❓ Why do Koreans say “지민이는…” and “지민이가…”?
You just learned how to say your nationality like “나는 한국 사람이야” (I am Korean). But suddenly you hear people say:
“지민이는 한국 사람이야.”
“지민이가 한국 사람이야.”
Both mean “Jimin is Korean,” so… why two versions?
Don’t worry. Let’s break it down 👇
🗣️ Dialogue 1: In a classroom (Self-introduction)
👨: 안녕. 나는 지민이야. 반가워.
(Hi, I’m Jimin. Nice to meet you!)
👩: 나는 리사. 화성에서 왔어. 너는?
(I’m Lisa from Mars. You?)
👨: 나는 한국 사람이야. 😧
(I am Korean.)
This situation is about giving general, background information about yourself, so 은/는 (topic marker) fits naturally.
🗣️ Dialogue 2: In the student hall (Identity emphasis)
🧑🦱: 누가 우리 반에 화성인이 있대. 누구야?
(I heard someone from Mars is in our class. Who is it?)
🧝♂️: 난 아니야.
(Not me.)
👩: 나야. 내가 화성인이야.
(It’s me. I’M the Mars person.)
Here the speaker is emphasizing **who exactly** is the Mars person. So 이/가 (subject marker) is natural.
📘 Understanding Korean Markers
✔ Korean Subject Marker (이/가)
- Points out the subject clearly.
- Used in longer or complex sentences to identify who/what is acting.
- Creates emphasis or contrast.
- Feels similar to using “the” in English.
✔ Korean Topic Marker (은/는)
- Introduces the topic of the sentence.
- Used in self-introductions or general statements.
- Sets the background context.
