IELTS Vocabulary: What Band 9 Students Do Differently in 2026
IELTS Advantage
Overview
This video challenges the common misconception that high IELTS scores require complex vocabulary. Analyzing hundreds of high-scoring essays, the speaker reveals that successful students prioritize accuracy and simplicity, using common, topic-specific words effectively. The data shows that over 90% of words in band 7-9 essays are basic vocabulary, with complex words used sparingly as "sprinkles." The key to high scores lies in mastering existing vocabulary, using simple words accurately, and employing topic-specific terms and common linking words correctly, rather than memorizing extensive lists of difficult words.

Chapters
- Contrary to popular belief, high-scoring IELTS essays (Band 7-9) primarily use simple, common words.
- Data from 100 analyzed essays shows that over 33.5% of words are basic functional words like 'the,' 'to,' and 'of'.
- The focus for high scores should be on accuracy with simple words, not on increasing vocabulary range with complex terms.
- Successful students leverage their existing vocabulary effectively rather than learning extensive new word lists.
Understanding this fundamental principle helps learners shift their focus from memorizing difficult words to mastering the accurate use of everyday language, which is more effective for achieving a high IELTS score.
The top 20 most frequent words in Band 7-9 essays include 'the,' 'to,' 'of,' 'and,' 'in,' 'that,' 'is,' and 'it,' which are all basic English words.
- High-scoring essays often feature simple, topic-specific words relevant to the essay's subject.
- Complex words like 'plethora' are less effective for discussing common IELTS topics such as education or health than simpler, direct terms.
- Learners should identify common themes in IELTS (e.g., people, children, time, companies) and master vocabulary related to them.
- While word repetition is sometimes necessary, having accurate synonyms for common topic-specific words is important for variation.
This highlights the importance of understanding the context of the essay and using vocabulary that directly addresses the topic, rather than relying on generic, complex words that may not fit.
Instead of using a complex word like 'plethora' to describe a large amount, it's more effective to use simpler, topic-specific words that directly relate to the essay's subject matter, such as 'many' or 'numerous' when discussing education or health.
- Common linking words (e.g., 'however,' 'for instance,' 'in conclusion') are sufficient and effective for high-scoring essays.
- Examiners value the accurate and appropriate use of simple linking words over complex or varied ones.
- Learners should focus on mastering a few essential linking words for specific functions (like concluding or giving examples) rather than memorizing many alternatives.
- Band 9 students often use fewer linking words than Band 7 students, indicating that simplicity and accuracy are key.
This understanding helps students allocate their study time more efficiently by focusing on mastering a core set of functional linking words rather than getting lost in a vast array of complex options.
For concluding an essay, mastering one simple phrase like 'In conclusion' is more effective than learning multiple complex concluding phrases, as you will only write one conclusion.
- Analysis using CEFR levels (A1-C2) shows that 90% of words in high-scoring essays fall into the simpler A1-B2 categories.
- High-level C1 and C2 words are used sparingly, less than 10% of the total vocabulary, and only when simpler words are insufficient.
- The primary goal of the IELTS writing test is clear communication with the examiner.
- Complex words are not necessarily 'difficult' words but rather topic-specific, functional words that students may already know.
This clarifies that the goal isn't to impress with obscure vocabulary but to communicate ideas clearly and effectively using a well-chosen, accurate vocabulary, even if it's mostly simple.
The vocabulary in high-scoring essays is often described as a cake: the majority (90%) are simple ingredients like flour and sugar (everyday words), with a small percentage (10%) of sprinkles (complex, topic-specific words) for enhancement.
- Learners should focus on simple, accurate, topic-specific words within their existing vocabulary.
- A free PDF resource is offered, containing 50 safe and effective synonyms commonly used in Band 7-9 essays.
- The video promotes a personalized feedback and study plan service at a significantly reduced price for YouTube viewers.
