

A lamp

A teacher

When to Use “AN”

The article ‘an’ should be placed before words that begin with a vowel sound.

The initial sound should be a, e, i, o, or u.

E.g.

An apple

An egg

An island

An article
