IELTS Writing: Lexical Resource for Band 8+
Lexical Resource is one of the four criteria in IELTS Writing, so it counts for a quarter of your Writing band. To reach Band 7 to 9, you need words that are precise, natural and correct. Rare words do not help if they are used in the wrong way.
What Examiners Assess in Lexical Resource
Examiners look at four things: how wide your vocabulary is, whether you use words correctly, whether the words suit the context, and whether you combine words naturally. Natural word combinations, such as "make a decision" or "a sharp rise", are called collocations.
At higher bands, they also check that you avoid repeating the same words, use the correct word forms, and use less common words only where they make your meaning clearer.
Why Students Lose Marks on Lexical Resource
The most common problem is repetition. Band 6 essays often use the same few words again and again. The second problem is the opposite: using impressive-sounding words that do not quite fit the sentence.
Other common mistakes are using the wrong word form (for example, "economic" instead of "economical"), choosing words that are too informal or too formal, and putting words together in ways a native speaker would not.
Common Error Patterns
- Repetition: using the same word throughout the essay.
- Wrong meaning: using an advanced word that does not mean what you think.
- Wrong level of formality: "kids" or "stuff" in an academic essay.
- Unnatural combinations: "do a decision" instead of "make a decision".
Band 6 vs Band 8+ Comparison
A Band 6 essay has a limited range and noticeable repetition. Words are mostly correct but basic, and the few advanced words are sometimes misused.
A Band 8 essay uses a wide range of words with very few errors. Word combinations sound natural, and less common words are used because they are more exact, not to impress.
Example Comparison
Band 6 approach: "Technology is very important. Technology helps people. Technology makes life better. Many people use technology. Technology is good for communication." (The same word five times and very simple choices.)
Band 8+ approach: "Technology now shapes almost every part of daily life. Video calls let families stay in touch across continents, and online banking saves people hours each month. These everyday benefits explain why so many people have come to depend on their devices." (Varied, precise words that say exactly what is meant.)
Actionable Strategies for Improvement
1. Vary Your Words
When you notice you are repeating a word, change the sentence rather than just swapping in a synonym. For example, instead of repeating "problem", name the actual problem: "traffic jams", "rising rents", "a shortage of nurses".
2. Use Words You Know Well
A simple word used correctly is better than a complex word used wrongly. Before using a new word in the exam, make sure you know its meaning, its grammar and the words it usually goes with.
3. Learn Words in Pairs and Groups
Learn collocations, not single words: "make a decision", "take action", "carry out research", "pose a threat", "a significant increase". This makes your writing sound natural and shows real control of English.
4. Match the Level of Formality
Task 2 needs a formal but clear style. Avoid informal words such as "stuff", "things" and "a lot of", but do not replace every simple word with a long one. Clear and formal is the goal.
5. Build Topic Vocabulary
Prepare words for common IELTS topics: education, technology, the environment, health and work. Having these ready lets you write precisely under time pressure. Practise using them in sentences, not just in lists.
Practice and Feedback
Vocabulary improves fastest when someone points out exactly which words were wrong or repeated. Write regularly under timed conditions and get feedback on range, accuracy and word choice.
AI writing feedback can highlight repeated words, unnatural combinations and misused words in your own essays, so you know what to fix next time.
Conclusion
Band 8 Lexical Resource comes from range, accuracy and natural word choice, not from rare words. Vary your language, use words you know well, learn words in combinations and match the formality of the task.
Practise regularly with feedback, and focus on writing naturally rather than trying to impress.
