Questions & Answers about chinguga byeongwone wasseoyo.
What is the function of the particle 가 in 친구가?
가 is the subject-marker that attaches to a noun ending in a vowel. It tells us that 친구 (friend) is the one performing the action “to come.”
Could we use 은/는 instead of 가 here? What difference would that make?
Yes, you can say 친구는 병원에 왔어요. In that case, 는 marks 친구 as the topic rather than just the subject. It often implies contrast or emphasis (“As for my friend, he/she came to the hospital”), whereas 가 simply identifies the subject.
What does 에 do in 병원에 왔어요?
에 marks a location as a destination when used with motion verbs like 오다 (“to come”). So 병원에 왔어요 literally means “(someone) came to the hospital.”
Why don’t we use 에서 after 병원 instead of 에?
에서 indicates the place where an action takes place or originates (“at/in/inside”). But when your verb describes motion toward a place (like 오다 or 가다), you use 에 to show the destination. If you said 병원에서 왔어요, it would mean “(someone) came from the hospital.”
