Improve your IELTS Vocabulary for Speaking

Why is it important to improve your IELTS vocabulary for speaking?

Because, this is also the one area that most differentiates a band 6, 7, 8 and 9.

What’s more, the one area where you can make the biggest and fastest improvement in your speaking, is vocabulary…

 …if you study it correctly!

Learn how to learn vocabulary for IELTS Speaking

  1. Always make sure you learn vocabulary in context.
    • The context shows you when and how to use the language, and also what words go together
    • Word lists, idiom lists have limited use because they have no context. 
  2. When learning vocabulary, make a note of phrases, not single words. 
  3. Learn the collocations of the word.
    • E.g. don’t just learn ‘tea’, learn ‘black tea’, ‘milky tea’, ‘a tea party’…
  4. As well as writing new language, you can also record phrases that you can listen to many times.
  5. Learn at least two synonyms for commonly used words (e.g. like, good, often…)

Extend your passive vocabulary.

You have 2 kinds of vocabulary.

  1. Words you recognise when you see or hear them (passive vocabulary)
  2. Words you can actually use when speaking or writing (active vocabulary).

You need to extend both of these in order to improve your vocabulary for IELTS speaking.

Let’s look first how to extend passive vocabulary.

It’s simple, practice passive skills (reading and listening).

  1. Go beyond your course book
    • Read magazines, newspapers, novels, poems, recipes, blogs, anything you can get your hands on.
  2. Go beyond your teacher
    • Listen to English everyday, including, podcasts, radio, videos, films, and even real people!

Activate your vocabulary

Now, let’s look at how to activate your vocabulary (i.e. move it from passive to active).

There are only 2 ways to do this, speaking and writing; this is why they are called the active skills!

Remember, just because you can write a word, doesn’t mean you can speak it. 

You need to practice both skills.

Here are some ideas;

  1. Do some detailed listening; that means, listen and make notes of new language (words, phrases and idioms).
  2. Record the new words and phrases and listen back to them lots.
  3. When you listen, repeat the new words and practice making new phrases with them. 
    • This will let you hard-wire new vocabulary.
    • It starts to fix the language in the speaking part of your brain.
  4. Create conversations (with a speaking partner or teacher) where you can start practicing this new language.
    • This will make it a part of your everyday speech.

TIP

Remember, in the exam, you will probably use language at level somewhat lower than what you can in everyday conversation. 

This is what the pressure does to you, and everyone. 

So, you need your speaking to be at IELTS 7.5, in order to perform at IELTS 7 level in the exam.

Frequently Asked Questions

Vocabulary often stands out as the key differentiator between candidates scoring at Band 6, Band 7, Band 8, or even Band 9. Learning vocabulary effectively can bring the fastest improvements in your speaking performance—if approached correctly.

It’s much more effective to learn vocabulary in context and focus on phrases, not isolated words. This includes collocations and chunked expressions—like “black tea,” “milky tea,” or “to pour a cup of tea”—so you understand how words naturally fit together.

  • Passive vocabulary refers to words you recognize when reading or listening. To improve it, immerse yourself in extensive reading (magazines, blogs, novels) and listening (podcasts, videos, conversations).
  • Active vocabulary includes words you can confidently use when speaking. To activate this, record and replay new phrases, practice repeating them, create sentences, and apply them in conversations or simulated IELTS responses.
  • Ozdic.com is excellent for discovering collocations.
  • Vocaroo.com allows you to record your voice and listen back for self-assessment.
  • Synonym.com is handy when searching for synonyms to avoid repetition and enrich your language.

    1. Trying speaking really slowly when you practice, then speaking at a natural speed. Finally, try speaking quickly. In your practice, try switching between these modes. See if that helps.

    1. Hi Rachida, thanks for your comment. I don’t think I have a live lesson on binomials. Good suggestion for the future though!

    1. Sure, first of all, be patient. Many people take 2 years to move up 2 bands. Secondly, make a study plan or follow a course to improve your overall level of English. Third, make study and practice of English a daily habit. Fourth enjoy your study – find materials that you like and that interest you. Finally, spend a month or so before your test focussing on exam technique. There are lots of materials on this website that can help you. Go and explore. Best wishes and good luck!
