Russian is spoken by roughly 255–260 million people: around 150 million native speakers and more than 100 million who use it as a second language across the former Soviet republics of Central Asia, the Caucasus, and Eastern Europe. It is the most geographically widespread language of Eurasia, one of the six official languages of the United Nations, and carries real weight in diplomacy, aerospace, energy, and international journalism. Large Russian-speaking communities also live in Israel, Germany, the Baltic states, and the United States — reach that extends far beyond Russia's own borders.

Russian distinguishes itself from Western European languages in ways that go well beyond the alphabet. The 33-letter Cyrillic script includes vowels that signal consonant softness and two silent signs — the hard sign ъ and soft sign ь — that affect pronunciation without producing a sound of their own. Six grammatical cases change the endings of every noun, adjective, and pronoun; three genders exist but there are no articles at all; and nearly every verb comes as an imperfective/perfective pair encoding whether an action is ongoing or completed. Word stress is free and mobile, unstressed о reduces toward 'a' (аканье), and almost every consonant has a hard and soft pair — yet Russian is not tonal, and its spelling is more phonemic than English.

The U.S. Foreign Service Institute rates Russian Category III: roughly 1,100 class hours for an English speaker to reach professional working proficiency, versus 600–750 hours for Spanish or French. The six-case system, verbal aspect, three genders, and unfamiliar script are the main obstacles — none of which have direct equivalents in English. That said, Cyrillic itself is quicker to master than people expect: most learners read simple words within a few days and read fluently inside a fortnight. Slavic-language speakers — Polish, Ukrainian, Czech, Bulgarian — arrive with shared vocabulary, case logic, and aspect already embedded, while German speakers find the free word order and case endings at least conceptually familiar.

Langula's 80-lesson A1-to-B2 path mirrors how Russian actually layers in: the Cyrillic script and core sound system come first, then the most common cases, then verbal aspect and the full six-case matrix, then participles, gerunds, and abstract vocabulary — with a certificate marking each level. The Leitner flashcard system (five spaced-repetition boxes) drills the case endings Russian demands through distributed practice rather than rote cramming. In-browser pronunciation scoring gives instant feedback on hard/soft consonant pairs and vowel reduction, the features learners struggle most to self-monitor. And because Langula is genuinely free, browser-based, and needs no sign-up, you can start sounding out Cyrillic on any phone or laptop right now.
