The accusative case for direct objects
Russian uses different word endings to show what role each noun plays in a sentence. The direct object — the thing the verb acts on — takes the accusative case. The good news: for many nouns, this case looks identical to the dictionary form.
Why cases exist
In English, word order tells you who does what: 'The cat sees the dog' is different from 'The dog sees the cat'. In Russian, the endings carry that information instead, so word order is much freer. The accusative is the case that says 'I'm the object'.
The accusative endings
Inanimate masculine: same as nominative — no change. (стол → стол). Inanimate neuter: same as nominative. (окно → окно). Feminine -а → -у. (книга → книгу). Feminine -я → -ю. (песня → песню). Feminine -ь: no change. (ночь → ночь). Plurals are mostly the same as nominative for inanimate nouns (we'll cover animate plurals later). Summary: only the feminine -а / -я ending visibly changes for inanimate objects.
Animate masculine — heads-up
If the masculine direct object is a person or animal (animate), it takes a different ending — like the genitive — but we'll cover that in a later lesson. For this lesson, stick to inanimate objects.
Why this matters with feminine nouns
If you say Я читаю книга — that's wrong. Книга is the subject form. As the object, it must become книгу: Я читаю книгу. Russians will understand you, but it's the equivalent of saying 'I him see' in English — it's grammatically marked as wrong.
