Known and mastered
What new, learning, known and mastered mean, what moves a word up, and how to read your map.
Every word sits on one of four steps. Your headline number, x / 1,000 known, counts known and mastered words together.

- Your map: one tile per word, the most used first, row by row.
- New: not studied yet. Words come up in order as you follow your path.
- Learning: studied, but not solid yet.
- Known: you can recall the word itself.
- Mastered: you can use it, in its forms and in a sentence, and it has stuck.
Learning → known
A word becomes known once you’ve typed it correctly with the word bank hidden, a few times, so that spaced repetition is confident you’ll remember it. Answers with the bank showing keep it at learning, however many you get right.
Any card counts: the word on its own, one of its forms, or the word in a sentence.
Known → mastered
Known means you can recall the word. Mastered means you can use it. A word is mastered when, with the bank hidden, you’ve:
- typed it from English;
- typed its key forms, where it has them:
- nouns: the plural, and one form with an article, a possessive or a preposition;
- verbs: the present tense, two more tenses, and two different persons;
- adjectives: a feminine form and a plural;
- filled it into its sentence;
- and remembered it for 3 weeks.
Each word’s page has a To master checklist that shows exactly what’s left.

- A step you’ve done.
- A step still to do: here, the word in a sentence.
- How long the app is confident you’ll remember it, out of the 21 days needed.
To work through the steps, turn on the forms in Add practice types when you set up a batch, or use Drills for verbs.
Words can move back
Both steps are worked out from your answers, so they stay honest. If you start missing a known word, it can drop back to learning until you get it right again. That’s not lost work: it’s the app making sure the word comes back often enough.
Color-blind friendly marks
Mastered purple and known teal are the same lightness. In your account, turn on Color-blind friendly marks to add a pale dot to every mastered tile on the map.
