How the course uses these words
The game introduces words in the order shown. Each word comes with several sentences: easy ones first, then medium and hard ones that combine it with words the player already knows. Players meet them in quests, mini-games, and conversations rather than as a list.
The intro course covers the first words. The expansion continues it inside the game with more words and easy sentences for each one.
Where the list comes from
The words are drawn from a vocabulary bank graded by CEFR level and ordered for a first course, so the most useful words for simple conversations come first. The sentences are written for the course, and each one is recorded in two voices.
Nothing here is a sample. The page is built from the same course files the app downloads, so it changes when the course does.
