How to Use This Vocabulary

Learning vocabulary is not just about memorising definitions. You need to know how to use words in context. Here is a method that works:

Learn words in collocations. Do not just learn “rewarding” — learn “a rewarding career”, “a rewarding experience”, “find something rewarding”. Collocations are words that naturally go together.

Use new words in your speaking practice. After learning a new word, try to use it in your next speaking practice session. The more you use a word, the more natural it will feel.

Do not overuse idioms. Idioms like “double-edged sword” and “off the beaten track” can boost your score, but only if you use them naturally. Using too many idioms sounds forced and unnatural.

Focus on accuracy. It is better to use simple vocabulary correctly than complex vocabulary incorrectly. If you are not sure how to use a word, do not risk it.

With consistent practice, you will build a vocabulary that serves you well in the IELTS Speaking test and beyond. Good luck!
