Why academic vocabulary matters for exam scores

IELTS and TOEFL writing scores reward lexical range, using precise academic vocabulary instead of basic words. Examiners look for natural, contextually appropriate word choice, not forced complexity.

  • Replace "very big" with "substantial" or "considerable."
  • Use "demonstrate" instead of "show" in analytical writing.
  • Pair abstract terms with concrete examples to show genuine understanding.

High-frequency academic words

The Academic Word List (AWL) contains 570 word families that appear across many disciplines. Knowing the top 100 covers a large portion of academic text.

  • Analysis, approach, assessment, authority, concept, context.
  • Define, derive, distribute, economy, environment, establish.
  • Evidence, factor, function, identify, indicate, interpret.

Common exam writing mistakes

Using big words incorrectly hurts more than using simple words correctly. Accuracy always beats complexity.

  • Don't use "utilize" when "use" is natural, forced formality reads as unconfident.
  • Avoid memorized phrases that sound rehearsed ("In this modern era...").
  • Use transition words to connect ideas, not just to pad word count.
