Fluency is less about how many words you know and more about how densely they're connected. When you can swap important for crucial or essential mid-sentence, you never get stuck — you route around gaps. Synonym questions train exactly that connection. Each word in this quiz comes from our English decks, where it also carries a plain-English definition, a CEFR level, and register notes — study them free with spaced repetition, or check your overall range first with the English vocabulary size test.
Each round samples 10 words from our CEFR-leveled English decks that carry editor-curated synonyms. You pick the synonym from four options; wrong options are picked from words at a similar level and are never actual synonyms of the target, so every question has exactly one right answer. Retaking gives you a fresh sample.
Translations test whether you recognize a word. Synonyms test whether you own it: connecting a word to its alternatives within English is what lets you rephrase, understand paraphrase, and sound natural. Research on lexical networks shows words learned with their neighbors are recalled better than words learned in isolation.
Questions are sampled across CEFR levels from A1 to C2 and each question shows its level chip. Early questions tend to be common words with everyday synonyms; the hardest draw on C1/C2 vocabulary where distinguishing near-synonyms is genuinely difficult.
Yes — free and no signup. If you want to actually learn the words you miss, every English deck on Words on Repeat is also free to study with FSRS spaced repetition.
