Key Takeaways

  • Lexical Resource is 25% of your Task 2 score - vocabulary range and accuracy matter as much as grammar.
  • Learn words with their collocations and example sentences, not in isolation.
  • IELTS Writing Task 2 draws from 7 core topic areas: technology, education, environment, society, health, work, and crime/government.
  • Precise mid-level vocabulary used correctly scores higher than advanced vocabulary used wrongly.
  • Replace vague words (good, bad, things, a lot) with precise academic alternatives immediately.

Why does vocabulary matter so much in IELTS Writing Task 2?

Lexical Resource is one of four equally weighted marking criteria in IELTS Writing Task 2, contributing 25% of your score. The Band 7 descriptor requires 'sufficient range to allow some flexibility and precision' with 'only occasional errors in word choice, spelling and word formation'. The Band 8 descriptor requires 'wide resource used fluently and flexibly to convey precise meanings'. In practice, this means using a variety of topic-specific words correctly, avoiding repetition of the same words, and choosing vocabulary that carries exactly the meaning you intend. Topic-specific vocabulary - knowing the right technical and semi-technical words for subjects like technology, environment, and health - is the fastest way to raise your Lexical Resource band.

Why Vocabulary Determines Your Band Score

The IELTS marking rubric for Lexical Resource distinguishes bands as follows:

BandLexical Resource Descriptor
Band 9Full flexibility and precision. Sophisticated control of lexical features. Rare minor errors occur only as slips.
Band 8Wide resource. Fluent and flexible use to convey precise meanings. Skilled use of uncommon lexical items with occasional inaccuracies.
Band 7Sufficient range for flexibility and precision. Uses less common vocabulary with some awareness of style and collocation. Occasional errors in word choice, spelling and word formation.
Band 6Adequate range for the task. Attempts to use less common vocabulary but with some inaccuracy. Makes some errors in spelling or word formation that do not impede communication.
Band 5Limited range. Noticeable repetition of vocabulary. Errors in spelling and/or word formation may cause some difficulty.

The gap between Band 5 and Band 7 is often a matter of replacing vague, repeated words with precise topic-specific vocabulary. This guide gives you the exact vocabulary to do that for each core IELTS topic area.

Words and Phrases to Avoid

These phrases actively hurt your Lexical Resource score. Replace them immediately in your writing practice.

How to Use This Vocabulary Effectively

1

Learn collocations, not words in isolation

The word 'alleviate' is useful, but knowing that it collocates with 'alleviate poverty', 'alleviate congestion', 'alleviate pressure' is what makes it exam-ready. When you study a word, always note 2 to 3 phrases it naturally appears in.

2

Write one sentence per new word

Do not just read a definition. Write a sentence using the word in the context of an IELTS topic you are studying. This active production is what moves vocabulary from recognition to active use in exam conditions.

3

Do vocabulary substitution drills

Take a paragraph you have written and highlight every instance of a vague or repeated word. Then replace it with a more precise alternative from this guide. Repeat weekly. Over four weeks, your default vocabulary choices shift permanently.

4

Review errors from AI feedback

When you practice on mockDe, the AI feedback identifies specific word choice errors. Keep a personal error log and revisit it weekly. Correcting the same vocabulary errors repeatedly is the most efficient route to a higher Lexical Resource band.

Test your vocabulary in a real essay
