Use a or an before a singular noun when the listener does not know which one: a laptop, an idea. Use the when the listener knows which one: the laptop I bought. Use no article for plural or nouns in general statements: Technology changes life.
The three choices
Most nouns in English need one of three choices before them: a or an, the, or no article (called the zero article). The choice depends on one question: does the listener or reader know exactly which one you mean?
If not, or if it is one of many, use a or an. If yes, use the. If you are talking about things in general, use no article.
A and an: one of many
Use a or an with singular nouns when the thing is new to the listener, or when you are naming a job or a type: I bought a laptop. She is an engineer. It was a difficult exam.
The choice between a and an depends on the sound, not the spelling. Use an before a sound: an idea, an hour (the h is silent), an MBA. Use a before a sound: a university (it starts with a y sound), a European country, a one-way ticket.
- an apple · vowel sound
- a university · consonant sound
- an hour · silent h
The: both of you know which one
Use the with any noun when the listener knows exactly which one. This happens in four main ways. First, it was mentioned before: I bought a laptop. The laptop is very fast. Second, it is clear from the situation: Please close the door. Third, there is only one: the sun, the government, the internet, the environment. Fourth, a phrase or clause makes it specific: the city where I grew up.
Also use the with superlatives (the best, the largest), ordinal numbers (the first, the second), and a few fixed groups such as the UK, the USA, the Netherlands and the Pacific Ocean.
No article: general ideas
When you talk about a whole group or a general idea, use no article with plural and nouns: Children need exercise. Water is essential. Education improves lives. Technology has changed communication.
This is the most common source of mistakes in IELTS essays. Compare: Education is important (in general, no article) and The education in my country is free (specific, so the). Both are right, but only when the meaning fits.
Most names of countries, cities, languages and meals take no article: Japan, Paris, Spanish, lunch.
Fixed expressions
Some phrases keep or drop the article by habit. People go to school, to university, to hospital, to work and to bed (as a student, patient or worker), without the. But we say the school is closed or I went to the hospital to visit her when we mean a particular building.
Use the with the media, the poor, the elderly and the rich. Do not use the with next week, last year or in 2020.
Quick test
Ask three questions. Is it a singular noun? If it is, you need a, an or the. Does the listener know which one? If yes, use the. Is it plural or , and general? If yes, use no article. This short test fixes most errors.
- singular, new, not specific: a or an
- specific, known or unique: the
- plural or uncountable, general: no article
Think in order
Remember the order of thinking. First decide whether the noun is and singular. Then decide whether your reader knows which one you mean. Finally, check whether you are speaking in general. Practise by taking a paragraph from any text you read and explaining each article aloud. After a few paragraphs the choices start to feel automatic, and you will notice that the same small set of reasons returns again and again.
Common mistakes
These are the mistakes IELTS candidates make most often:
- The education is the key to success. Say: Education is the key to success.
- The people should recycle more. Say: People should recycle more.
- I am student. Say: I am a student.
- She has an university degree. Say: She has a university degree.
- I like the music. Say: I like music, when you mean music in general.
- He plays the football every weekend. Say: He plays football every weekend. Sports take no article.
Who finds this hard?
- Japanese speakers: Japanese has no articles, so a, an and the can feel invisible. Ask whether the reader knows which noun you mean, and add a, an or the if the noun is singular.
- Korean speakers: Korean has no articles. The simple test (singular? known? general?) will give you the right choice more reliably than guessing.
- Chinese speakers: Chinese has no articles. Drop them for general plural and nouns, and add a, an or the for singular nouns.
- Turkish speakers: Turkish has no the, and uses the word bir for one thing, which looks like a. Learn when English needs the instead.
- Arabic speakers: Arabic has a definite article (al-) but no a or an, and it uses it differently. In English, general ideas take no article: Education is important, not The education is important.
IELTS tip
Articles show up in every part of the test, and they matter most in Writing, where a missing or extra the is easy to spot. After you write, scan every singular noun for a, an or the, and check every general plural noun for an unwanted the.
Frequently asked questions
What is the difference between a and the?
A refers to one of many, or to something new. The refers to something both people already know about, or the only one.
When do I use no article?
Use no article with plural and nouns when you talk about things in general, such as Children need exercise or Water is essential.
Why do we say an hour but a university?
The choice depends on sound. Hour starts with a sound, since the h is silent. University starts with a y sound, which is a sound.
Do I need an article before every noun?
Every singular noun needs one (a, an, the or another word like my or this). Plural and uncountable nouns may take no article.
