The indefinite article: 'a' and 'an'
Level: beginner
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.
We do not use an indefinite article with plural nouns or uncount nouns:
She was wearing blue shoes. (plural noun)
She has short, blonde hair. (uncount noun)
- The indefinite article 1
- The indefinite article 2
- The indefinite article 3
We use a before a consonant sound:
| a banana (starts with /b/) | a university (starts with /j/) |
and an before a vowel sound:
| an orange (starts with /o/) | an hour (starts with /au/) |
Note that the choice of a or an depends on sound, not spelling.
- The indefinite article 4
Dear LearnEnglish team,
Why in this example, "Police have been looking for a 14-year-old girl who has been missing since Friday", the girl has an indefinite article? Don't we have to say "the 14-year-old girl", because there's an explanation which particular girl police is in search of, "who has been missing since Friday"?
Best wishes,
Katja
Hello Katja,
This is an example of the indirect article for first mention of something. The assumption here is that the reader does not yet know about the girl being missing - this is the reader's first news on the topic. In fact, the relative clause (...who has been missing for...) indicates this. It is a defining relative clause which tells us which 14-year-old girl we are talking about and it introduces its information as new information. If the reader already knew the girl was missing then the sentence would simply use a descriptive phrase:
Police have been looking for the missing 14-year-old girl since Friday.

Hello, I have a question.
Why is an the answer to the 7th question in the 4th exercise? Shouldn’t it be a since the word starts with 'm'?
Thank you!
Hello kamobi,
The use of a and an is determined by the pronunciation and not the spelling. Here, the acronym MBA is pronounced as three letters: "EM" "BEE" "EY". We use an because EM begins with a vowel sound.
Sometimes the same letter is pronounced differently in different words. For example the letter u is sometimes pronounced like "UH" (ugly, unkind, upper) and sometimes like "YOU" (usual, uniform, university). Thus we say these:
an ugly building, an unkind person, an upper-management position
but we say
a usual day, a uniform for a police officer, a university degree.

Hi the LearnEnglish Team,
I have one question.
Why in the sentence "Police are searching for a 14-year-old girl" word "police" had been used without the definite article "the"?
In the next article about using "the" saying that "police" as a service must be written with "the".
Thank you for the answer
Polemnn
Hello polemnn,
It's a subtle difference. When we say 'Police are searching ...' it's not so much about a service as actual police officers out in the field looking for someone. We could also say 'The police' here, and this would refer to the police as a service, but for some reason we tend to think of the human police officers in such a case.
Hope this helps.
Best wishes,
Kirk

Hello Kirk,
The police, if refers to the police as a service, will take a singular verb, won't it?
The we would say "The police is looking for...", wouldn't we?
Shetu Yogme.
Hello ShetuYogme,
Yes, that's correct. If we are thinking of the police as an institution or a service then we generally use a singular verb. If we are thinking of the police as a group of people then a plural verb is used. This is true for similar organisations such as teams (Manchester United), political groups (the Democratic Party), political organisations (The United Nations, the European Union) and so on.

Hi,
Can you please clear out my confusion on use of article a/an in below sentences :
1. She is as beautiful "a" girl as you are ever likely to meet.
2. It was so forceful "a" blow
3. He was too valuable "an" asset.
I am not fully able to digest why article is needed. For example, the 3rd sentence can be modified to "He was too valuable asset" - If I am not wrong, it conveys the same meaning.
Thanks in Advance.
Regards,
Abhay
Hi abhaykumar,
Actually, the article is necessary and without the article, the sentences are not grammatical. The article is needed because a singular noun needs a determiner, and an article is a type of determiner. The modifying phrases (e.g. so forceful) are not determiners themselves, i.e. they cannot replace the article - they just modify the noun.

Hi
is there a difference when we say "The police" instead of '' Police " in this sentence "Police are searching for a 14-year-old girl.".
Hello Ahmed Hassan,
No, there's no difference.

Hello Teacher Peter
What about these "I will study until the school starts" and "I will study until school starts". are they the same with and without the definite article before the word "school"?
Hello Ahmed Hassan,
The second sentence (without 'the') suggests that the speaker is a student at the school. The first sentence does not suggest this. They may be simply using a room which they will have to vacate when lessons begin, for example.
Peter
The LearnEnglish Team
Hello Mr. Peter,
Could you kindly explain why is there such as difference?
Hello Panni Nous,
...until school starts does not refer to a building, place or particular school, but rather to the beginning of the school day or year, just as 'until work starts' refers to the beginning of a period of work.
...until the school starts describes a particular school.

Hello Nevi,
I'm not sure what your question is here! It seems like you have a pretty good grasp of the topic as your explanation of your example is correct. If you substitute 'the' for 'a' here then you would be asking about a specific and known item, not just any item.
I want a computer = any computer is fine; it doesn't have to be a particular one
I want the computer = you know which one I want; maybe it's the only one we have, or maybe it's one we've talked about already
Peter
The LearnEnglish Team
Hello Nevi,
We use 'a' with singular nouns, so it refers to one item rather than more than one. It also tells us that the speaker is not talking about a particular computer. The answer to your question, therefore, is that 'a' carries both of these meanings, not just one of them.

Hello Nevi,
In 99.9% of situations people would mean that they have one brother by saying this. In a very specific (and unusual) context in which the speaker was, for example, trying to hide the fact that they have more than one brother, it could mean that the speaker has at least one (not a particular) male sibling, but that is quite unusual. As I said, in the vast majority of situations, they would say 'I have two brothers' (or however many brothers there are) instead of 'I have a brother'.
As I said, the unusual case I mentioned is extraordinarily rare, so in general you can count on this meaning that the speaker has one brother.
All the best,
Kirk

Hello again Nevi,
I think you're looking for a grammatical rule here where it's really more the intention of the speaker which matters.
When a person says 'I need a telephone' they're generally not talking about the phone itself but rather the call: I need to call someone. The number of phones is not really in their mind. The only time you would say 'I need one phone' is when for some reason two or three or more would cause you problems for some reason.

Hello Ahmed Imam,
I don't think we would use either construction. You need to include an adjective of some kind:
Alternatively, you could use a phrase like this:
Peter

Hello Ahmed Imam,
Both are possible. I don't think there's any difference in meaning so it's really a question of personal choice and linguistic background (idiolect and dialect).

Hi tanipetrush,
There is no article here because we are talking about spiders in general. If we were talking about a particular spider then we would use 'a spider' for first mention and 'the spider' later (or 'spiders' and 'the spiders' for more than one spider), but for general meaning we do not use any article.

Hello Dipak,
The phrase '...is history' is a fixed expression. It means something is done, finished or ended. It can also mean that something or someone has been defeated.
We only use 'a history' in the context of a book: this is a great history of the Roman Empire.

Hello Ahmed Imam,
I think 'Sudan' is becoming more and more common, but you can still hear 'the Sudan'. However, this is a political question as much as a language question following the secession of South Sudan in 2011.
Peter

Hi dipakrgandhi,
Good question! It's because in this sentence, US is describing the other noun, passport. US isn't the main noun in the phrase. So, the article we choose depends on the main noun, passport (not on any other nouns that describe it).
Does that make sense?
Jonathan
The LearnEnglish Team
Hi Dipak,
Yes! Exactly :)
Jonathan
The LearnEnglish Team
Hi dipakrgandhi,
Yes! You may have seen some examples like these.
In those examples, the meaning is 'very' or 'extremely'. This is different to, for example, She was the most valuable member of the team, which means she was the 'number one most valuable' or the absolute best.
Using the indefinite article with most in this way is a relatively formal in style. We can only use this structure with most - we can't use it with single-word superlatives (e.g. we can't say 'It was a best meal').
About your sentence, it should be most of the time (without the before most, and with time instead of times).
Does that make sense?

Hello knownman,
There are several possibilities here, depending on whether you are using a title or a description of a position:
This is his title
This is his position; there is only one such position.
This is his position; there are several such positions; he is one of several.
As the word 'professor' is capitalised, I assume the write was using it as a title, so no article makes sense.
'Head of Department' functions in a similar way.

Hello Ahmed Imam,
The second version (with 'the') is correct. Railway networks, including underground networks, usually take the definite article unless we are dealing with the name of a company:
