IELTS Speaking Vocabulary: How to Show Range Without Memorising Scripts

Lexical Resource is 25% of your Speaking score. Here's how to demonstrate vocabulary range naturally — not through scripted phrases.


At Band 7 for Lexical Resource in Speaking, examiners want to see "sufficient range to discuss topics at length and vary formulation." This means avoiding repetition, choosing precise words, and recovering naturally from vocabulary gaps. Here's how to build this without memorising scripts.

The Examiner's Vocabulary Checklist

Examiners listen for:

  • Do you use topic-specific vocabulary appropriately?
  • Do you avoid repeating the same words too often?
  • Can you paraphrase when you don't know an exact word?
  • Do you use collocations naturally (not just isolated vocabulary)?

Technique 1: The Synonym Habit

For any high-frequency word you tend to overuse, prepare 2-3 synonyms. For "important" → significant, crucial, vital. For "increase" → rise, surge, grow, escalate. For "problem" → issue, challenge, concern, drawback. Use these interchangeably when speaking.

Technique 2: Use Collocations, Not Isolated Words

Collocations (words that naturally go together) are more impressive than individual vocabulary items. Compare:

  • ❌ "The environment has a bad effect."
  • ✓ "This has a detrimental impact on the environment."

Key collocations for IELTS Speaking: pose a challenge, raise awareness, tackle an issue, significant impact, growing concern, address a problem, make a contribution.

Technique 3: Paraphrasing When You Lose a Word

Don't freeze when you can't think of a word. Use circumlocution: describe what you mean. "I can't remember the exact word, but it's the kind of situation where..." This is actually evidence of communicative competence — an examiner skill they're looking for.

Topic Vocabulary to Prepare

IELTS Speaking covers predictable topics. Prepare vocabulary clusters for: technology, environment, education, work and career, travel, relationships, health, media and communication. For each topic, know 8-10 relevant collocations and phrases — not just single words.
