Tongan is spoken by about 210,000 people. Tonga plus larger Tongan communities in New Zealand, Australia and the United States.
On our measured language map, its closest relatives are Samoan, Kosmospik and Taiwanese Hokkien. If you speak one of those, much of the vocabulary will feel familiar from day one.
Every lesson is built from 2,000 real Tongan 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, 1,469 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 958 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.
