IELTS Vocabulary Builder: Free Topic Word Lists and Daily Drills

Each list covers a theme that comes up again and again in IELTS Writing Task 2 and Speaking Part 3. The sample words below show the range from Band 5 to Band 8; open a topic for all 15 words with definitions and example sentences.

Which IELTS topics does the vocabulary cover?

The 10 topics match the themes examiners set most often in Writing Task 2 and Speaking Part 3. Learn a list, then practise it on the matching Task 2 topic page.

How is vocabulary marked in IELTS?

Vocabulary is marked as Lexical Resource, one of four equally weighted criteria in both Writing and Speaking, so it is worth about a quarter of your band in each. Examiners look at how wide your range is, how precisely you use it, whether your collocations sound natural, and how accurate your word forms and spelling are. Reading and Listening test vocabulary indirectly, through understanding and paraphrase.

The public band descriptors describe the difference between levels roughly like this:

Summarised from the public IELTS Writing and Speaking band descriptors. See the Writing Task 2 band descriptors and Speaking band descriptors explained for the full criteria.

How do you learn IELTS vocabulary so you can actually use it?

Learn words by topic, with their collocations, and use them in your own sentences before the exam. Recognising a word is not enough; the band score rewards words you can produce accurately under time pressure.

1. 1

   Learn words in topic sets. Study one topic at a time, because IELTS Writing Task 2 and Speaking Part 3 questions are built around themes such as the environment, education and technology.

2. 2

   Learn the collocations, not just the word. Knowing that you 'cut carbon emissions' or 'bridge the digital divide' is what makes a word usable. Read the collocations and the example sentence on each card.

3. 3

   Write your own sentence. Use each new word in a sentence about a real IELTS question. This moves it from words you recognise to words you can produce under time pressure.

4. 4

   Drill and review on a schedule. Take the 10-question daily drill, then review the words you got wrong a day later, three days later and a week later.

5. 5

   Use the words under exam conditions. Write a timed Task 2 essay or record a Speaking Part 3 answer on the same topic, then check whether you used the new words accurately.

How many words do you need for IELTS Band 7?

There is no official word count for any band. Examiners do not count your vocabulary; they judge whether it is wide enough to be flexible and precise, as the Band 7 descriptor puts it. A few hundred topic words that you can use correctly, with the right collocations, will do more for your score than a list of several thousand you only recognise.

That is why this builder keeps each list to 15 carefully chosen words per topic: enough to discuss the theme in depth in an essay or a Part 3 answer, and few enough to learn properly.

Vocabulary for IELTS Speaking and Writing: what is the difference?

The topic words are the same, but the register changes. Writing needs precise, neutral or formal vocabulary; Speaking needs words that sound natural in conversation.

For Speaking practice, pair these lists with the IELTS Speaking topics and the Part 3 questions. For Writing, the Writing phrase bank covers the linking language that sits around your topic words.

Which vocabulary mistakes lower your IELTS band?

Most lost Lexical Resource marks come from using words inaccurately, not from a lack of advanced words. These are the six mistakes that cost candidates most often.

• Wrong collocations

  Words that do not naturally go together, such as 'make research' instead of 'do research', or 'high crime' instead of 'a high crime rate'. Every word in the builder lists its common collocations for this reason.

• The wrong form of the word

  Using a noun where you need an adjective ('an economy solution' instead of 'an economical solution'). Learn the word family together.

• Forcing rare words in

  A Band 8 word used in the wrong place scores lower than a simpler word used precisely. Range only counts when the meaning is right.

• Repeating the question's words

  Copying the wording of the task limits your range. Paraphrase the key terms in your introduction and in your answers to Speaking Part 3.

• Memorised phrases and idioms

  Examiners recognise learned-by-heart phrases. They do not show vocabulary control and can break the flow of a response.

• Spelling and mixed spelling systems

  IELTS accepts British or American spelling, but be consistent. Spelling errors count against Lexical Resource in Writing.

What do the Band 5 to Band 8 word levels mean?

Every word is tagged with a level so you can focus on the words that will move your score.

How we chose and graded these words

The lists are written by the IELTS Prep Studio Expert Team around the themes that recur in IELTS Writing Task 2 and Speaking Part 3. Each word's level is an editorial judgement of how common and how precise the word is, guided by the public band descriptors; it is not an official IELTS grading. Read our methodology and editorial policy for how content is written and reviewed.
