Lexical Upgrades
Common to academic substitutions without forced vocabulary
Topic & Why It Matters
Lexical Resource is one of the four IELTS Writing criteria. It measures how accurately and flexibly you use vocabulary, including topic words, collocation, paraphrase, word form, and spelling. Strong vocabulary helps both Task 1 and Task 2 because it lets you report, explain, compare, and evaluate ideas without repeating the same basic words.
Candidates lose marks when they treat vocabulary as decoration. The goal is not to sound impressive; the goal is to sound exact. A clear phrase such as "reduce congestion" is usually better than a dramatic phrase that does not fit the sentence.
Knowledge Points
Structure Template
Upgrade vocabulary as part of the writing process, not as a last-minute layer of difficult words. Use this sequence for both Task 1 and Task 2.
| Stage | Upgrade Focus | What to Do |
|---|---|---|
| Question analysis | Build a topic word bank | Underline the topic nouns and verbs. Add 5-8 precise related terms before planning the essay, so your vocabulary grows from the question rather than from memorised lists. |
| Introduction | Paraphrase safely | Change sentence structure first, then replace only the words you can replace accurately. Keep technical terms if there is no natural synonym. |
| Body paragraphs | Use precise claims and collocations | Upgrade broad words such as 'good', 'bad', 'big', and 'important' into specific effects: 'cost-effective', 'harmful', 'substantial', 'essential', or 'long-term'. |
| Final edit | Remove forced vocabulary | Check every upgraded phrase. If it makes the sentence less natural, less accurate, or more dramatic than intended, replace it with a simpler expression. |
Three-Question Upgrade Audit
| Question | Action |
|---|---|
| Is the word exact? | Check whether the replacement keeps the same meaning, scale, and tone as the original idea. |
| Does it collocate naturally? | Test the word partnership: 'pose a risk', 'reduce emissions', 'provide access', 'meet demand'. |
| Does the paragraph still sound controlled? | Remove emotional, extreme, or showy vocabulary if it makes the claim less credible. |
Vocabulary & Grammar Toolkit
| Common Word - Upgrade Options | Usage Note |
|---|---|
| people -> individuals / residents / employees / consumers | Choose the noun that matches the group in the prompt |
| children -> pupils / young people / teenagers | Use 'pupils' for school context and 'teenagers' for age-specific claims |
| old people -> older adults / elderly residents | More respectful and precise than 'old people' |
| big -> significant / substantial / large-scale | Use 'significant' for effect, 'substantial' for amount, and 'large-scale' for scope |
| small -> limited / minor / modest | Useful for controlled claims and Task 1 changes |
| good -> beneficial / effective / practical | Name the type of positive value instead of using a general adjective |
| bad -> harmful / ineffective / problematic | Select according to damage, weak results, or difficulty |
| important -> essential / central / a major factor | Avoid repeating 'important' in every paragraph |
| many -> a large proportion of / numerous / widespread | Use only when the claim is genuinely broad |
| get -> obtain / receive / gain access to | Choose by meaning: objects, services, or opportunities |
| give -> provide / offer / allocate | 'Allocate' is strong for money, time, or resources |
| help -> support / enable / facilitate | 'Enable' means make possible; 'facilitate' means make easier |
| make -> create / cause / generate / lead to | Pick the causal relationship carefully |
| show -> indicate / suggest / demonstrate | 'Suggest' is cautious; 'demonstrate' is stronger |
| deal with -> address / tackle / manage | 'Address' is formal and safe for problems |
| spend money on -> invest in / fund / subsidise | 'Subsidise' means financially support to reduce cost |
| use -> rely on / make use of / consume | Match the topic: transport, technology, energy, or goods |
| change -> shift / transform / adjust | 'Transform' is a major change; 'adjust' is smaller |
| because of -> due to / as a result of / owing to | Use before noun phrases, not full clauses |
| more and more -> increasingly | Concise and academic, but do not overuse it |
| a lot of problems -> a range of challenges | A common upgrade for problem-solution essays |
| very -> highly / particularly / considerably | Use with compatible adjectives: 'highly skilled', 'particularly useful' |
| thing -> factor / issue / measure / feature | Replace vague nouns with the exact category |
| in the future -> in the long term / over time | More precise time framing |
Common Pitfalls
| Mistake | Correction |
|---|---|
| Using synonyms that change the meaning | Do not change 'children' to 'offspring' or 'government' to 'authority' in every context. Choose words that keep the same meaning and sound natural in IELTS writing. |
| Overusing memorised advanced words | Words such as 'plethora', 'myriad', and 'ameliorate' often sound unnatural in Task 2 essays. Use clear academic vocabulary that fits the sentence. |
| Creating collocation errors | Weak: 'make a policy to solve pollution strongly.' Strong: 'introduce a policy to reduce pollution significantly.' Learn word partnerships, not single words only. |
| Replacing necessary repetition with vague references | If the essay is about public transport, repeating 'public transport' is better than writing 'this aspect' or 'the aforementioned facility' repeatedly. |
| Upgrading every sentence | Lexical range should support clarity. A paragraph with one or two accurate topic phrases is stronger than a paragraph overloaded with forced synonyms. |
Practice Prompt
Set a 40-minute timer. Before writing, create a small word bank for transport, money, access, and city problems. Use only vocabulary you can control accurately.
You should spend about 40 minutes on this task.
Some people believe that public transport should be free for everyone in large cities.
To what extent do you agree or disagree?
Write at least 250 words.

Many cities are considering whether public money should be used to make public transport free for all residents. Although this policy may appear expensive at first, I believe it is a worthwhile investment in large urban areas because it can reduce congestion and widen access to work, education, and essential services.
The clearest benefit is that free buses, trams, and metro systems can encourage residents to rely less on private cars. When fares are removed, short daily journeys become cheaper and more convenient, especially for commuters who currently drive because tickets are costly or complicated. This shift can reduce traffic pressure, lower emissions, and make limited road space more efficient. In this sense, fare-free transport is not simply a social benefit; it is also a practical way to manage urban mobility.
Another important advantage is improved access for low-income groups. Transport costs can prevent people from attending college, accepting work far from home, or reaching healthcare appointments regularly. If these journeys are subsidised by the city, residents have more realistic opportunities to participate in economic and public life. This matters because a transport system should connect people to services, not exclude them through price barriers. Over time, wider access can reduce inequality and support a more productive workforce.
However, free transport should be introduced only where the system has enough capacity and reliable funding. Without additional vehicles, staff, and maintenance, higher passenger numbers could lead to overcrowding and declining service quality. Therefore, I support fare-free public transport in major cities, provided that governments invest in the network itself rather than merely removing ticket prices.
