After this page, you can decide between 은/는 (eun/neun) and 이/가 (i/ga) by asking what you want your listener to focus on.
10-second answer
The short answer
은/는 (eun/neun) usually tells the listener what you're talking about. 이/가 (i/ga) often identifies, emphasizes, or presents the subject. The difference is not simply "topic vs subject" — it becomes clearer through context and focus.
Quick check — did that land?
1. Someone asks 누가 왔어요? (Who came?). Which answer sounds natural?
은/는 or 이/가? Don't memorize topic equals one and subject equals the other.
Start Here
Imagine someone asks: "Who is a student?" You might answer:
제가 학생이에요.
je-ga haksaeng-ieyo.
I am the student.
You are identifying yourself as the one.
Now imagine you're simply talking about yourself:
저는 학생이에요.
jeo-neun haksaeng-ieyo.
As for me, I'm a student.
You are introducing information about yourself. In speech you'll also hear it with no particle at all: 저 학생이에요 (jeo haksaengieyo), 민수 학생이에요 (minsu haksaengieyo).

Compare the Focus
| Sentence | Focus |
|---|---|
| 저는 학생이에요. | "Speaking of me…" — introducing your topic |
| 제가 학생이에요. | "I am the one who is a student." — identifying |
This is a beginner-friendly approximation, not a complete linguistic description — and that's fine. It gives you the right starting intuition.
Topic Markers Structure a Comparison
민수는 학생이에요.
minsu-neun haksaeng-ieyo.
Minsu is a student.
Introduces information about Minsu.
영희는 회사원이에요.
yeonghui-neun hoesawon-ieyo.
Yeonghui is an office worker.
Now 민수 → 학생 and 영희 → 회사원 are contrasted.
When 이/가 Is the Natural Choice
Suppose someone asks:
누가 학생이에요?
nuga haksaeng-ieyo?
Who is a student?
민수가 학생이에요.
minsu-ga haksaeng-ieyo.
Minsu is the student.
The question asks "who?" — so 민수 is being identified.
This is a much better way to start understanding 이/가 than memorizing "이/가 = subject."
The Important Insight
Instead of asking "Which particle translates to which English word?", ask "What information is the speaker putting in focus?"
| Particle | Beginner intuition |
|---|---|
| 은/는 | "We're talking about this…" |
| 이/가 | "This is the one/person…" |
This is a learning scaffold, not a complete grammar rule. As you encounter more examples, the model becomes more precise.
Common Mistake
Wrong approach
Memorizing "은/는 = topic, 이/가 = subject" and then mechanically selecting particles. It doesn't work well enough.
Better approach: Who/what are we talking about? → What is being identified or emphasized? → What does the surrounding context require?
One important warning: there is no single English translation for 은/는 or 이/가. Trying to translate them word-for-word is one of the fastest ways to get confused. "As for…" is a useful intuition — not a literal translation.
