Using a strong vocabulary is crucial for a high IELTS score, but misusing words can hurt your band score. Here are the most frequent IELTS vocabulary mistakes test-takers make, along with tips to correct them and impress examiners.

1. Overusing Advanced or Rare Words: Use formal but natural academic words. Don't force complex words just to sound advanced—clarity is more important than complexity.

2. Misusing Idioms and Informal Expressions: Avoid idioms in formal writing tasks. Use them sparingly in the Speaking test, only when they sound natural.

3. Lack of Context or Incorrect Collocations: Learn word combinations (collocations), not just individual words. Practice phrases like “make a decision,” “raise awareness,” or “take responsibility.”

4. Repetition of Simple Vocabulary: Use synonyms and topic-specific words. Instead of “good,” say “beneficial,” “effective,” or “advantageous,” depending on context.

5. Incorrect Word Forms: Focus on noun, verb, adjective, and adverb forms. Keep a vocabulary journal with word families.

6. Memorising and Repeating Model Answers: Practice using new vocabulary in your own sentences and ideas. Personalise your answers to sound genuine and fluent.

7. Ignoring Register (Formal vs Informal Language): Match your vocabulary to the tone of the task. Use formal, academic words for writing and maintain a natural tone for speaking.
