English articles
The short answer
Use a or an when you mention a countable thing for the first time, or when any one of a kind will do. Use the when both speaker and listener know which one is meant. Use no article for plurals and uncountables spoken of in general: cars are expensive, water is free.
Or skip ahead and practise it now: articles a, an, the, free, no signup.
The rule
English marks a noun as either identified or not. The indefinite article a or an introduces one unspecified member of a class and appears only with singular countable nouns. The definite article the marks a noun both speaker and listener can identify, whether from earlier mention, from context, or because it is unique. The zero article (no article at all) is used for plurals and uncountable nouns talked about in general. The choice depends on shared knowledge rather than on the noun itself, which is why the same noun takes all three at different moments.

|---|---|---|
| a / an | first mentionsingular countable | I bought a car. |
| the | already knownor unique | The car broke down. |
| no article | plural or uncountablein general | Cars are expensive. |
| a or an | by soundnot spelling | a university, an hour |
| the | with superlatives and ordinals | the best, the first |
| no article | with most names | France, London, Mount Fuji |
Part 1 of 3
First mention, then the
The core pattern is a sequence. Introduce something with a or an, then refer back to it with the: I saw a fox in the garden. The fox was eating something. Once it has been introduced, both speaker and listener can identify it.
The also works without any earlier mention when context identifies the thing: pass me the salt, close the door, the manager will see you now. There is only one relevant salt, door and manager, and everyone present knows which.
She’s got a new job. The job starts in March.
Introduce, then refer back.
Could you turn off the light?
Context identifies it.
The sun was low.
Unique, so always the.
Part 2 of 3
The zero article
Plural and uncountable nouns used in a general sense take no article at all: dogs bark, information is free, happiness matters. Adding the would narrow the statement to particular dogs or particular information.
This is the half that speakers of article-less languages find least intuitive, because it looks like the article has simply been forgotten. It has not: the absence is meaningful, and it is what makes cars are expensive a claim about cars in general.
Books are cheaper online.
Books in general.
The books you ordered have arrived.
Specific ones, so the.
I like music, especially the music they played last night.
General, then specific, in one sentence.

Names, institutions and fixed phrases
Most proper names take no article: France, London, Mount Fuji, Lake Como. But plural and descriptive names take the: the Netherlands, the Alps, the United States, the Thames, the Sahara.
Institutions split by whether you mean the activity or the building: go to school, be in hospital, go to prison describe the purpose; go to the school, be in the hospital describe the place. British and American English differ on hospital in particular.
She’s from the Netherlands.
Plural name, so the.
He’s in prison. / She works at the prison.
The activity, then the building.
We go to church on Sundays.
The activity, so no article.
Mistakes to avoid
What learners actually get wrong
I am teacher.
I am a teacher.
A singular countable noun needs an article, and professions take a. Many languages omit it here, so this transfers directly and is one of the first errors to appear and the last to go.
The life is hard.
Life is hard.
An uncountable noun in a general sense takes no article. Adding the narrows it to a particular life, which turns a general observation into a statement about someone specific.
an university
a university
The choice depends on sound, not spelling. University starts with a y sound, so it takes a, while hour starts with a vowel sound and takes an.
I went to the France last summer.
I went to France last summer.
Most country names take no article. The exceptions are plurals and descriptive names, the Netherlands, the United Kingdom, the Czech Republic, where the is required.

Questions
Asked and answered
- Why is this so hard?
- Because many languages have no articles at all, Russian, Polish, Czech, Japanese, Korean, Mandarin, so there is nothing to map onto. The decision is also not about the noun but about what the listener already knows, which means the same noun takes different articles in consecutive sentences.
- Is there a shortcut for a and an?
- Say the next word aloud. A vowel sound takes an, a consonant sound takes a. That is why it is an hour but a university, an MP but a member. Spelling will mislead you; pronunciation will not.
- When do I use the with a general statement?
- With a singular noun standing for a whole class, usually in formal or technical writing: the elephant is endangered, the smartphone changed everything. In ordinary English the plural with no article, elephants are endangered, is far more natural.
