Essential IELTS Writing Vocabulary for Band 7+ (With Examples)

Vocabulary is one of four equally weighted criteria in IELTS Writing, accounting for 25% of your total score. The difference between and often comes down to whether you can move beyond basic, everyday words and use a range of academic vocabulary accurately and naturally.

This guide organises essential IELTS Writing vocabulary by function, giving you ready-to-use words and phrases for every type of essay and Task 1 report.

What Examiners Look For

The Lexical Resource criterion rewards:

1. Range — Using a variety of words rather than repeating the same ones
2. Accuracy — Using words with the correct meaning and in the right context
3. Appropriacy — Using formal, academic vocabulary rather than informal language
4. Less common vocabulary — Demonstrating knowledge of words beyond the most basic level
5. Collocations — Using natural word combinations (not "do a crime" but "commit a crime")

How to Build Your Vocabulary Effectively

1. Read academic texts — Exposure to academic vocabulary in context is the fastest way to learn it naturally
2. Keep a vocabulary notebook — Record new words with their definitions, collocations, and example sentences
3. Practice in writing — Use CambPrep's writing practice to write essays using your new vocabulary and get feedback on whether you are using it correctly
4. Review your errors — When AI feedback highlights vocabulary issues, make a note and address them in your next essay
5. Test yourself regularly — Take a level test to assess whether your vocabulary improvements are translating into higher scores

The key to vocabulary improvement is not knowing more words passively — it is using a wider range of words accurately in your writing. Focus on quality over quantity.

Frequently Asked Questions

How many "advanced" words do I need for Band 7?

There is no specific number, but you should aim to use less common vocabulary naturally throughout your response. This means approximately 10-15 instances of Band 7+ vocabulary across a 250-word essay. The key word is "naturally" — forced or inaccurate usage will not help.

Is it better to use big words or simple words?

Use the most precise word for your meaning, regardless of its complexity. "Effective" is often better than "efficacious" because it is more natural. The goal is accuracy and range, not unnecessary complexity.

Can I use idioms in IELTS Writing?

Generally, avoid idioms in academic writing. Phrases like "at the end of the day" or "the ball is in their court" are too informal for IELTS Writing. However, some semi-formal expressions like "tip of the iceberg" can work if used sparingly and appropriately.

Should I memorise vocabulary lists?

Memorising lists passively is ineffective. Instead, learn words in context through reading and practice. When you encounter a useful word, write an example sentence using it. Active engagement with vocabulary is far more likely to stick than rote memorisation.
