Does 친구가 mean my friend or a friend?
On its own, 친구가 is usually understood as a friend or (my) friend depending on context. Korean often drops possessives like 내(=my) when they’re obvious.
- If you want to be explicit: 내 친구가 = my friend
- If you mean a friend of mine (less specific): 친구 한 명이 / 아는 친구가
Why are there two 가 particles in the sentence: 친구가 and 비가?
They mark two different subjects in two different “layers”:
- 비가 is the subject of the content being reported: 비가 오다 = rain comes / it rains
- 친구가 is the subject of the reporting: (My) friend says…
So the structure is basically: [친구가] [내일 비가 온다고] 말해요 → 온대요.
What does 온대요 mean grammatically?
