How this works

We extract its five most interesting vocabulary words using a word-frequency filter (no proper nouns, no boring long words), show you the sentence each appeared in, and ask you to define them in your own words. Your answers are graded against a real dictionary definition — the meaning is never invented by an AI, so a wrong definition can't slip through. Pass at 70%+ to log a badge with your name on it. Self-study to grow your vocabulary — not a credential.
