Questions & Answers about soneseo piga jogeum nassseupnida.
Yes. 났습니다 is the formal past-tense form of 나다.
In this sentence, 나다 does not mean just to happen or to occur in a general sense. It often means to come out, to appear, or to break out, depending on context.
So:
- 피가 나다 = blood comes out / to bleed
- 피가 났습니다 = blood came out / was bleeding
This is a very common Korean way to describe bleeding. Korean often expresses this idea as blood came out, rather than using a verb exactly like English bleed.
Because 피 is treated as the thing that came out, so it is the subject of 나다, not the object.
- 피가 나다 is the standard pattern.
- Here, 가 marks 피 as the subject.
So the sentence is built like:
- 손에서 = from the hand
- 피가 = blood (subject)
- 조금 = a little
- 났습니다 = came out
A literal way to think of it is:
From the hand, blood came out a little.
That is why 가 is natural here.
