Vocabulary Coach
Learn through definitions and context clues. The more reliably a word is known, the less often it appears.
Start a session
Suggested plan: 10–15 minutes each evening. Start with the priority deck. Known words are reviewed after 1, 3, 6, 10, 18 or 30 days; missed words stay due. Context recall uses the existing example sentences; other words may also fit a blank. Meaning quizzes use a smaller checked collection. Flashcards and the library retain all 765 original words plus 2 confirmed omissions.
How to study
Recall flashcards: Try to define the word before revealing the answer. Choose Got it only if you recalled the meaning yourself.
Meaning quiz · checked choices: Select the correct definition from four options in the 28-word checked quiz collection. Context recall · reveal & assess: Think of a word that fits the blank. Reveal the target word and assess your own recall; more than one word can fit a sentence.
