Questions & Answers about kuruma wa shingou de tomarimasu.

What does the particle は do in 車は信号で止まります?

The particle は marks the topic of the sentence. Here, 車は means “as for the car,” indicating that the sentence will say something about the car (namely, that it stops at a traffic light). It’s not the subject-marker が, but a way to set the topic and often contrasts or generalizes.

Why is 信号 followed by で instead of に?

The particle で marks the place where an action occurs. In this case, 信号で止まります means “(it) stops at the traffic light.” If you used に, it would sound like the car moves into or towards the light, which isn’t the intended meaning.

Can I replace は with が in this sentence?

Yes, you can say 車が信号で止まります, but it shifts the nuance. 車が simply marks “the car” as the subject, focusing on the fact that a car stops. 車は sets “the car” as an assumed topic, perhaps contrasting with other vehicles.

Why is the verb 止まります in the polite form?

止まります is the polite present/future tense of 止まる (“to stop”). In everyday speech, you might hear the plain form 止まる (“車は信号で止まる”), but textbooks and polite conversation often use 止まります to maintain a polite tone.
