IELTS Vocabulary List for Band 7 and Above

Key Takeaways

IELTS vocabulary for band 7+, organised by the function each word performs in Writing and Speaking rather than by topic, with examples in test use.

Lexical resource is marked on range and precision, not on rarity. A candidate who uses “considerable” correctly scores better than one who reaches for “prodigious” and misses. This is why topic word lists tend to disappoint: they give you nouns for essays about the environment, when what raises the band is the language of hedging, causation, concession and degree.

The list below is organised by what each word does. Learn the function, and the word transfers to any topic.

Key Takeaways

Lexical resource marks range and precision, not obscurity — a rare word used wrongly lowers the score.
Function-based vocabulary transfers across topics; topic-based vocabulary does not.
Hedging, concession and causation language is what separates band 6 from band 7 in both Writing and Speaking.
Paraphrasing ability is explicitly part of lexical resource, so learn synonym sets, not single words.
Collocation errors are marked under lexical resource, so learn each word with its partners.

Paraphrase sets you will need in every essay

Lexical resource includes paraphrasing. These are the words IELTS prompts use most, with alternatives.

Prompt word	Alternatives
important	significant, crucial, central, pivotal, of consequence
increase (verb)	rise, grow, climb, expand, escalate
problem	issue, difficulty, challenge, drawback, obstacle
solution	remedy, measure, response, intervention, approach
cause (verb)	lead to, give rise to, bring about, trigger, prompt
people	individuals, residents, citizens, the public, communities
children	young people, minors, the young, school-age children
government	the authorities, policymakers, the state, public bodies
money	funding, resources, public spending, investment
think (verb)	believe, maintain, contend, hold the view, argue
good	beneficial, advantageous, valuable, constructive
bad	detrimental, damaging, harmful, adverse
a lot of	a substantial number of, a significant proportion of, the bulk of
nowadays	in recent decades, at present, increasingly

Rotate within a set rather than repeating one word. Repeating “important” six times in an essay is a range problem; using it once and “significant” once is not.

Words to use with care

Word	Problem	Instead
plethora	Almost always used wrongly and marks you as a list-learner	a great many, a wide range of
myriad	Overused in IELTS answers; often mis-constructed	numerous, a wide variety of
utilise	Adds nothing to “use”	use, employ, draw on
detrimental to	Fine, but overused as a fixed phrase	damaging to, harmful to, works against
in a nutshell	Informal register for academic writing	in short, to summarise
Last but not least	Formulaic; examiners see it constantly	A final consideration is…
It is a double-edged sword	A memorised idiom, and rarely precise	There is a trade-off between…

Idioms are credited in Speaking when they are natural and accurate. In Writing they are usually a register mismatch, and a memorised idiom in either skill is audible as a memorised idiom.

A four-week learning schedule

Week	Functions	Daily task	Weekend check
1	Hedging, conceding	10 words; write one sentence each on a Task 2 theme	Write two Task 2 introductions using five of them
2	Cause, degree	10 words; use five in a spoken Part 3 answer	Write one full body paragraph
3	Change, evaluating	10 words; describe a chart aloud using the change set	Write a Task 1 answer using only this week’s words
4	Society, paraphrase sets	Paraphrase five prompts from memory	Full timed Task 2 and mark your own repetition

Marking your own repetition is the useful step. Count how many times you used your five favourite words; that count is what lexical range measures.

FAQ

How much vocabulary do I need for IELTS band 7?

Range and precision matter more than volume. Band 7 lexical resource describes a candidate who uses a sufficient range flexibly, with some awareness of style and collocation and occasional inaccuracy. That is achievable with a few hundred well-controlled words used precisely, and not achievable with thousands used approximately.

Does using rare words raise my IELTS score?

Not by itself. Lexical resource marks appropriacy and precision alongside range, so a rare word used incorrectly lowers the score while a common word used exactly does not. The words that reliably raise the band are the functional ones — hedging, concession and causation.

Should I learn topic vocabulary or general vocabulary?

Function-based vocabulary first, because it transfers to every topic. Topic nouns are worth adding for the recurring Task 2 themes, but they cannot be deployed until you have the language to make an argument with them.

Are idioms good for IELTS?

In Speaking, natural and accurate idiomatic language is credited. In Writing they usually clash with academic register. In both skills a memorised idiom inserted to display range is recognisable and does not help.

Why is my vocabulary score lower than I expected?

Most often repetition and collocation. Using one favourite word six times reads as limited range regardless of how good the word is, and a wrong partner word — “make a research”, “do a mistake” — is marked under lexical resource rather than grammar.

How do I show paraphrasing ability?

Rewrite the prompt in your introduction using different words and a different structure, then vary your key terms through the essay instead of repeating them. Paraphrasing is part of what lexical resource assesses, which is why the paraphrase sets on this page matter more than the rare words do.
