FAQ:IELTS Writing Vocabulary List: 500+ Useful Words for Essays

What is the IELTS Writing vocabulary list and how should I use it?

The IELTS Writing vocabulary list is a curated selection of academic words, cohesive devices, collocations, topic phrases, and task-specific expressions that help you write clearly and precisely. Use it to plan essays, paraphrase the prompt, and vary your word choice. Do not memorize long sentences; instead, learn word families (e.g., analyze, analysis, analytical) and collocations (e.g., pose a threat, reach a consensus, implement a policy), then apply them in your own arguments.

How many new words should I aim to learn for Band 7–9?

Quality matters more than quantity. A practical goal is 15–25 high-utility items per week, mastered for meaning, collocations, and usage. By exam time, a confident command of 300–600 academic items and topic phrases—used accurately—can support Band 7+, while precision, range, and flexibility push you toward Band 8–9.

What counts as “lexical resource” in the band descriptors?

Examiners evaluate range (varied vocabulary), precision (exact meaning), accuracy (correct form/spelling), and appropriacy (register and tone). They also reward natural paraphrasing and effective collocations. Repetition of basic words (e.g., good, bad, a lot) or misused advanced words lowers the score.

Which categories of words give the biggest score impact?

Four categories consistently lift your writing:

• Cohesive devices for logical flow (e.g., moreover, nevertheless, consequently).
• Argument verbs for analytical tone (e.g., contend, demonstrate, undermine).
• Nominalizations to condense ideas (e.g., regulation, inequality, implementation).
• Topic lexis for common themes (education, environment, health, technology, economy, society).

How can I avoid sounding memorized or formulaic?

Use short, adaptable building blocks instead of template sentences. For example, prepare 5–8 versatile sentence starters (There is substantial evidence that…; It is widely maintained that…) and rotate them. Vary cohesive devices naturally, and limit each to once every few sentences. Ensure every “advanced” word fits your exact meaning.

What are high-impact synonyms for common basics?

• important → crucial, pivotal, of paramount importance, consequential
• many → numerous, a considerable number of, a significant proportion of
• cause → provoke, precipitate, give rise to, contribute to
• help → facilitate, foster, promote, expedite
• problem → challenge, dilemma, drawback, adverse effect
• solution → remedy, intervention, policy measure, feasible approach

Which collocations should I prioritize for essays?

Focus on academic pairs frequently used in argumentation:

• pose a risk / threat; mitigate the impact; address a shortage
• enforce regulations; implement reforms; allocate resources
• reach a consensus; challenge an assumption; present evidence
• economic downturn; technological disruption; environmental degradation

How do I paraphrase the question without changing the meaning?

Replace key nouns with precise synonyms, shift grammar (verb → noun), and reframe with broader terms. Example: “Should governments invest more in public transport?” → “To what extent should public authorities increase funding for mass transit systems?” Keep the core topic (investment + public transport) intact.

What vocabulary helps structure a high-scoring introduction?

Use a neutral opener and a clear stance:

• Neutral framing: It is widely acknowledged that… / Recent years have witnessed…
• Scope/contrast: While opponents contend that…, advocates maintain…
• Position: This essay argues that… / This essay will demonstrate that…

What verbs signal strong, analytical argumentation?

Adopt precise reporting and evaluation verbs: contend, assert, maintain, demonstrate, corroborate, invalidate, undermine, exacerbate, prioritize, reconcile, perpetuate. Example: “Subsidies may inadvertently perpetuate inefficiencies while failing to address underlying constraints.”

How do I balance hedging and confidence in my vocabulary?

Use boosters when evidence is clear (clearly, undoubtedly, compellingly) and hedges when generalizing (tend to, may, arguably, to a large extent). Over-hedging weakens your stance; over-boosting sounds dogmatic. Aim for a 70:30 balance favoring precise, cautiously confident claims.

What are examples of topic vocabulary for Education, Environment, and Technology?

• Education: curriculum design, pedagogical approach, vocational pathway, equity of access, attainment gap
• Environment: biodiversity loss, carbon-intensive industries, circular economy, conservation efforts, climate resilience
• Technology: automation, data privacy, digital divide, algorithmic bias, technological diffusion

Which words help with problem–solution and cause–effect essays?

Problem–solution: pressing challenge, root cause, multifaceted intervention, cost-effective measure, scalable policy. Cause–effect: precipitate, stem from, give rise to, compound, culminate in. Example: “Urban sprawl often stems from inadequate planning and culminates in congestion and habitat loss.”

How can I avoid overusing cohesive devices like “moreover” or “however”?

Rotate with subtle alternatives and use punctuation for contrast. Options include additionally, in addition, nonetheless, that said, even so. Use a maximum of one explicit linker per two or three sentences; elsewhere, rely on pronoun reference, parallel structure, and topic sentences for cohesion.

What vocabulary mistakes lower scores?

• Using advanced words inaccurately (e.g., pervasive when you mean persuasive).
• Mixing informal slang with academic tone (e.g., kids instead of children in formal essays).
• Redundant pairs (absolutely essential is often fine; completely unanimous is illogical).
• Over-nominalizing until readability suffers.

How should I practice vocabulary for real exam conditions?

1. Select a recent IELTS topic and draft a 10-sentence paragraph using five target items.
2. Rewrite the paragraph replacing repeated words with precise synonyms or collocations.
3. Underline every cohesive device and remove any that are unnecessary.
4. Time yourself for 10–15 minutes to simulate task pressure.

Can I use idioms or phrasal verbs in formal writing?

Use neutral, academic alternatives. Idioms (a double-edged sword) are risky and can sound informal. Some phrasal verbs are acceptable if concise and precise (carry out research, set up a scheme), but single-word equivalents often read more formally (conduct, establish).

How do I show range without sacrificing clarity?

Pair one advanced item with simple, direct prose. Example: “The policy is untenable because it ignores implementation costs.” Avoid strings of rare words. Aim for one high-value term per sentence and ensure every term is idiomatic in context.

What spelling and word-form issues should I watch for?

Common risks include UK vs. US spelling (programme/program, labour/labor), incorrect derivatives (economical vs. economic), and pluralization (phenomena plural; criterion singular). Maintain consistency and proofread for suffix errors (-tion, -sion, -ity, -ence).

Which verbs help evaluate evidence and counterarguments?

Use verbs that weigh and compare: substantiate, corroborate, refute, qualify, reconcile, juxtapose, prioritize. Example: “While the data corroborate short-term gains, long-term risks remain insufficiently addressed.”

What are strong conclusion phrases that avoid clichés?

Avoid “In a nutshell.” Prefer concise wrap-ups: Overall, the evidence indicates…; On balance, the benefits outweigh the drawbacks provided that…; Ultimately, sustained investment and transparent oversight are indispensable.

Can I recycle vocabulary across different topics?

Yes—many academic verbs and structures transfer well. For instance, allocate resources, enforce compliance, escalate costs, long-term externalities appear in education, health, and environment essays alike. Build a portable core set plus add topic-specific layers.

How do I quickly upgrade basic sentences using better vocabulary?

Transform verbs and add specificity. Basic: “Many people think social media is bad for students.” Upgraded: “A substantial proportion of stakeholders contend that intensive social media use undermines students’ attention and exacerbates procrastination.”

What practice routine will steadily improve my lexical resource?

Adopt a three-step cycle: (1) Collect 10–15 items from model essays and reputable sources; (2) Use them in a timed paragraph and a full essay within 48 hours; (3) Review for accuracy and collocation with a checklist (register, precision, repetition). Repeat weekly and rotate topics to extend coverage.

What sample “mini-bank” of 40 versatile items should I master first?

moreover, nevertheless, consequently, in contrast, contend, demonstrate, undermine, exacerbate, mitigate, allocate, implement, prioritize, equitable, viable, pivotal, detrimental, robust, sustainable, compelling, nuanced, consensus, framework, incentive, constraint, intervention, compliance, transparency, innovation, infrastructure, externality, resilience, accessibility, inclusivity, scalability, accountability, empirical, longitudinal, prevalence, trajectory

Final tip: how do I stay natural on test day?

Plan with simple notes (argument + evidence + example), then choose a few high-value items that fit naturally. If a word feels forced, drop it. Clear ideas expressed with accurate, moderate sophistication beat clumsy “advanced” wording every time.
