IELTS Academic Word List: 150 High-Score Words by Topic (2026)
150 IELTS academic words organised by the 10 most-tested topics — environment, technology, education, health and more — each with collocations, example sentences, and speaking/writing usage notes.

Forget memorising 570 disconnected words. IELTS recycles the same ~10 topics across Task 2, Speaking Part 3, and Reading passages. Master the core vocabulary of those topics — with collocations, not isolated words — and Lexical Resource takes care of itself.
How to use this list: one topic per study session. For each word, note its partners (shown in brackets), say the example aloud, then reuse the word in one written and one spoken sentence within 48 hours.

Jump to How to Actually Retain ThemHow to Actually Retain Them
- Collocations, not words. Never learn "mitigate" alone — learn "mitigate damage/risks." Examiners score the partnership.
- One topic per week. 15 words × 10 weeks beats 150 words in a weekend.
- Produce within 48 hours. Each word must appear in one Task 2 paragraph and one spoken answer or it evaporates.
- Paraphrase-pairs. Learn each word with its plain synonym ("mitigate = reduce") so you can flex in paraphrasing and synonym upgrades.
- Ban the fancy-word essay. One topic word per sentence maximum. Density of rare words with errors reads as Band 6; sparse precise words read as Band 8.
Extend topic-by-topic with our writing vocabulary banks and collocation drills in the collocations guide.
