Grammar Rule in 30 Seconds

Russian words change their endings based on their job in the sentence, which we call 'cases'.

  • Nominative: The subject of the sentence (e.g., 'Кот спит' - The cat sleeps).
  • Accusative: The direct object receiving action (e.g., 'Я вижу кота' - I see the cat).
  • Prepositional: Used for location with 'в' or 'на' (e.g., 'в доме' - in the house).
Noun (Base) + Ending = Role in Sentence
