🧩 Understanding Korean Particles: 은/는, 이/가, 을/를 Explained

If you’ve just started learning Korean, chances are you’ve run into these small but powerful words: 은/는, 이/가, and 을/를.
They’re called particles (조사), and they attach to nouns to show what role each word plays in a sentence. Think of them as Korean sentence glue! 🧷
Let’s break down each one so you can start using them naturally.
1️⃣ 은/는 – The Topic Particle
Used to introduce or emphasize the topic of a sentence.
-
은 → after consonants
-
는 → after vowels
Examples:
-
저는 학생이에요. (jeoneun haksaeng-ieyo) → As for me, I’m a student.
-
이 음식은 맛있어요. (i eumsig-eun masisseoyo) → This food, it's delicious.
📌 Tip: 은/는 often shows contrast or general statements.
→ 오늘은 비가 와요. (Today, it’s raining — but not yesterday.)
2️⃣ 이/가 – The Subject Particle
Used to mark the subject that is doing something or existing.
-
이 → after consonants
-
가 → after vowels
Examples:
-
고양이가 귀여워요. (goyangi-ga gwiyeowoyo) → The cat is cute.
-
친구가 왔어요. (chingu-ga wasseoyo) → A friend came.
📌 Tip: 이/가 puts focus on what is new or important.
→ 누가 했어요? → 제가 했어요! (Who did it? → I did it!)
3️⃣ 을/를 – The Object Particle
Marks the object that receives an action.
-
을 → after consonants
-
를 → after vowels
Examples:
-
밥을 먹어요. (bap-eul meogeoyo) → I eat rice.
-
영화를 봐요. (yeonghwa-reul bwayo) → I watch a movie.
📌 Tip: 을/를 answers “what” is being acted on.
→ 저는 커피를 마셔요. (I drink coffee.)
⚖️ 은/는 vs. 이/가: What’s the Difference?
Let’s compare:
Sentence | Meaning / Emphasis |
---|---|
고양이는 귀여워요. | As for the cat, it’s cute. (general) |
고양이가 귀여워요. | The cat is cute. (specific) |
Use 은/는 for contrast or known topics.
Use 이/가 for new information or the doer of the verb.
