A / an / the
- a + consonant sound: a dog.
- an + vowel sound: an orange.
- the + a special or known thing: the moon.
No article
- We do not use a/an before plural or uncountable nouns in general: I like rice. Dogs are loyal.
Key idea
'a/an' for one general thing, 'the' for a known thing; no 'a/an' before plural or uncountable nouns in general.
Remember
Choose 'a' or 'an' by the sound, not the letter: an hour, a university.
