The Indefinite Article (A or An).
We use A/An with singular, countable nouns when mentioning them for the first time.
They have two children, a boy and a girl.
There's a new hospital in the city centre. (See notes 24, 28 &29 below)
We use 'A' before a noun or adjective which begins with a consonant sound.
I'd like a cup of tea. She's got a blue bag.
We use 'An' before a noun or adjective which begins with a vowel sound.
I'd like an orange juice. She's got an exceptional memory.
Sometimes a word begins with a consonant, but the word has a vowel sound. In this case use 'An' (see note 4 below)
I'll see you in an hour. (pronounced /AU UH/) She's doing an MBA. (pron. /EM BEE AY/)
Sometimes a word begins with a vowel, but the word has a consonant sound. In this case use 'A'.
He's got a European car. (pron. /YOOR UH PEE UN/) Is there a university in Campos? (pron. /YOO NI VER SI TEE/)
NOTE!
In some countries, the word for A/An is the same as the word for the number 1. In English we
only use '1' when we want to specify that there are not two, three or four of something.
She's got a new car.
Has she got two cars?
No, she hasn't. She's only got one car.
