Advanced IELTS Vocabulary: 400 Words and Phrases (Free PDF)

Advanced IELTS vocabulary means being able to choose precise words, combine them naturally and use them appropriately for the situation. An unfamiliar word is useful only when you understand its meaning, grammar and tone. “Mitigate a problem”, for example, means reduce its harmful effects; it does not mean solve it completely.

This IELTS Worldly guide contains 400 words and phrases, each with a clear meaning, a usage explanation, useful collocations and an original sample sentence. Study by topic, use the alphabetical index to find a word, or download the complete free PDF.

The sample sentences support Band 9 preparation, but individual sentences do not receive IELTS band scores. Use them to understand effective choices, not as lines to memorise. The collection includes advanced vocabulary, useful familiar words with precise uses, and rarer items labelled for recognition.

Start here: learn words you can use accurately

If you are unsure where to begin, select five or six words from this useful starting set: alleviate, allocate, ambiguous, coherent, compensate, comprehensive, conducive, consensus, detrimental, disparity, empirical, equitable, exacerbate, feasible, implication, incentive, mitigate, nuance, pertinent, plausible, resilience, substantial, sustainable, undermine and viable.

Learn the meaning, practise the word combination and then write a sentence connected to your own ideas. For structured support, visit our English for IELTS learning hub.

How to read each vocabulary entry

• Meaning: the sense illustrated in the sample, rather than every possible dictionary meaning.
• Use it accurately: grammar, register or a distinction that helps prevent misuse.
• Useful combinations: collocations and patterns worth learning together.
• Sample sentence: an original example showing how the word contributes to a complete idea.

Register labels are guidance. Neutral vocabulary can fit many situations; formal vocabulary is more typical of professional or academic discussion. Literary, specialised and recognition priority labels identify words to understand when encountered, without forcing them into your own answers. A sentence in a literary entry illustrates the meaning; it is not a recommendation to use that register throughout an IELTS response.

The examples are teaching sentences. Any chart figures are explicitly illustrative. Learn a word’s pronunciation using dictionary audio as well as its written form; our pronunciation basics guide explains how to begin.

What vocabulary contributes to an IELTS score

The official IELTS Writing descriptors reward accurate, appropriate and flexible vocabulary use. High-level performance involves precise meaning and natural control, with very few spelling or word-formation errors. Replacing clear words with obscure alternatives does not demonstrate those abilities by itself.

The Speaking descriptors also emphasise precision, flexibility and idiomatic language. Here, idiomatic language includes natural word combinations; it is not an instruction to insert a memorised proverb into every answer.

Lexical Resource is one of four equally weighted criteria within each Writing task and within Speaking. Listening and Reading use correct-answer scoring rather than a separate vocabulary band. See IELTS scoring in detail. Vocabulary supports all four skills, but it works alongside comprehension, task fulfilment, grammar and other assessed abilities.

How to use advanced vocabulary in each IELTS skill

Writing Task 2: make the relationship between ideas precise

Choose vocabulary after deciding what you want to say. If a policy makes a problem worse, exacerbate may fit. If it reduces harm without removing the problem, mitigate may fit. If two approaches work well together, they may be complementary. These distinctions strengthen an argument more than repeated claims that something is “very important”.

Build a paragraph around a claim, a reason and a relevant explanation. Use our Writing Task 2 language guide and formal vocabulary lesson to practise turning vocabulary into an answer to a specific question.

Academic Writing Task 1: match the word to the data

Describe only what the visual supports. Fluctuate requires movement up and down; plateau requires a period of relative stability; plummet describes a rapid, large fall. A change from 100 to 99 is usually better described as a slight decrease. “Significant” in everyday description should not be confused with a statistical significance test that the visual does not provide.

Use precise measurements where available. Do not invent causes for a trend or replace numbers with dramatic adjectives. A clear comparison is more useful than a rare word.

General Training Writing Task 1: match the relationship

A formal request might say, “I would appreciate clarification of the revised arrangements.” A friendly message might say, “Could you let me know what has changed?” Both can be effective. The relationship with the reader determines whether a word sounds natural.

Practise register with our formal and informal English guide and tone and style lesson. Do not turn every letter into an academic essay.

Speaking: answer naturally before searching for impressive wording

Use vocabulary you can pronounce and retrieve comfortably. “I felt apprehensive at first” can fit an account of starting a new job. “The experience enhanced my autonomous cognitive development” is unlikely to sound natural in the same conversation.

For a more abstract Part 3 answer, words such as equitable, incentive and viable may help you discuss policies or choices. Use our Speaking Part 3 guide to practise explaining reasons rather than reciting prepared sentences.

Reading: recognise meaning, word families and qualifications

Recognising a word does not settle the answer. Check who or what it refers to, whether the writer supports the idea, and whether the claim is certain, tentative or limited. Plausible does not mean proved; sporadic does not mean regular; negligible does not mean zero.

Practise finding those distinctions with our IELTS Reading skills guide. When you meet an unknown word, use the sentence and paragraph to infer a possible meaning, then check it afterwards.

Listening: connect written words with their spoken forms

Learn how a word sounds in a phrase, including stress and weak surrounding words. Record the difference between what you expected to hear and what was actually said. Check spelling and grammatical form when entering an answer, and follow the question’s instructions.

Our IELTS Listening skills guide can help you connect vocabulary study with actual listening practice. Reading a word repeatedly is not the same as recognising it in connected speech.

10 vocabulary models for Band 9 preparation

These short models demonstrate language choices. They are not complete test answers and have not received examiner scores. The annotations explain what to notice rather than assigning a band to a paragraph.

Model 1: Education and equitable access

Sample: “Online courses can improve accessibility, but they do not automatically make education more equitable. Students with reliable devices and a quiet place to study may benefit more than those without either. Institutions should therefore consider the support learners need, rather than assume that making a course available online removes every barrier.”

Why the vocabulary works: Accessibility concerns the ability to use the course; equitable concerns fairness across different circumstances. The paragraph explains the difference instead of treating the words as interchangeable praise.

Model 2: Transport and workable alternatives

Sample: “Higher parking charges may discourage some car journeys, but the policy is unlikely to be effective where public transport is unreliable. A viable alternative requires routes and timetables that fit residents’ daily commitments. Improving those services could alleviate congestion without placing a disproportionate burden on people who have few practical choices.”

Why the vocabulary works: Viable, alleviate and disproportionate each add a distinct meaning. The qualified verbs avoid promising that one policy will solve every transport problem.

Model 3: Technology and evidence

Sample: “The introduction of a new system should be followed by a rigorous evaluation of its effects. Faster processing may be beneficial, but it should not be treated as the only measure of success. The organisation also needs empirical evidence about accuracy, accessibility and the experience of users who require assistance.”

Why the vocabulary works: The paragraph names the criteria that make an evaluation rigorous. Empirical evidence means observed information, rather than an assertion that the writer’s view is obviously correct.

Model 4: Work and employee retention

Sample: “Higher remuneration may help a company attract staff, but retention also depends on everyday working conditions. Employees who face an excessive workload and receive little useful feedback may still look elsewhere. A more comprehensive approach would consider pay, opportunities to develop and whether responsibilities can be completed within reasonable hours.”

Why the vocabulary works: Remuneration identifies payment, retention concerns keeping staff, and comprehensive introduces a wider response. None is used merely to repeat the same idea.

Model 5: Environment and clear claims

Sample: “Environmental claims should be specific enough for customers to assess. Describing packaging as biodegradable, for example, does not explain the conditions required for it to break down. Greater transparency would help people distinguish a genuine improvement from a label that sounds reassuring but provides little practical information.”

Why the vocabulary works: The paragraph explains a limitation without claiming that every product with the label is misleading. Distinguish is followed by a clear comparison.

Model 6: Speaking about a difficult experience

Sample: “I was quite apprehensive when I started the job because I had never used that kind of software before. Fortunately, one of my colleagues was very patient. She let me try each step myself and only stepped in when I needed help. After a few weeks, I felt much more confident and could deal with ordinary problems independently.”

Why the vocabulary works: One precise adjective fits naturally among familiar words. The account develops through specific experience rather than a sequence of elaborate synonyms for nervousness.

Model 7: Speaking about your personality

Sample: “I’m fairly reserved when I meet a large group for the first time, but I wouldn’t say I’m uninterested. I usually listen for a while before joining in. With close friends, I’m much more talkative, especially if we’re discussing something we all care about.”

Why the vocabulary works: Reserved describes outward behaviour without implying a lack of interest. The speaker qualifies the description rather than applying one label to every situation.

Model 8: Speaking Part 3 about public spaces

Sample: “I think shared spaces can help community cohesion, but simply building a park isn’t enough. People need to feel that it is safe, accessible and relevant to their routines. If there are places to sit, activities for different ages and convenient routes into it, residents may have more reasons to spend time there.”

Why the vocabulary works: Community cohesion is explained through practical conditions. The answer uses academic vocabulary without losing the rhythm of natural speech.

Model 9: Academic Task 1 with illustrative figures

Practice data: A service recorded 100 users in January, 140 in February, 180 in March, 180 in April and 181 in May.

Sample: “The number of users rose substantially between January and March, increasing from 100 to 180. It then plateaued at around 180 for the remaining two months, with only a marginal rise in May.”

Why the vocabulary works: Substantially describes the earlier 80-user rise; plateaued allows small variation around the later level. No reason for the change is invented.

Model 10: A professional request with a specific purpose

Sample: “I would appreciate clarification of the revised application procedure. The current instructions are ambiguous about whether existing members need to submit the same documents as new applicants. A short explanation of the requirements would help us provide accurate information and avoid unnecessary delays.”

Why the vocabulary works: Ambiguous identifies the exact problem with the instructions. The request is courteous and practical, with no need for literary vocabulary.

Learn collocations, grammar patterns and word families together

Collocations make vocabulary usable

A collocation is a combination that sounds natural to proficient users: reach a consensus, allocate resources, mitigate risks or a substantial increase. Learning only the headword can leave you unsure about the verb, noun or preposition around it.

For each new entry, keep one combination that serves a topic you discuss. Compare “do a decision” with “make a decision”: a more unusual adjective will not repair the wrong verb. Practise with our collocations lesson and academic collocations guide.

Grammar belongs to the word

• conducive to learning, detrimental to confidence, compatible with a system.
• attribute a result to a cause; distinguish one group from another.
• prohibit someone from doing something; empower someone to act.
• advocate investing, rather than advocate to invest.
• facilitate access, rather than facilitate people to access something.
• evidence, information, advice and legislation are normally uncountable in the relevant general uses: a piece of evidence, some information, a piece of advice, a piece of legislation.

Our countable and uncountable nouns guide helps explain why a sentence can contain the right idea but the wrong noun form.

Ten word families worth practising

• analyse → analysis → analytical: analyse the findings; a careful analysis; an analytical approach.
• assess → assessment: assess the impact; an independent assessment.
• compensate → compensation: compensate customers; offer compensation.
• diverse → diversity → diversify: diverse experiences; cultural diversity; diversify income.
• evaluate → evaluation → evaluative: evaluate a programme; a programme evaluation; evaluative comments.
• exclude → exclusion → exclusive: exclude a group; social exclusion; exclusive access.
• innovate → innovation → innovative: innovate in design; useful innovation; an innovative approach.
• rely → reliable → reliability: rely on a service; reliable transport; service reliability.
• sustain → sustainable → sustainability: sustain an activity; sustainable development; financial sustainability.
• vary → variation → varied → variable: vary the routine; regional variation; varied experience; variable demand.

These are related forms, not freely interchangeable replacements. For example, varied means containing different kinds, whereas variable often means changing or inconsistent. Use our word families lesson to practise choosing the form required by the sentence.

Paraphrase accurately without changing the meaning

Paraphrasing involves expressing the same idea through a suitable combination of vocabulary and structure. It does not require replacing every word. Keep names, technical terms and essential distinctions when changing them would make the statement less precise.

• “The cost makes the course impossible for some students to afford.” → “The fee is prohibitive for some students.” The barrier to participation remains central.
• “The results could have another reasonable explanation.” → “An alternative explanation is plausible.” Plausible still means possible, not established.
• “The service is available, but some people cannot use it.” → “Availability does not guarantee accessibility.” The second sentence makes the distinction explicit.
• “The two methods are different but work well together.” → “The methods are complementary.” This does not mean they are identical.
• “The changes reduce the harm without removing it.” → “The changes mitigate the harm.” Do not replace mitigate with eliminate.
• “The figure changed from 50 to 51.” → “The figure rose slightly.” Plummeted and surged would distort the size or direction of the change.

Use our synonyms and antonyms guide to compare meaning in context. Familiar vocabulary is worth repeating when a proposed synonym would change the claim.

25 advanced vocabulary traps and practical fixes

Trap 1: Treating rare words as automatic high-band language

Fix: Choose the most precise natural expression. “A vague intention” is usually more helpful than “velleity” in ordinary discussion, even though recognising the rarer word may be useful when reading.

Trap 2: Learning a meaning without its grammatical pattern

Fix: Record the surrounding words: conducive to, compatible with, attribute something to a cause. Practise the pattern in a new sentence.

Trap 3: Using stronger certainty than your evidence allows

Fix: Replace inevitable with likely or possible when the outcome is uncertain. A confident tone cannot make limited evidence conclusive.

Trap 4: Confusing a proposed explanation with a finding

Fix: A hypothesis is investigated; empirical findings come from observation. Use tentative or plausible when an explanation remains open to revision.

Trap 5: Using refute when you only mean disagree

Fix: Refute requires evidence or reasoning that shows a claim is wrong. If you only question it, use challenge, dispute or disagree with as appropriate.

Trap 6: Mixing up qualitative and high-quality

Fix: Qualitative concerns descriptions and experiences rather than numerical measures. A qualitative study can be carefully or poorly designed.

Trap 7: Confusing revenue with profit

Fix: Revenue is income from activities such as sales. Profit depends on costs as well. Do not use the words interchangeably in a business example.

Trap 8: Misunderstanding disposable income

Fix: In its standard economic sense, it is income after direct taxes. Money left after all essential expenses is a different measure.

Trap 9: Treating mitigate, alleviate and eliminate as identical

Fix: Mitigate and alleviate generally concern reducing harm or severity. Eliminate means remove. Choose the verb that matches the extent of the change.

Trap 10: Confusing equality with equity

Fix: Equal amounts or treatment do not always address different needs. When using equitable, explain the circumstances that make a distribution fair.

Trap 11: Saying data prove causation when they show association

Fix: Two changes occurring together do not automatically show that one caused the other. Describe the observed relationship and qualify the interpretation.

Trap 12: Using a dramatic trend word for a tiny movement

Fix: A one-unit fall from 100 to 99 is a slight decline in an ordinary chart context. Reserve plummet for a genuinely rapid, large drop.

Trap 13: Confusing similar with identical

Fix: Identical is a stronger claim. Use comparable when the items are similar enough for a useful comparison but differ in other respects.

Trap 14: Confusing discrete with discreet

Fix: Discrete stages are separate stages. A discreet conversation is handled privately or without attracting attention. The spelling difference changes the meaning.

Trap 15: Confusing complementary with complimentary

Fix: Complementary approaches work well together. Complimentary remarks express praise; a complimentary ticket is provided free of charge.

Trap 16: Confusing ambivalent with indifferent

Fix: Ambivalent means having conflicting feelings. Indifferent means not particularly concerned. Someone can care deeply and still be ambivalent.

Trap 17: Choosing a negative word for a positive meaning

Fix: Notorious means known for something undesirable. Use respected, renowned or well known when the intended meaning is positive or neutral.

Trap 18: Making formal writing unnecessarily elaborate

Fix: Begin is often as effective as commence; despite may be clearer than notwithstanding. Formality should help the situation, not obstruct understanding.

Trap 19: Putting slang into an inappropriate setting

Fix: Knackered is very informal British English. Exhausted is a safer choice in a formal letter or essay. Do not learn a regional expression without its register.

Trap 20: Treating every phrasal verb as informal

Fix: Register depends on the expression. Carry out research is suitable in formal writing, while some other phrasal verbs are strongly conversational. Our phrasal verbs guide offers contextual practice.

Trap 21: Using an uncountable noun as an ordinary singular count noun

Fix: Write useful advice or a useful piece of advice, not a useful advice. Check the noun’s meaning in the sentence because some nouns have both countable and uncountable uses.

Trap 22: Confusing a word family with a set of identical meanings

Fix: Check both form and sense. An exclusive service may exclude people; inclusive has the opposite purpose. Related spelling does not guarantee interchangeable meaning.

Trap 23: Learning a word only through its spelling

Fix: Listen to it, notice the stressed syllable and practise it within a phrase. A word you recognise on a page may still be difficult to retrieve or understand in speech.

Trap 24: Translating every phrase word for word

Fix: Check the English combination rather than translating separate words. Learn make a decision, reach a conclusion and raise a concern as complete patterns.

Trap 25: Adding new words without reviewing previous errors

Fix: Keep a short error log with the original sentence, a correction and a new example. Use our error correction lesson and spelling rules guide to target repeated problems.

A practical four-week vocabulary study plan

This is a flexible practice routine, not a guarantee of a particular score or a deadline for mastering 400 entries. Select five or six useful items on a study day and reduce that number if you cannot use them accurately later.

Week 1: Meaning and combinations

Start with argumentation, causes and education. For each word, write a short meaning in your own language or plain English, one useful combination and one original sentence. After closing the page, try to recall the combination without looking.

Week 2: Word forms and paraphrasing

Choose topics such as work, technology and cities. Change a sentence from a verb construction to a noun construction where it remains natural. Compare the versions for meaning, grammar and tone. Do not force a transformation that makes the sentence less clear.

Week 3: Speaking and connected writing

Record a short answer or write a paragraph using two or three items that fit naturally. Listen or read back. Check whether the vocabulary made the message clearer, whether the grammar was accurate and whether your examples answered the question.

Week 4: Review and transfer

Revisit earlier words after a gap and use them in a new topic. Complete the exercises below, then return to the relevant entries for any mistakes. Select a few literary or specialised words for recognition practice without adding them to every speaking answer.

A ten-minute review routine

1. Spend two minutes recalling yesterday’s words without looking.
2. Spend three minutes checking meaning, pronunciation and a useful combination.
3. Spend three minutes producing a new sentence or a short spoken explanation.
4. Spend two minutes recording one correction and choosing the next review date.

Review a difficult item sooner and a familiar one after a longer gap. The goal is reliable recall and flexible use, not a growing list of words you recognise only when the page is open.

20 vocabulary practice questions

Try these without looking back at the entries. The first ten use the word bank once each. The second ten ask you to correct a grammar or meaning problem. Some corrections allow more than one natural answer.

Questions 1–10: choose the appropriate word or phrase

Word bank: ambivalent; conducive; discrete; disposable income; empirical; mitigate; nominal; obsolete; qualitative; refute.

1. The quiet room was _____ to concentrated study.
2. The old system became _____ when its essential software was no longer supported and a replacement took over its function.
3. Interviews about people’s experiences provided _____ information rather than numerical measurements.
4. In the economic definition used here, income remaining after direct taxes is called _____.
5. The claim needs _____ evidence collected through observation or investigation.
6. The club charged a _____ fee intended to remain very small for participants.
7. The training consisted of three _____ stages, each with its own activities.
8. I felt _____ about moving: I welcomed the opportunity but disliked the idea of leaving my family.
9. The temporary arrangement could _____ the disruption, although it would not remove it completely.
10. To _____ the claim, the writer must show that it is wrong rather than merely express disagreement.

Questions 11–20: improve the sentence

11. “The programme will facilitate students to find suitable courses.”
12. “The government introduced a legislation about the reporting process.”
13. “Could you give me an advice about choosing a course?”
14. “Constant interruptions can be detrimental for concentration.”
15. “The committee reached to a consensus after the discussion.”
16. “The researcher was uninterested, so both sides could trust her to judge the dispute fairly.”
17. “The figure plummeted from 100 to 99, a decrease of just one unit.”
18. “The company recorded 10,000 dollars in profit from sales before deducting any costs.”
19. “I am ambivalent about the issue because I have no interest in it and feel neither attracted nor concerned.”
20. “The approaches are complementary, so they cannot be used together.”

Practice answers and explanations

Answers 1–10

1. Conducive: the pattern is conducive to + noun or -ing form.
2. Obsolete: the system has been replaced and is no longer useful for its former function.
3. Qualitative: the information concerns experiences rather than numerical measurement.
4. Disposable income: the definition concerns income after direct taxes, not after every living expense.
5. Empirical: the evidence must come from observation or investigation.
6. Nominal: this sense describes a very small charge.
7. Discrete: the stages are separate and distinguishable; discreet would concern privacy or discretion.
8. Ambivalent: the person has conflicting feelings rather than no feelings about the decision.
9. Mitigate: the arrangement reduces the harmful effect without eliminating it.
10. Refute: the writer must provide a reasoned or evidenced rejection of the claim.

Answers 11–20

11. “The programme will facilitate students’ access to suitable courses.” Alternatively, “The programme will help students find suitable courses.” Facilitate normally takes a noun phrase rather than someone to do something.
12. “The government introduced legislation about the reporting process.” A piece of legislation is another option when referring to one measure.
13. “Could you give me some advice about choosing a course?” Advice is uncountable in this use; a piece of advice is possible when referring to a specific suggestion.
14. “Constant interruptions can be detrimental to concentration.” Learn detrimental to as a complete pattern.
15. “The committee reached a consensus after the discussion.” Reach takes the object directly in this expression.
16. “The researcher was impartial, so both sides could trust her to judge the dispute fairly.” Uninterested means lacking interest; it does not establish fairness. Whether someone is impartial should, in a real argument, be supported rather than merely asserted.
17. “The figure fell slightly from 100 to 99.” The size described does not justify the dramatic verb plummet in an ordinary chart comparison.
18. “The company recorded 10,000 dollars in revenue from sales before deducting any costs.” Profit concerns what remains after the relevant costs are taken into account.
19. “I am indifferent to the issue because I have no particular interest in it.” Ambivalent would fit if the speaker had competing positive and negative feelings.
20. “The approaches are complementary, so they can work well together.” If the intended meaning is that they cannot coexist, use mutually exclusive instead. The correction depends on the meaning you intend to preserve.

Advanced IELTS vocabulary FAQs

1. What is advanced vocabulary for IELTS?

It is vocabulary you can use precisely, naturally and flexibly to express the ideas required by a task. That includes useful academic words, accurate everyday words, collocations and an understanding of register.

2. Are all 400 entries C1 or C2 words?

No. This is an advanced-use study guide, not an official CEFR classification. Some familiar words are included because their meanings, patterns or distinctions are frequently useful. Difficulty can also vary between different senses of the same word.

3. Is there a list of words that guarantees Band 9?

The IELTS descriptors assess how vocabulary is used within a response. They do not award a band for completing this list or inserting particular words. Accuracy, appropriateness and flexibility must be demonstrated in context.

4. Can a single sentence receive Band 9?

A sentence can illustrate strong language choices, but it cannot establish a band for a complete Writing or Speaking performance. The samples here are teaching examples for high-band preparation, not examiner-scored sentences.

5. How many advanced words should I use in an essay?

There is no useful fixed quota. Use the words needed to explain the argument accurately. Forcing an unusual word into every sentence can create repetition, awkwardness or errors instead of demonstrating control.

6. Should I replace every simple word with an advanced synonym?

No. Common words often express the meaning most naturally. Replace a word only when the alternative improves precision, suits the grammar and preserves the intended meaning.

7. Should I learn rare words such as velleity or vanquish?

You may learn to recognise them if they appear in material you read, but they are low priorities for most everyday IELTS output. Their inclusion preserves and explains items from the original page rather than recommending frequent use.

8. What is the difference between active and recognition vocabulary?

Active vocabulary consists of words you can produce accurately when speaking or writing. Recognition vocabulary includes words you understand when reading or listening but may not yet use comfortably yourself.

9. Why does each entry include collocations?

Knowing a meaning does not tell you which surrounding words sound natural. Learning reach a consensus or mitigate risks helps you build an accurate phrase instead of assembling one through word-for-word translation.

10. Do I need to learn all the meanings of every word?

Begin with the sense relevant to your current reading or topic. Add other senses later. For example, credit can refer to borrowing, praise or academic achievement, and the grammar around it may change.

11. How should I learn word families?

Learn related forms in separate short phrases: evaluate a programme, an evaluation of the programme, evaluative feedback. Check the meaning and grammar of each form instead of assuming they can occupy the same place in a sentence.

12. What should I do when two synonyms seem identical?

Compare their register, strength, typical combinations and grammar. Mitigate, reduce and eliminate overlap in some contexts but express different degrees or kinds of change. A learner’s dictionary can help you check the intended sense.

13. Can I use informal vocabulary in Speaking?

Natural conversational vocabulary can fit Speaking, but register still matters. Strong slang or a regional expression is not automatically a good choice. Use language you understand and can handle comfortably in the situation.

14. Do I need idioms to achieve a high Speaking score?

Natural idiomatic language matters, but it is broader than colourful sayings. Familiar combinations and expressions used accurately can be idiomatic. A memorised proverb that does not fit the answer adds little value.

15. Are phrasal verbs unsuitable for formal writing?

Not all of them. Carry out research and point out a limitation can be suitable in formal contexts. Check the particular expression and its meaning instead of treating all multiword verbs as informal.

16. Can I memorise the sample sentences?

You can study their patterns, but practise adapting them to new ideas. Reproducing a sentence without understanding its grammar or relevance can create an unnatural answer that does not address the question.

17. How can I remember vocabulary for longer?

Try recalling it after a gap, use it in a new context and return to mistakes. Keep review manageable. A word you can explain and use next week is more useful than several words you recognise only immediately after reading them.

18. Should I study vocabulary by topic or alphabetically?

Topic study helps you connect ideas and phrases for related tasks. Alphabetical organisation helps you find a particular word quickly. This guide provides topic groups and an index so you can use both approaches.

19. How can vocabulary study help Reading?

It can help you recognise paraphrases, follow relationships and distinguish qualified claims from absolute ones. Still check the passage carefully: understanding a word does not replace understanding the writer’s actual statement.

20. How can vocabulary study help Listening?

Connect meaning with pronunciation and grammatical form. Listen to the word in a phrase, practise recognising it in connected speech and check whether the answer requires a singular, plural or another form.

21. Is spelling important?

Yes. A useful word must be written accurately when the task requires it. Record spellings that you repeatedly confuse, then practise them in meaningful phrases rather than only copying isolated letters.

22. Should I use British or American spelling?

Both standard varieties are accepted in IELTS; see IDP’s British and American English guidance. For clear editing habits, use one variety consistently where possible. Pay attention to distinctions such as British noun licence and verb license, rather than treating every spelling difference as an error.

23. Do I need a British accent to use these words?

No. Focus on being intelligible, using appropriate word stress and speaking with control. The Speaking descriptors assess pronunciation rather than requiring imitation of a particular national accent.

24. Can I use Task 2 vocabulary in Academic Task 1?

Only when it suits the visual and the reporting task. A chart description may need substantial, fluctuate or plateau. Terms such as equitable or detrimental can introduce judgements that the visual does not support.

25. Can I use formal vocabulary in every General Training letter?

No. A letter to a friend and a professional complaint have different relationships with the reader. Choose language that communicates the purpose naturally and keeps the tone appropriate throughout.

26. What should I do if I cannot pronounce a useful word?

Check reliable dictionary audio, break the word into syllables and practise it in a short phrase. If it still disrupts your fluency, use a familiar alternative while continuing to practise the new word separately.

27. What if I am unsure whether a word fits my sentence?

Use a familiar accurate expression in the timed task. During review, check the new word’s meaning, grammar, collocations and register, then write another sentence to test your understanding.

28. Does this page preserve the original vocabulary list?

Yes. All 208 original headwords are retained, with explanations and examples, alongside 192 additional entries. Some original words appear in topic sections; the remaining words are explained in the additional A–Z section.

29. What does the free PDF include?

It includes the complete 400-entry collection, an alphabetical index, ten contextual models, usage guidance, 25 traps and fixes, 20 practice questions with answers, a study plan and these FAQs.

30. How can I tell whether my vocabulary is improving?

Look for fewer recurring errors, more precise explanations and the ability to use a word in an unfamiliar topic. Compare earlier and later work for meaning and control, not just the number of long words.
