Betawi is spoken by about 6 million people. Soft: there is no clear border between Betawi and colloquial Jakarta Indonesian, so the count depends where you cut.
On our measured language map, its closest relatives are Indonesian, Minang and Malay. If you speak one of those, much of the vocabulary will feel familiar from day one.
Every lesson is built from 2,000 real Betawi 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, 1,461 patterns so far, 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 967 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.
