The Why
English doesn't have these "little tags." But your brain tries to translate them into one English word.
Do not translate!
For now, empty your brain a bit.
They are tags that guide the listener.
Same meaning, Different focus
The tags keep the meaning clear—even when the order changes.
These two can both look like “I am a student” in English:
저는 학생이에요.
제가 학생이에요.
But the feeling is different.
저는 학생이에요 = I am student
제가 학생이에요. = I’m the student, not someone else.
The simplest map
은/는 = topic (what we are talking about)
이/가 = subject (the one that does it / is it)
That's enough for beginners.
은/는 'About X…'
It often feels like "About X…" in English.
저는 민재예요. (About me: I'm Minjae.)
이거는 커피예요. (About this: it's coffee.)
한국은 겨울이 추워요. (About Korea: winters are cold.)
이/가 'This one'
It points to the exact subject.
누가 왔어요? → 민재가 왔어요.
뭐가 좋아요? → 이게 좋아요.
누가 학생이에요? → 민재가 학생이에요.

Most important thing is
Try to feel the difference.
Listen a lot.
If you keep hearing it in real sentences, your “sense” will grow.
