With a high IELTS score, the doors to the top universities open for you. Most of the top universities across the world have a requirement of a minimum 6.5 or 7 band score in the IELTS exam.

So, improving vocabulary is essential to get a high score, and to improve it, you must practice vocabulary from the best IELTS vocabulary books. 

The books I will mention below will provide you with the best vocabulary you can use in the writing and speaking sections of the IELTS exam.

Vocabulary For IELTS

In the IELTS exam, there is no specific module to check vocabulary. Vocabulary is useful in every section of the IELTS exam. If you use vocabulary right, you can get a high score in the IELTS exam, but using it wrong can also deduct your band score.

Vocabulary is nothing but a synonym for a simple or common word that you already know. 

Most students do not give much attention to vocabulary and thus do not give a thought to IELTS vocabulary books, but to score 8+ bands in the exam, you need to have a good reference book for vocabulary. Thus, you must identify a good vocabulary book and follow it during your preparation. 

  • Ameliorate
  • Apathy
  • Articulate
  • Assuage
  • Beguile
  • Cacophony
  • Capricious
  • Circumspect
