Luma has about 240 stems — core concepts that cover the essentials of everyday conversation. Each stem takes one of four vowel endings to become a noun, verb, modifier, or grammatical word. These 14 short lessons teach you all of them, one at a time.

Each lesson tells a short story, introducing one new stem per sentence. Every sentence has full audio, a natural English translation, and a literal gloss. Lessons also include a dialog, remix sentences for extra practice, and a downloadable Anki deck for spaced-repetition review.
