Korean 은/는 (eun/neun) and 이/가 (i/ga) confuse everyone—because English doesn’t mark “topic” and “subject” the same way.

This page skips the full academic treatment and gives feelings + patterns you can use in your first months.

Use our Korean basics hub, drill the Korean beginner mixed quiz and Korean polite phrases quiz, and keep 80/20 Korean in mind—you don’t need perfect particles on day one.

은/는 — “as for X…” (topic / frame)

Think: setting the stage for what you’re about to say.

  • 저는 학생이에요. (Jeoneun haksaeng-ieyo.) — “As for me, I’m a student.”
  • 오늘은 바빠요. (Oneureun bappayo.) — “Today, (I’m) busy.” (today is the frame)

Contrast often uses 은/는:

  • 커피는 좋아해요. 차는 안 마셔요. — “I like coffee. I don’t drink tea.” (coffee vs tea as topics)

이/가 — “this thing does / is…” (subject / identifier)

Think: which thing is doing the action or has the property—often new information or answers “who/what.”

  • 누가 왔어요? (Nuga wasseoyo?) — “Who came?”
  • 민수가 왔어요. (Minsuga wasseoyo.) — “Minsu came.”

Existence / appearance patterns often pair with 이/가:

  • 사람이 있어요. (Sarami isseoyo.) — “There is a person.”

One cheat line

If you’re introducing the sentence’s “main character” for the comment that follows, 은/는 is common.
If you’re pinning the subject inside the scene (especially with verbs/adjectives that feel “happening to” someone), 이/가 shows up a lot.

When stuck: listen for what natives use in the same situation—imitation beats overthinking early on.

Don’t fight native usage on day three

Learners sometimes freeze trying to pick the “correct” particle. Understand the vibe, then absorb through input.

Your everyday phrase and ordering posts are full of real -요 lines—notice particles there without memorizing rules first.

Japanese learners: rough parallel

If you know Japanese は / が, the topic vs subject intuition overlaps—but not 1:1.
