English has two kinds of article: the indefinite article (a / an) and the definite article (the). Sometimes no article is needed at all (the “zero article”). For speakers of languages without articles, such as Polish or Russian, they are one of the hardest parts of English, but a handful of rules covers most situations.
The three options at a glance
| Article | Use | Example |
|---|---|---|
| a / an | one of many; the first time we mention something; a job or a type | I saw a dog. She is an engineer. |
| the | a specific thing both people know; unique things; a second mention | The dog was big. The sun is hot. |
| no article | plural or uncountable things in general; most names and meals | Dogs are loyal. I like music. |
A or an?
Choose by the sound of the next word, not by its spelling. Use an before a vowel sound and a before a consonant sound.
| Rule | Examples |
|---|---|
| an + vowel sound | an apple, an egg, an idea, an old house |
| a + consonant sound | a book, a house, a university /juː/, a European city /jʊ/ |
| an + silent h | an hour, an honest man, an honour |
| a + sounded h | a hotel, a horse, a happy child |
When to use a / an
- The first mention of a singular countable noun: I bought a car.
- A job or role: He is a doctor. She works as a waiter.
- A kind or class: A cat is a pet.
- Per: twice a week, 50 km an hour, £3 a kilo.
- After such, what, quite, half: such a good idea, what a surprise, quite a long way.
Only singular countable nouns take a / an. Never use it with plurals (a books) or uncountable nouns (an information, a advice) – say some information, a piece of advice.
When to use the
- Something already mentioned: I bought a car. The car is red.
- Something clear from the situation: Close the door, please. (the door of this room)
- Unique things: the sun, the moon, the sky, the world, the internet.
- Superlatives and ordinals: the best, the first, the only, the same.
- Some geographical names: the Alps, the Atlantic, the Netherlands, the United States, the Thames.
- Musical instruments: She plays the piano.
- Groups of people: the rich, the French, the young.
When to use no article
| Case | Examples |
|---|---|
| Plural and uncountable nouns in general | I like cats. Water is important. Life is short. |
| Most countries, cities and continents | He lives in Poland. We visited Paris. Asia is large. |
| Meals | We have breakfast at eight. Lunch is ready. |
| Languages and school subjects | She speaks Spanish. I study biology. |
| Sports and games | They play football. He likes chess. |
| Fixed phrases with places (the institution, not the building) | go to school, in hospital, at work, in bed, go to church, at home |
| Transport with “by” | by car, by train, by bus, on foot |

Frequently asked questions
How do I know whether to use “the” or “a”?
Ask yourself: does the listener know exactly which one I mean? If yes, use “the”. If it is any one, or new information, use “a / an”.
Why do we say “the United States” but “Poland”?
Names that are plural or contain a word like republic, kingdom, union or states take “the”: the Czech Republic, the United Kingdom, the Netherlands. Most single-word country names take no article.
Can I leave out articles in short texts, such as headlines?
Yes. Headlines, notes and signs often drop articles (“Man finds wallet”), but in normal sentences they are required.
