Indefinite Articles

Indefinite articles (a/an) are determiners and are used to express non-specific things or general categories. They are placed before singular countable nouns, noun phrases and adjectives.

There are two indefinite articles:

• A when the noun or adjective begin with a consonant.
• An when the noun or adjective begin with a vowel or h that is not pronounced.

For example:
— “There’s a tourism office around the corner.” = We use a before a word starting with t- (consonant).
— “There’s an information office around the corner.” = We use an before a word starting with i- (vowel).

We use the indefinite article to express something general, which has never been mentioned before.

♦ “The information office around the corner…” = We use the definite article (the) since we know what we are talking about.
