Quick answer

How do I improve my IELTS vocabulary?

Learn words in groups by topic and always with the words they naturally go with, such as "tackle a problem" or "a sharp rise". Examiners reward accurate, natural use over rare words. Aim for ten useful collocations a week that you actually use in your writing and speaking practice.

1Accuracy beats rarity

Students often swap a simple word for a fancy synonym from a thesaurus and get it slightly wrong. "Children should be educated about nutrition" works. "Children should be enlightened about nutrition" sounds odd. If you are not sure how a word is used, use the simpler one.

2How to make new words stick

  • Write each word in your own sentence, not just a definition.
  • Use it in your next essay or speaking practice within a few days.
  • Review the list every week and cross out words you now use comfortably.
