Questions & Answers about Водитель проверил двигатель.
Why is водитель the subject here?
Водитель is in the nominative case, which is the normal case for the subject of a sentence. In a neutral Russian sentence, the subject often comes first, so Водитель проверил двигатель is read naturally as The driver checked the engine.
What case is двигатель, and why doesn’t its ending change?
Двигатель is the direct object, so it is in the accusative case.
However, for many masculine inanimate nouns, the accusative singular looks exactly the same as the nominative singular. So:
- nominative: двигатель
- accusative: двигатель
That is why you do not see a new ending here.
If водитель and двигатель both look unchanged, how do I know who did the action?
That is a very common question. In this sentence, you mostly know from:
- Normal word order: Russian often uses subject + verb + object as the neutral order.
- Meaning/context: a driver checking an engine is more natural than an engine checking a driver.
So Водитель проверил двигатель is understood as The driver checked the engine.
This is one of those cases where Russian relies on more than just endings.
