Chamorro is spoken by about 80,000 people. Guam and the Northern Marianas. Transmission to children largely stopped in the twentieth century; most fluent speakers are elderly.
On our measured language map, its closest relatives are Pangasinan, Waray and Spanish. If you speak one of those, much of the vocabulary will feel familiar from day one.
Every lesson is built from 2,000 real Chamorro 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, 1,249 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 946 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.
