100 Essential IELTS Vocabulary Words for Band 7+ (With Examples)

If you want to reach Band 7 or higher in IELTS Writing or Speaking, vocabulary matters — but not just any vocabulary. Examiners are looking for lexical resource: words used naturally, accurately, and appropriately for the topic. Repeating “good,” “bad,” and “important” throughout your essay won’t get you far.

This list gives you 100 high-value words and phrases, organized by the topics that appear most often in IELTS Writing Task 2 and Speaking. For each word, you’ll find a simple definition and an example sentence showing how to use it naturally — not just memorize it.

Tip: Don’t try to learn all 100 at once. Pick 10–15 per week, use them in practice sentences, and try to include a few naturally in your next practice essay or speaking session.

How to Actually Use This List (Not Just Read It)

Memorizing definitions won’t raise your score — using words naturally and correctly will. Here’s how to make this list work for you:

• Write your own example sentence for each new word instead of just copying the ones above.
• Group words by essay topic (environment, education, technology, etc.) so you can recall them quickly when a related question appears.
• Practice using 5–6 of these words in a single essay rather than forcing all of them in — natural use matters more than quantity.
• Say new words out loud during speaking practice. Vocabulary used in Speaking should sound conversational, not memorized or robotic.
• Avoid overusing “big” words. Band 7+ isn’t about using the most complex vocabulary — it’s about using the right word accurately and naturally.
