Week 3 continues — IELTS Speaking Decoded. Yesterday we broke down Fluency and Coherence. Today: Lexical Resource — the criterion that most directly rewards deliberate vocabulary preparation, and the one where targeted study pays off fastest.
Lexical Resource is scored on four separate sub-criteria
Range
How many different words you use. Band 5 speakers recycle the same 200–300 words. Band 7+ speakers draw from a broader pool and vary their word choices.
Precision
Choosing the most accurate word for the meaning. "Rewarding" is more precise than "good". "Detrimental" more precise than "bad".
Collocation
Natural word pairings that native speakers use. "Make a decision" (correct). "Do a decision" (wrong). Examiners notice both.
Paraphrase
Expressing the same idea in multiple ways without the examiner needing to repeat the question. Signals genuine language ownership.
Can you say the same thing three different ways?
Paraphrase is the clearest signal of lexical range. If you can only express an idea one way, your range is limited regardless of how many individual words you know.
Practice: take any IELTS Part 1 answer and express the same content using three entirely different vocabulary sets. This single exercise builds range, precision, and paraphrase simultaneously.
- Original: "I think technology is very useful for students."
- Version 2: "Digital tools have transformed how young people learn."
- Version 3: "Access to technology has become indispensable in modern education."
5 precise words per topic accelerates range the fastest
The 10 most common IELTS topics are predictable. For each topic, identify 5 words you currently never use and practice deploying them in every answer on that topic this week. Range improves fastest through deliberate expansion, topic by topic.
