The question
Why do we say an hour, a university and the sun?
Use a/an with singular countable nouns when introducing one nonspecific member of a class: I saw a dog. Use the when the listener can identify the referent: The dog was barking. Plural and uncountable nouns often have no article when referring generally: Dogs are friendly; Water is essential.
Choose by meaning and sound
| Choice | Example | Reason |
|---|---|---|
| a | a university | The word begins with a /j/ consonant sound. |
| an | an hour | The initial h is silent, so the word begins with a vowel sound. |
| the | Please close the door. | The particular door is identifiable in context. |
| no article | I like music. | Music is an uncountable noun used generally. |
Article choice depends on pronunciation rather than the first written letter: an honest person, a European city. The is also used for some unique or contextually unique referents, such as the sun, but there are idiomatic patterns and place-name exceptions (the Netherlands, France).
Common mistake
Avoid *I bought book: a singular countable noun generally needs a determiner (I bought a book). Avoid *The life is short for general statements: Life is short.
Remember
Ask whether the noun is singular and countable, whether the listener knows which one, and—when choosing a/an—what sound begins the next word.
