1. We use the indefinite article, a/an, with count nouns when the hearer/reader does not know exactly which one we are referring to:

Police are searching for a 14 year-old girl.

2. We also use it to show the person or thing is one of a group:

She is a pupil at London Road School.

 

Police have been searching for a 14 year-old girl who has been missing since Friday.

Jenny Brown, a pupil at London Road School, is described as 1.6 metres tall with short blonde hair.

She was last seen wearing a blue jacket, a blue and white blouse and dark blue jeans and blue shoes. 

Anyone who has information should contact the local police on 0800349781.


3. We do not use an indefinite article with plural nouns and uncount nouns:

She was wearing blue shoes. (= plural noun)
She has short blonde hair. (= uncount noun)

Could you please help me?
Is the word "position" in the following sentence right to use or we should use another word.
The university has an international position as a centre of chemistry research.
Thank you.

Hello Ahmed Imam,

Yes, I think that sounds fine. There are several other ways to say this as well:

The university has an international position as a centre of chemistry research.

The university has an international reputation as a centre of chemistry research.

The university has international standing as a centre of chemistry research.

Sir, I want to know if I'm correct in the usage of "an" in the construction below
"Get an Education and not Degree"

Hello Akong,

'An' is correct here, but you also need an article before 'degree:

Get an education and not a degree.

 

As an aside, it is of course possible to get both an education and a degree...

Hello Sir!
1.''John was appointed as superintendent of police, City.''
2. ''He was posted as assistant director research wing.''
''superintendent'' and ''assistant director'' are countable nouns. But in the first sentence, ''a'' and ''an'' are not put before superintendent and assistant director respectively. Would it be correct if I put ''a'' and ''an'' before before it respectively? Sir please explain it to me, and suggest me a link, if there is, where I get to know where one should not use an indefinite article before countable nouns.

Hello ali shah,

There is a choice here. It is possible to use an article or not.

When no article is used the terms Superintendent of Police, City and Assistant Director, Reseach Wing are titles (and shoudl be capitalised), just as we would say elected President or crowned King.

When an article is used the terms are used in a descriptive sense rather than as titles. If you say a superintendent then we understand that there are several superintendents of police, and John is one of them. If you say the superintendent of police then we understand that there is only one such position (but it is a descriptive term, not a title) and John now holds it.

Thank you, Sir. Peter. God bless you.

i want to ask a general question if you don't mind
what is the difference between those three pages for grammar ( English grammar / beginner grammar / intermediate grammar ? and that page in cambridge web site ? and finally how could you advice me to provide my grammar and what can i do to speak well ?

Hi again omarmohamed99,

Generally, the grammar covered in 'Beginner grammar' is lower level than the grammar covered in 'Intermediate grammar'. The 'English Grammar' section isn't classified by level and is a bit more systematic. If there is a specific point you need help on, please ask us and we will help direct you to the appropriate pages.

There is some advice on how to get the most out of our site and how to use it for various purposes (such as improving your grammar and/or speaking) on our Frequently asked questions page.

All the best,
Kirk
