Simply Learn Korean

Korean particles 은/는 and 이/가 are among the most challenging concepts for Korean learners. In English, both often translate as simple subject markers, but in Korean, they carry very different nuances and functions.

Here is a simple, clear guide to master them once and for all!

1. 은/는 = Topic Marker (주제격 조사)

• 은 after a consonant (e.g., 책은)
• 는 after a vowel (e.g., 저는)

It introduces the main topic—what or who the sentence is about.

💡 Think: “As for…” or “Speaking of…”

Examples:

• 저는 학생이에요.(As for me, I am a student. / I am a student.)
• 오늘은 바빠요.(As for today, I’m busy. / Today I’m busy.)

2. 이/가 = Subject Marker (주격 조사)

• 이 after a consonant (e.g., 물이)
• 가 after a vowel (e.g., 고양이가)

It marks the specific subject that performs the action or exists. It focuses on who or what is doing something.

💡 Think: “Who or what is doing it?” or answering a question like “Who is it?”

Examples:

• 고양이가 자요.(The cat is sleeping.)
• 비가 와요.(Rain is falling. / It’s raining.)

3. Key Nuance Differences (뉘앙스 비교)

🔹 Example 1: 저 (I/Me)

• 저는 학생이에요.(As for me, I’m a student.) → General statement about yourself.
• 제가 학생이에요.(I am the student.) → Emphasizes “I” (e.g., “Who here is a student?” “I am!”).

🔹 Example 2: 사과 (Apple)

• 사과는 맛있어요.(Apples are tasty.) → General statement or comparing apples to other fruits.
• 사과가 맛있어요.(This apple is tasty.) → Focusing on a specific apple you are eating right now.
