The fastest way to learn IELTS vocabulary (free)
Learn 10 to 20 topic words a day as phrases, test yourself before you look at the answer, review each word on a spaced schedule, and use it in a sentence of your own. That takes about 20 minutes a day, and it builds vocabulary you can actually use in Writing and Speaking, not just recognise in Reading.
- Learn 10 to 20 new words per day, as phrases rather than single words
- Test yourself: try to remember the word before you check
- Review words just before you would forget them
- Use each word in a sentence of your own
Key insight
Vocabulary (Lexical Resource) is one quarter of your Writing score and one quarter of your Speaking score, so this habit helps half of the test directly.
IELTS vocabulary by topic: phrases to start with
These topics come up often in Writing Task 2 and Speaking Part 3. Learn each phrase as a whole, then write your own sentence with it.
- Meaning
- deal with a serious problem
- Example
- Governments must work together to tackle climate change.
- Meaning
- produce less pollution from fuel
- Example
- Cities can reduce carbon emissions by improving public transport.
- Meaning
- use too much of something
- Example
- A growing population places a strain on natural resources.
- Meaning
- energy that does not run out
- Example
- Many countries are investing in renewable energy such as solar power.
Learning words in phrases like these is what the Lexical Resource criterion rewards: accurate, natural word combinations.
A simple 20 minute daily plan
Use this structure every day to build vocabulary you can use.
- 5 minutes: review old words
- 10 minutes: learn 10 to 20 new words
- 5 minutes: write 1 or 2 sentences using new words
- Consistency matters more than doing more. A small daily habit beats long, irregular sessions.
Want the reviews scheduled for you?
You can follow this method with paper cards, or use free IELTS flashcards that schedule your reviews and track your progress automatically.
Why this method works
Two well researched learning effects make this method work. Trying to recall a word before you see the answer (retrieval practice) helps you remember it much better than reading it again. Spreading reviews out over days (spaced repetition) helps you remember for longer than studying everything at once.
- Active recall makes you find the word in your memory, which is what you need in the exam
- Spaced repetition shows a word again just before you would forget it
- Sentence practice turns words you know into words you can use
The easiest way to follow this system
You can use a notebook and pen, but then you have to decide what to review and when.
- A flashcard app can show the right word at the right time
- It makes you recall before you check
- It removes guesswork from your study
Note
This system is called flashcards with spaced repetition. ClayLingua IELTS flashcards are free and organised by band and topic. Our free IELTS resources list includes other free options.
Why timing matters when learning vocabulary
Without review, most new vocabulary is forgotten quickly. The key is reviewing at the right time.
- Words you know well appear less often
- Difficult words appear more often
- Each review strengthens long term memory
- After several reviews, you will recall words automatically
Key insight
The difference between band 5 and band 7 vocabulary is not how many words you have seen. It is how many you can use accurately when you need them.
Practise: which word sounds natural?
Choose the word that an English speaker would use. These are common mistakes when ideas are translated word by word.
1I need to ___ a decision before Friday.
2Cities can ___ carbon emissions by improving public transport.
3A growing population ___ a strain on natural resources.
4Many young people ___ heavily on their smartphones.
5Part time jobs help students ___ experience.
Four rules for learning IELTS vocabulary effectively
Follow these rules to make sure your study improves your score.
- 1Rule 1
Focus on IELTS topics
Study vocabulary by topic, such as environment, education, technology, health and work.
GoalBe ready for real exam questions.
- 2Rule 2
Learn collocations
Learn how words are used together in sentences, not just their definitions. Why IELTS Writing gets stuck at band 5 shows how unnatural word combinations lower your score.
GoalUse vocabulary accurately.
- 3Rule 3
Use spaced repetition
Review words at the right time instead of repeating everything every day.
GoalRemember more with less effort.
- 4Rule 4
Limit new words
Learn 10 to 20 new words per day to avoid overload.
GoalStay consistent over the long term.
How many new words per day?
There is no official number of words you need for each band. Lexical Resource looks at range, accuracy and how naturally you use words, not at a word count. So choose a daily number you can keep every day. If your exam is close, how long to prepare for IELTS explains why new words learned in the last week rarely help, and what to do instead.
- 10 new words a day: about 15 minutes. That is about 1,000 words in 14 weeks. A good choice for most students, especially below band 6.
- 15 new words a day: about 20 minutes. Use this if you already have a steady habit.
- 20 new words a day: about 25 minutes or more, because reviews grow with every word you add. Only choose this if you have time every day.
Watch out
Do not raise your daily limit quickly. Your review queue grows with every card you add. Raising the limit too fast creates a queue you cannot finish, and that is when most students give up.

A simple 4 week plan using band based vocabulary
Start at your current level and stay consistent. At 10 new words per day, you will learn 280 new words over 4 weeks. Use your new vocabulary in mock tests and practice exercises.
- 1Week 1
Start at your current band
Begin with the flashcard deck that matches your level (for example, band 3 to 5). Learn 10 new words per day and complete all reviews. Before flipping each card, say or write a sentence using the word.
GoalBuild a daily habit and start turning passive vocabulary into active use.
- 2Week 2
Stabilise and strengthen
Continue with the same deck. Focus on accuracy and correct use, not just meaning. If a word feels difficult, spend more time using it in sentences.
GoalMake vocabulary reliable enough to use in writing and speaking.
- 3Week 3
Keep going as reviews grow
Continue your daily routine and always finish your review queue before learning new words. As your total number of cards grows, your reviews become more important than new learning.
GoalStrengthen long term memory through regular reviews and accurate sentence use.
- 4Week 4
Use it in real IELTS tasks
Write one timed Task 2 essay or record a Speaking answer. Try to use vocabulary you have learned. Afterwards, find missing or incorrect uses. If you are working towards a target band, the band 5 guide and band 6 guide show where vocabulary fits in a full plan.
GoalTurn vocabulary into real exam performance.
A student has 20 minutes to study IELTS vocabulary. They have ClayLingua flashcards open. Which session is most likely to improve their band score?
This student is using flashcards but not improving. Identify what is wrong and rewrite their daily routine with one concrete fix. 'Every evening I open my IELTS flashcard app and go through my review queue. I look at each card, read the word, flip it to check the definition, and mark it as 'remembered' or 'forgotten.' I usually do this for about 20 minutes. I've been doing this for three weeks and my vocabulary feels bigger, but I'm not sure it's showing up in my writing.'
IELTS vocabulary: frequently asked questions
How many words do I need for IELTS?
There is no official number. Examiners judge your range of vocabulary, how accurately you use it and whether word combinations are natural. Learning common topic phrases well is more useful than learning a long list of rare words.
How many new IELTS words should I learn per day?
10 to 20. Ten a day is enough for most students and takes about 15 minutes. More than 20 usually creates a review queue you cannot keep up with.
Should I learn IELTS vocabulary from word lists?
Lists are fine for finding words, but reading them is not enough. Learn each word as a phrase, test yourself before checking, and write your own sentence. That is what makes a word usable in the exam.
Which topics should I learn vocabulary for first?
Start with topics that often appear in Writing Task 2 and Speaking Part 3: environment, education, technology, health and work.
Fit vocabulary into a complete study plan
Vocabulary is one part of your score. See how much time to give it alongside Reading, Writing, Listening and Speaking, with a timetable for every study day.
