Core Grammar / Cases & Declension
Thirty anchor nouns, fifteen per vocabulary and five per gender, declined through all six cases in both numbers. Every form and every example sentence is playable. Pick one noun per gender, drill it until the endings feel automatic, then use the rest to confirm the pattern holds.
The two tabs teach identical grammar with different vocabulary. Pick one noun per gender and drill those three until the endings feel automatic, then use the others to confirm the pattern holds, or to notice where a soft stem diverges. In the Military tab the cleanest hard-stem anchors are солда́т, маши́на and ме́сто; in the Café tab they are стол, ча́шка and блю́до.
Every case row carries the singular and plural form plus an example sentence for each, so you can hear the ending in a real utterance rather than in isolation. Translations are hidden until you press Перево́д.
