Useful examples
I have a new phone.
I have one new phone.
Use a because the phone is introduced for the first time and is not specific.
She is an English teacher.
She works as an English teacher.
English starts with a vowel sound, so we use an.
He bought a car yesterday.
He bought one car yesterday.
The listener does not know which car it is.
I saw a woman waiting outside the station.
A woman was waiting outside the station, and I saw her.
The woman is introduced for the first time, so a is appropriate.
The woman was talking on her phone.
That woman was talking on her phone.
The listener can now identify the woman from the previous context.
My brother wants to buy a used car.
My brother wants to get one used car, but no particular car has been identified yet.
A is used because the car is singular, countable, and not yet specific.
I study English as a foreign language.
She lives in France.
He is from the United States.
We sailed on the Nile.
Breakfast is ready.
The breakfast at the hotel was excellent.

Learning tips
- Remember: a/an usually means one, while the means a specific one.
- Choose a or an by sound, not only by spelling.
- Before choosing an article, ask whether the noun is countable or uncountable. If it is countable, also check whether it is singular or plural.
- To choose between the and the zero article, ask whether you mean something specific or a category or concept in general.
