IELTS Vocabulary Strategy: Academic + General Training
IELTS rewards range over rarity. Here is which vocabulary actually moves your band score — and how to study it in 6 focused weeks.

A frequent IELTS myth: "use big words to score 8+". Wrong. The IELTS Writing band descriptors specifically reward lexical range used accurately — five well-deployed B2 words beat one misused C2 word.
What IELTS actually tests
- Reading: high-frequency academic vocabulary + paraphrasing
- Listening: everyday vocabulary + a handful of academic terms
- Writing: lexical range, collocation, accurate use
- Speaking: natural collocations, topic-specific vocab, idiomatic expressions used appropriately
In short: not the hardest words, but the right words.
High-leverage word categories
- Paraphrasing verbs — increase / rise / surge / climb / soar. IELTS tests whether you can avoid repeating the prompt verbatim.
- Topic vocabulary for the 8-10 common Writing Task 2 themes (education, environment, technology, urbanisation, health, work, government, media).
- Discourse markers — furthermore, in contrast, in particular, on the other hand.
- Speaking collocations — catch up on, look forward to, get the hang of, run out of time.
A 6-week IELTS plan
- Weeks 1-2: 200 high-frequency academic words (AWL sublists 1-3). 1 example sentence each.
- Week 3: 100 paraphrasing verbs + 50 discourse markers. Practice rewriting paragraphs.
- Week 4: Topic vocabulary for 4 themes (50 words each). Write a Task 2 essay per theme.
- Week 5: Speaking — 60 natural collocations. Record yourself answering Part 2 cue cards.
- Week 6: Mixed practice. 2 full Reading sections + 2 full Writing tasks + 2 Speaking sets.
Mistakes that cost band points
- Memorising essay templates with fancy words you don't really use. Examiners notice.
- Misusing C1/C2 words. Better to be accurate at B2 than wrong at C2.
- Ignoring collocation. "Strong rain" instead of "heavy rain" is exactly the kind of slip that costs you.
Make it stick
Spaced repetition over cramming, every time. If you're not sure where to start, take the free level test — it'll tell you which band of vocabulary to focus on first.
