Master the syntax conventions of academic English — complex clauses, passive constructions, and hedging.

Core Syntactic Features

  • Long NP subjectThe widespread adoption of digital platforms has transformed…
  • PassivisationFocus on action: The data were collected over twelve months.
  • PostmodificationA study conducted by independent researchers in 2023 found…
  • Embedded clauseThe claim that inequality has widened is well-supported.

C2 Academic Conventions

  • Avoid first person where possible: prefer it was found that / the study shows
  • Hedge appropriately: appears to / tends to / would seem to indicate
  • Nominalise: verbs and adjectives become noun phrases for density
  • Vary sentence length: a short sentence after a complex one creates clarity and impact

Common C2 Mistakes

  • ❌ We found out that → ✅ It was found that / The findings indicate
  • ❌ things / stuff / a lot of → ✅ factors / elements / a significant proportion of
  • ❌ Passive overuse — mix passive with long-NP subjects for variety
  • ❌ Sentence fragments in formal writing → ✅ complete grammatical units
