Examiners penalize candidates who force obscure vocabulary into essays without understanding their natural usage. The official Band 7 and Band 8 descriptors do not reward archaic vocabulary; they require “less common lexical items with awareness of style and collocation” and “very natural and sophisticated control.”
The “Thesaurus Trap” vs. High-Precision Collocations
Using rare dictionary words out of context creates unnatural prose. High-scoring candidates use precise word pairings (collocations) native to academic discourse:
| ❌ The Forced “Thesaurus” Trap | Issue | ✅ Band 8+ Academic Collocation | Context / Usage |
| A plethora of issues | Clichéd, unacademic idiom | Pose multifaceted challenges | Policy / Social essays |
| To ameliorate the bad situation | Stilted, unnatural pairing | Mitigate adverse impacts | Environmental / Economic essays |
| Ubiquitous electronic gadgets | Overused by candidates | Pervasive digital integration | Technology essays |
| Delve into the crux of the matter | Informal journalistic cliché | Examine the underlying factors | Academic inquiry |
| In a nutshell / Every coin has two sides | Prohibited idioms in academic writing | In summary / Present conflicting priorities | Structure / Analysis |

Side-by-Side Lexical Transformation
Topic: Should the government tax petrol cars to reduce urban pollution?
❌ The Forced-Vocabulary Attempt (Band 6.0–6.5)
The government should inflict huge tariffs on cars because they make cacophonous noises and nefarious poisons. This plethora of pollution will make people sick, so ameliorating this issue is paramount.
- Lexical breakdown: Unnatural word choices (inflict tariffs, nefarious poisons, cacophonous noises). Words are used as decorative synonyms rather than precise technical terms.
✅ Precise Collocation Integration (Band 8.5+)
Levying stiffer fuel excise duties on conventional combustion vehicles serves as a viable deterrent against excessive private car usage. By disincentivizing fossil-fuel transport, municipalities can simultaneously curb vehicular emissions and generate public capital to fund mass rapid transit networks.
- Lexical breakdown: Uses native academic compounds (fuel excise duties, viable deterrent, vehicular emissions, mass rapid transit networks) that communicate complex policy mechanics cleanly.
