Questions & Answers about Шум в коридоре заставил меня выключить телевизор.

Why is шум in the nominative case?

Because шум is the subject of the sentence — it is the thing that caused the action.

• шум = noise
• In this sentence, the noise is what made the speaker do something.

So Russian uses the nominative for the subject:

• Шум в коридоре заставил меня выключить телевизор.

Literally, the structure is something like:

• [The noise] made [me] [turn off the TV].

Why is it в коридоре, not в коридор?

Because в коридоре means in the corridor / in the hallway, describing location.

With в, Russian often uses:

• Prepositional case for location: в коридоре = in the corridor
• Accusative case for motion toward something: в коридор = into the corridor

Here there is no movement. The sentence is saying where the noise was:

• Шум в коридоре = noise in the corridor

So коридоре is prepositional singular of коридор.

Why is it заставил, and not some other form like заставило or заставила?
