TOEFL Synonym Quiz

TOEFL academic synonym quiz

Study three related synonyms, choose the best fourth synonym, and move automatically to the next question after feedback.

What you will learn

TOEFL Synonym Quiz develops your ability to recognise paraphrased academic vocabulary — a skill directly tested in TOEFL Reading vocabulary questions. You will learn synonym families (groups of words with similar meanings like "increase, rise, grow, escalate, surge") and practise identifying the correct synonym from context. This exercise builds the vocabulary depth needed for scoring 25+ in TOEFL Reading.

How to play the Synonym Quiz

Each question shows you three related synonyms and asks you to identify the correct fourth synonym from two options. This tests your ability to recognise vocabulary relationships — the same skill tested in TOEFL "vocabulary in context" questions.

After selecting your answer, you receive instant feedback showing the correct relationship. The system uses spaced repetition to bring back synonym families you found difficult.

Complete 10 questions per session. Each correct answer earns XP and strengthens your academic vocabulary network.

💡 Tips for better scores

  • Focus on the shared meaning across all three given synonyms before looking at the options.
  • Academic synonyms often differ in formality: "start" (informal) → "commence" (formal) → "initiate" (academic).
  • Many TOEFL Reading questions test whether you can identify a synonym used in a specific context.
  • Learn synonym chains: big → large → substantial → considerable → significant.

How synonym knowledge improves TOEFL scores

Approximately 20-25% of TOEFL Reading questions directly test vocabulary knowledge by asking you to identify the meaning of a word "as used in the passage." These questions require you to choose the correct synonym from four options, and the correct answer is often a less common academic synonym rather than the everyday equivalent.

Beyond direct vocabulary questions, synonym knowledge improves your performance across all TOEFL sections. In Listening, recognising that a lecturer's use of "substantial" means the same as "considerable" helps you follow academic arguments. In Writing, using varied synonyms instead of repeating the same word demonstrates the lexical sophistication that earns higher scores.

Example practice items

Here are some examples of the type of content you will encounter at this level:

  • "enhance, improve, strengthen → elevate (to raise to a higher level)"
  • "significant, considerable, substantial → noteworthy (deserving attention)"
  • "investigate, examine, analyse → scrutinise (to look at very carefully)"
  • "hinder, impede, obstruct → hamper (to prevent free movement or progress)"
