Every lesson is built from 2,000 real Santali sentences, aligned with their translations word by word and piece by piece, so you always see how the sentence actually works instead of memorizing flashcards. The grammar is discovered from the sentences themselves, and a spaced-repetition quiz teaches it in the order that unlocks the most of the language first. Our measured estimate for reaching conversational level from English is about 1,346 hours of study. Read how it works.
Speaker figures follow Ethnologue and national censuses, rounded; the difficulty estimate is calibrated against U.S. Foreign Service Institute data.
