Why Simple Vocabulary Beats Fancy Words in IELTS Band 7‑9 Essays

A striking 33.5 % of the words in band 7, 8 and 9 IELTS essays are simple connectors such as “the”, “to”, “of”, “and” or “because”. This figure comes from an analysis of 100 real essays and it completely overturns the common belief that a high‑scoring essay must be packed with sophisticated vocabulary.

The Speaker’s Method vs. Conventional Advice

Most preparation courses tell students to chase a wide range of high‑level words, building long lists of “big” vocabulary. The speaker’s approach flips that script: use the words you already know, apply them accurately, and focus on topic‑specific terms. Rather than expanding the lexical range for its own sake, the method stresses precision and relevance.

Data‑Driven Insights

Top Words and Keywords

The twenty most frequent words—“the”, “to”, “of”, “in”, “that”, “are”, “this”, “they”, etc.—account for more than a third of every essay examined. The top ten content keywords (e.g., “people”, “children”, “time”, “companies”, “parents”, “life”, “school”, “health”, “employees”, “diet”) are also simple and often directly tied to common Task 2 topics such as education and health. Knowing accurate synonyms for these core words is the most efficient way to vary language.

Linking Words

Common linking expressions like “in conclusion”, “however”, “although”, “for instance”, “as a result”, “therefore” are short, functional, and highly rewarded when used correctly. Examiners do not grant extra marks for ornamental linking; they look for appropriate and accurate usage. Band 9 writers actually employ fewer linking words than band 7 writers, relying on a handful of reliable connectors.

Word‑Level (CEFR) Distribution

Software from Cambridge English shows that about 90 % of the vocabulary in high‑band essays falls within the A1‑B2 range (simple to intermediate). Only roughly 7 % are C1‑C2 words, used sparingly as “sprinkles” on a cake whose main ingredients are everyday words. Topic‑specific C1/C2 terms such as “accountable”, “adolescent”, “advocate”, “allocate” and “aspirations” are functional rather than decorative.

Key Takeaways from the Data

• Simplicity, accuracy, and the use of existing vocabulary drive higher scores.
• Complex words should be treated as optional “sprinkles”, not the base of the essay.
• Topic‑specific vocabulary, even if less common, outweighs generic high‑level words.
• Mastering a small set of reliable linking phrases is more beneficial than memorising many fancy connectors.
• Successful students focus on precise synonyms for everyday words to achieve variation.

Conclusion

Band 9 essays are built on everyday vocabulary that writers already know, with roughly 90 % of the words falling into the simple A1‑B2 range. While variation remains important, the most effective strategy is to master accurate synonyms for common terms and to use a handful of functional linking words. Complex vocabulary should be reserved for moments when a simple word cannot convey the intended meaning, acting as the “sprinkles” that enhance, rather than define, a high‑scoring essay.
