IELTS Grammar: When to Use A, An and The in Writing

Quick answer: Use the when the reader already knows which one you mean. Use a or an when you introduce something for the first time or when any one would do. Use no article for plural or uncountable nouns meant in general, which covers most of a Task 2 essay.↗ Share on X
Use the when the reader already knows which one you mean. Use a or an when you are introducing something for the first time or when any one of them would do. Use no article when you are talking about things in general, in the plural or uncountable. That is the whole system, and almost every article mistake in IELTS Writing comes from skipping the first question: does my reader already know which one?

The 8-Minute Essay Outline That Lifts IELTS Task 2 Scores →Before you write a noun, ask: *can the reader point to it?*
- "I bought a book." — Which book? The reader has no idea. First mention.
- "The book was expensive." — Now the reader knows. Second mention.
Everything else is a version of that same test.
The reader can "point to it" for four reasons: you mentioned it before, you describe exactly which one, there is only one of it, or the situation makes it obvious. Each of those is covered below.

A or an depends on sound, not spelling
The rule taught in most classrooms is "a before consonants, an before vowels." That rule fails in the exact places examiners notice.
The real rule: an before a vowel *sound*, a before a consonant *sound*. Say the word out loud and listen to the first sound.
| Phrase | Correct | Why |
|---|---|---|
| a university | a | Starts with a "yoo" sound |
| an hour | an | The h is silent, so it starts with "ow" |
| a European country | a | Starts with "yoo" |
| an honest answer | an | Silent h again |
| a one-way street | a | Starts with a "w" sound |
| an MBA | an | The letter M is said "em" |
| a UK citizen | a | Said "yoo-kay" |
| an umbrella | an | Ordinary vowel sound |
If you are unsure during the test, say the word silently and listen. Your ear is more reliable here than the spelling.

*A new hospital opened last year. The hospital employs 400 people.*
2. There is only one. The sun, the moon, the internet, the environment, the government of a named country.
*Pollution is damaging the environment.*
3. You say exactly which one. Usually with "of" or a clause after the noun.
*The number of students increased.* / *The chart that shows exports is clearer.*
4. Superlatives and ordinals. The biggest, the highest, the first, the last.
*The highest figure was recorded in March.*
Two more that matter in IELTS: the goes with country names that are plural or contain a common noun (the United States, the Netherlands, the UK), and with rivers, seas and oceans (the Nile, the Pacific). It does not go with most single-word country, city or continent names.
When you should use no article at all
This is the gap that costs band score most often, because learners over-correct and add "the" everywhere.
Use no article when you talk about something in general:
- *Children learn languages quickly.* (children in general)
- *The children learn languages quickly.* (specific children you already mentioned)
- *Education should be free.* (education as a concept)
- *Water is essential.* (uncountable, general)
Also no article with:
- most country, city and continent names: *Japan, Paris, Africa*
- meals: *before breakfast*, *after lunch*
- most languages and school subjects: *He studies history*
- fixed phrases: *at home, by car, at night, in prison, to school*
The general-meaning rule is the single most useful one for IELTS Writing Task 2, because Task 2 essays are almost entirely about things in general.
The mistakes examiners see over and over
| What learners write | Correct | The rule being broken |
|---|---|---|
| The people are living longer | People are living longer | General meaning takes no article |
| I am doing the research on climate | I am doing research on climate | Uncountable and general |
| The society faces many problems | Society faces many problems | General concept |
| In the nowadays | Nowadays | No article with this word |
| The most of students | Most students | "Most" needs no article here |
| I went to the university in 2019 | I went to university in 2019 | Institution as an activity, not a building |
| The graph show a increase | The graph shows an increase | "an" before a vowel sound |
| The both countries | Both countries | No article with "both" |
| In the 1990s the unemployment rose | In the 1990s unemployment rose | General, uncountable |
Copy that table into a notebook and check your own essays against it. Most candidates repeat the same two or three of these errors in every single essay, which is good news: fixing two habits fixes most of the problem.
Where articles appear in Task 1 and Task 2
In Task 1 (charts and processes), these patterns repeat constantly:
- *The chart shows...* — only one chart in front of you, so "the".
- *The number of visitors rose.* — "the number of" always takes "the".
- *A sharp increase occurred in 2015.* — first mention of that increase.
- *The highest figure was in June.* — superlative.
- *Sales fell.* — general plural, no article.
In Task 2 (opinion essays), the general rule dominates:
- *Governments should invest in public transport.* (general, plural, no article)
- *The government of Singapore introduced a tax.* (specific, named)
- *Technology has changed education.* (both general and uncountable)
A simple habit: in Task 2, if the noun is plural or uncountable and you mean it generally, leave the article out and move on.
Articles in IELTS Speaking: relax a little
Examiners in the Speaking test listen for communication, fluency and range, and natural speech contains small slips that nobody notices. Stopping mid-sentence to work out whether a noun needs "the" damages fluency far more than the missing article ever would.
So treat the two parts of the exam differently:
- In Speaking, keep talking. If you hear your own mistake, correct it in passing and move on, the way native speakers do.
- In Writing, you have time to check, which means the examiner reasonably expects more accuracy from you.
That split matters because many candidates practise articles in a way that makes them slower and more hesitant when speaking, and then score lower on fluency while trying to fix grammar.
A five-minute drill you can repeat
Do this with any essay you have already written.
1. Print or copy your essay and underline every noun.
2. For each one, ask the pointing question: can the reader point to exactly which one?
3. If yes, it should have the. If no and it is singular countable, it needs a or an. If it is plural or uncountable and general, it needs nothing.
4. Mark the ones you got wrong and write only the corrected phrase, not the whole sentence, in a list.
5. Read that list of corrected phrases out loud twice.
Repeating corrected phrases aloud does more than rereading rules, because articles are eventually a matter of reflex. You want the right version to sound normal to you under time pressure, when you have no spare attention for grammar analysis.
One habit to build before the exam
Keep one page in your notebook titled "my article errors." Every time a teacher or a checker corrects an article in your writing, add the phrase — both versions, wrong and right.
Within a few essays you will notice the page repeats itself. Almost nobody makes ten different article mistakes; most people make the same three in rotation. Once that page shows you which three are yours, you know exactly what to check before you hand in your writing, and you can do it in the last two minutes of the exam without rereading every sentence.
Start that page with your most recent essay, today.
FAQ
Why is it 'an hour' but 'a university'?
Because the rule follows sound, not spelling. The h in hour is silent, so the word starts with a vowel sound and takes an. University starts with a yoo sound, which is a consonant sound, so it takes a. Say the word to yourself and listen to the first sound.
Do article mistakes lower my IELTS Writing band?
Articles fall under grammatical range and accuracy, which is one of the four marking criteria. Occasional slips matter less than repeated errors in simple sentences. Since most candidates repeat the same two or three article habits, correcting those habits improves accuracy across the whole essay.
Should I write 'the people' or 'people' in a Task 2 essay?
Write people when you mean people in general, which is almost always the case in Task 2. Use the people only when you have already identified a specific group, such as the people living in rural areas mentioned earlier in the paragraph.
