We use the indefinite article, a/an, with singular nouns when the listener/reader does not know exactly which one we are referring to:
Police are searching for a 14-year-old girl.
We also use it to show that the person or thing is one of a group:
She is a pupil at London Road School.
Police have been looking for a 14-year-old girl who has been missing since Friday.
Jenny Brown is a pupil at London Road School. She is 1.6 metres tall, with short, blonde hair. When she left home, she was wearing a blue jacket, a blue and white blouse, dark blue jeans and blue shoes.
Anyone who has information should contact the local police on 0800 349 781.
