Khmer is spoken by about 20 million people.
On our measured language map, its closest relatives are Alur, Lao and Batak Karo. If you speak one of those, much of the vocabulary will feel familiar from day one.
Structurally, verbs usually come before their objects; it is written in the Khmer script, and the course teaches the writing system letter by letter with pronunciation shown while you learn.
Every lesson is built from 2,000 real Khmer 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 1,197 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.
