Academic vocabulary for TOEFL

The academic vocabulary TOEFL reading and listening rely on: common academic words, word families, and subject vocabulary from biology to history.

In this lesson you will

  • Learn high-frequency academic words
  • Recognise word families and prefixes
  • Build subject vocabulary for academic passages and talks

Learn

Academic passages and talks cover subjects like biology, geology, astronomy, history, art, psychology and economics. You don’t need expert knowledge — but academic words appear everywhere.

High-frequency academic words: analyse, approach, assume, consist of, derive, distinct, evidence, factor, function, indicate, interpret, significant, structure, theory, vary.

Word families help guess meaning: evolve, evolution, evolutionary; migrate, migration, migratory. Prefixes: pre- (before), inter- (between), sub- (under), trans- (across), bio- (life), geo- (earth).

Learn in context: keep a notebook with a sentence for each word, and review with spaced repetition (the KitWren vocabulary trainer includes academic and exam sets).
