IELTS Vocabulary for Speaking: Words That Get You Band 7+

At Band 7, examiners expect you to use "less common" vocabulary with "some awareness of style and collocation." This guide gives you exactly what words to learn and how to use them naturally.

The Upgrade Principle

Don't learn random words. Instead, take the basic words you already use and upgrade them:

Band 5-6	Band 7+	Context
good	remarkable, outstanding, beneficial	"It was a remarkable experience"
bad	detrimental, concerning, problematic	"This could be detrimental to health"
very big	substantial, considerable, significant	"A substantial number of people"
very important	crucial, essential, paramount	"Education is essential for development"
a lot of	a considerable amount of, numerous	"Numerous studies have shown..."
get better	improve, enhance, progress	"My skills have improved significantly"
think	believe, consider, reckon	"I firmly believe that..."
like	appreciate, be fond of, value	"I really appreciate good design"

Collocations: Sound Natural

Wrong	Correct Collocation
do a mistake	make a mistake
do progress	make progress
big traffic	heavy traffic
strong rain	heavy rain
open the light	turn on the light
fast food (= drive-thru)	quick meal (= eaten quickly)

How to Learn Vocabulary Effectively

1. Learn in context — Don't memorize word lists. Learn words from articles, podcasts, and real conversations.
2. Learn collocations, not single words — "Heavy rain" is more useful than just "heavy".
3. Use new words immediately — If you learn "detrimental", use it in a practice session the same day.
4. Focus on 5 words per day — Quality over quantity. 5 words used correctly > 50 words forgotten.
5. Review weekly — Use a simple notebook. Write the word, a sample sentence, and review every Sunday.
