🇷🇺 The best dictionaries for learning Russian

Bundles the normative dictionaries (explanatory, orthographic, stress), the full spelling and punctuation rules, and a long-running expert help desk answering usage questions. This is where you settle arguments about commas, declining foreign names, or which stress is correct. Free and enormous. Everything is in Russian and written for native professionals, so it is only workable from around B2.

The dictionary most Russian learners end up living in: every entry shows the stress, the complete declension or conjugation table with accented forms, audio, and examples drawn from a 350,000-sentence bank. Stress marking alone justifies it, since printed Russian omits them. Free, open data under CC BY-SA, with apps available. Coverage of rare or very new words is thinner than a commercial dictionary's.

Over 100 language editions; the English edition alone has millions of entries covering hundreds of languages, with IPA, declension and conjugation tables, etymologies and usage notes that commercial apps usually paywall. The etymology sections are quietly one of the best vocabulary-retention tools available. Being crowd-sourced, coverage is uneven and rare entries can be wrong — cross-check anything unusual against a native-language dictionary.

Around 6 million words recorded by native speakers across 400+ languages, usually with several accents per word so you can hear regional variation. Free to search on the site; the paid tiers are aimed at API users and bulk audio downloads. Indispensable for names, place names and anything a TTS voice would mangle — many learners wire it directly into Anki for card audio.
