Questions & Answers about jeolmeun sarami unjeonseoge anjassseupnida.

Why is 젊은 used instead of 젊다?

젊다 is the dictionary form, meaning to be young.
When a descriptive verb like 젊다 directly modifies a noun, it changes form:

• 젊다 = to be young
• 젊은 사람 = a young person

So in this sentence, 젊은 사람 means a young person.

This is similar to how Korean often turns descriptive verbs into noun modifiers:

• 작다 → 작은 집 = a small house
• 예쁘다 → 예쁜 꽃 = a pretty flower

So 젊은 사람이 is simply the/a young person as the subject.

Why is it 사람이 and not 사람은?

이/가 and 은/는 are different subject/topic markers.

Here, 사람이 uses 이, which marks 젊은 사람 as the grammatical subject. It often sounds more like a young person is being introduced or identified as the one doing the action.

• 젊은 사람이 운전석에 앉았습니다.
  = A young person sat in the driver’s seat / It was a young person who sat in the driver’s seat

If you said:

• 젊은 사람은 운전석에 앉았습니다.

then 은 would make the young person the topic, often with a contrastive or already-known feeling, like:

• As for the young person, they sat in the driver’s seat.

So 이 is very natural here if you are simply describing what happened.

Why does the subject marker become 이?
