Russian is spoken by about 210 million people. The second-language figure is falling fast: speakers across the former Soviet space dropped from 119 million in 1990 to under 80 million by 2018.
On our measured language map, its closest relatives are Belarusian, Ukrainian and Serbian. If you speak one of those, much of the vocabulary will feel familiar from day one.
Structurally, verbs usually come before their objects; words are built from many smaller pieces, which our course teaches piece by piece; it is written in the Cyrillic 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 Russian 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, 1,510 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 1,141 hours of study. Read how it works.
Most apps only teach Russian through English, if they teach it at all. These starting languages already have a built course, and any other published language can be paired on request:
Speaker figures follow Ethnologue and national censuses, rounded; the difficulty estimate is calibrated against U.S. Foreign Service Institute data.
