English word knowledge test
Estimate how many English words you know. Words are drawn from a frequency list and the test adapts as you go — from everyday vocabulary toward rarer items.
- Know it? Swipe right, press →, or tap I know it.
- Don’t know it? Swipe left, press ←, or tap I don’t know it.
- Undo with Z or Backspace if you mis-tap.
