Building Vocabulary
Synonyms, homophones, roots and context clues
Vocabulary grows fastest through reading rather than lists, because words met in context arrive with their usage attached.

This unit breaks down into 21 short steps and 128 questions, starting at difficulty 1 and building to 3. Below you can see exactly what it covers, how the path is structured, and worked examples with explanations.

Where these questions come from. Each unit starts as a plan of the concepts it should cover and the difficulty it should span. Questions are written against that plan with AI assistance, then checked by a validator that rejects anything without a single defensible answer, an explanation, or plausible wrong options. How we write questions sets out the whole process, and corrections are fixed in the bank and reach the site and the app the same day.
