What Are Subject Marking Particles in Korean?
In Korean, subject marking particles are used to indicate the subject of a sentence—the person or thing performing the action. Unlike English, where word order largely determines the subject, Korean relies on these particles to clarify who or what the sentence is about. The two main subject particles are “이” (i) and “가” (ga).
When to Use “이” (i) and “가” (ga)
The choice between “이” and “가” depends on the final sound of the preceding noun:
- “이” (i): Used after nouns ending with a consonant.
- “가” (ga): Used after nouns ending with a vowel.
For example:
- 책 이 있다. (chaeki itda) – There is a book. [책 (book) ends with a consonant]
- 사과 가 맛있다. (sagwaga masitda) – The apple is delicious. [사과 (apple) ends with a vowel]
Understanding the Function of Subject Particles
Subject particles do more than just mark the subject—they can also emphasize or introduce new information. Here’s how:
1. Introducing New Subjects
When you mention something for the first time in a conversation, use “이/가” to highlight it as new information.
Example: 고양이가 집에 있어요. (The cat is at home.)
2. Emphasizing the Subject
If you want to stress the subject or distinguish it from others, “이/가” is the right choice.
Example: 누가 했어요? 제가 했어요. (Who did it? I did it.)
Comparison with Topic Marking Particles: “은/는”
Many learners confuse “이/가” with the topic markers “은/는.” While both are used to indicate the subject or topic, they serve different functions:
- 이/가 focuses on identifying the subject or introducing new information.
- 은/는 is used to talk about known topics or to contrast information.
For example:
- 오늘 비가 와요. (It is rain that is coming today.) [Emphasizing the rain]
- 오늘은 비가 와요. (As for today, it is rain that is coming.) [Contrasting today with other days]
Common Mistakes and How to Avoid Them
- Forgetting to use a particle: Every subject requires a particle. Omitting it can make sentences unclear.
- Using the wrong particle after the noun: Remember the rule: “이” for consonant endings, “가” for vowel endings.
- Mixing up subject and topic particles: Use “이/가” for new or emphasized subjects, and “은/는” for general topics.
