IELTS Writing Vocabulary by Topic: Word Banks with Model Sentences

Task 2 vocabulary is not generic. "Important," "good," and "big" work on any topic — but they score Band 5. To reach Band 7+, you need topic-specific words used in natural collocations.

Here are Band 7+ word banks for the 8 most common themes, each with model sentences showing the words in context. Learn 10-15 words per theme, focusing on how they combine with other words, not just what they mean.

How to Learn This Vocabulary

Learn 10-15 words per theme. Depth beats breadth.

How to Turn Vocabulary Into Band 7

Step 1 — Pick 10 words per theme. Choose the ones that fit your natural writing style.

Step 2 — Write model paragraphs. For each theme, write one body paragraph using 3-4 of the words. Example:

"The rise of obesity is a pressing public health concern driven by sedentary lifestyles and the cheap availability of processed food. Governments can tackle this by taxing sugar-sweetened beverages and investing in preventive healthcare, as Mexico's consumption data demonstrates."

Step 3 — Get feedback. Write a full essay with the vocabulary and get AI feedback on all four criteria — the Lexical Resource score tells you if the words are working.

Step 4 — Reuse across essays. These collocations transfer. "Mitigate" appears in environment, technology, and crime essays. A small, well-learned bank covers the whole exam.

Frequently Asked Questions

What vocabulary do I need for IELTS Writing Task 2?

You need topic-specific vocabulary plus academic linking language. The 12 Task 2 themes each have their own word banks — Education, Technology, Environment, Health, and so on. Learn 10-15 words per theme with collocations, not isolated words.

How many words should I learn for IELTS Writing?

Learn roughly 10-15 words per theme for the 8 most common themes (about 80-120 words total). More important than quantity is accuracy — using 10 words correctly beats using 30 incorrectly. Collocations matter more than single words.

Does using advanced vocabulary guarantee a high band score?

No. Vocabulary is 25% of the score, and accuracy counts as much as range. A Band 9 essay uses a wide range precisely; a Band 6 essay uses big words incorrectly. Learning collocations and natural usage is better than memorizing long word lists.

What are collocations in IELTS writing?

Collocations are word pairs that naturally go together: make a decision, take responsibility, pose a challenge, gain a competitive edge. Using them correctly signals native-like fluency and boosts your Lexical Resource score.

Should I use different vocabulary for Task 1 and Task 2?

Yes. Task 1 uses descriptive language (increased sharply, fluctuated, a significant proportion). Task 2 uses argumentative and abstract language (arguably, a contributing factor, outweigh). The word banks here focus on Task 2 themes.

How do I avoid sounding like I memorized vocabulary?

Use words you can deploy naturally in context. Memorized vocabulary is obvious when it appears in the wrong collocation ("big problem" as "colossal issue" everywhere). Learn words with their partners and use them in practice essays until they feel natural.
