Questions & Answers about doro-e jadongchaga manhayo.

Why is the particle -에 used after 도로?

The particle -에 marks a location where something exists or happens. In 도로에 자동차가 많아요, 도로에 means “on the road” or “at the road.” You use -에 whenever you want to indicate “at/in/on” a place for verbs like 있다, 많다, 적다, 생기다, etc.

Why does 자동차 take the subject particle -가 instead of the topic particle -는?

Here you’re describing how many cars exist, so you treat 자동차 as the subject of the descriptive verb 많다. The subject particle -가 highlights that “cars” is what’s many on the road. If you used -는 (도로에는 자동차가 많아요 or 도로에는 자동차는 많아요), you’d shift the nuance to contrast or topic-comment, e.g. “As for the road, cars are many (compared to something else).”

Could you say 도로에 자동차가 있어요 instead of 많아요?

Yes, but the nuance differs:

• 도로에 자동차가 있어요 just states “There are cars on the road.”
• 도로에 자동차가 많아요 emphasizes “There are many cars.”
  If your goal is to point out quantity, 많아요 is more precise.

The dictionary form is 많다, so why is it 많아요 here?
