How many English words do you know?
Most learners have no real idea how big their English vocabulary is. This test gives you a fast, honest estimate: it shows you English words in context and adapts to your level, homing in on the point where recognition turns into guessing.
English has an enormous vocabulary and leans on phrasal verbs and collocations, so your true word count is easy to underestimate. This test gives you a quick, honest estimate.
How the test works
- Answer ten quick questions. Each one shows a real word in context, and the test adapts as you go to zero in on your level.
- We estimate your vocabulary. Words are ranked by how common they are, so your answers place you on a frequency curve and estimate how many words you know.
- See your level. You get a vocabulary estimate and a level from Beginner to Master — plus the fastest way to grow it.
What your score means
The most common 1,000 words cover about 88% of everyday speech, and 2,000–3,000 gets you comfortable conversation. Your estimate shows which band you're in and how far the next milestone is.
