Learning the Korean Particles 은/는 vs. 이/가: A Simple Explanation

One of the most challenging aspects of learning Korean for English speakers is understanding and correctly using particles. Two pairs of particles that often cause confusion are 은/는 (eun/neun) and 이/가 (i/ga). These particles serve as subject and topic markers, which don't have direct equivalents in English. This guide will help you understand when and how to use these essential Korean particles.

Basic Rules for Choosing Between 은/는 and 이/가

When to Use 은 vs. 는

Both 은 (eun) and 는 (neun) function as topic markers, but which one you use depends on the final sound of the preceding word:

• 은 (eun): Use after words that end in a consonant
  • 책은 (chaegeun) - "as for the book"
  • 밥은 (babeun) - "as for the rice/meal"
  • 꽃은 (kkocheun) - "as for the flower"
• 는 (neun): Use after words that end in a vowel
  • 나는 (naneun) - "as for me"
  • 커피는 (keo-pineun) - "as for the coffee"
  • 학교는 (hak-gyoneun) - "as for the school"

When to Use 이 vs. 가

Similarly, 이 (i) and 가 (ga) function as subject markers, with the choice depending on the final sound of the preceding word:

• 이 (i): Use after words that end in a consonant
  • 책이 (chaegi) - "the book (as subject)"
  • 밥이 (babi) - "the rice/meal (as subject)"
  • 꽃이 (kkochi) - "the flower (as subject)"
• 가 (ga): Use after words that end in a vowel
  • 나가 (naga) - "I (as subject)"
  • 커피가 (keo-piga) - "the coffee (as subject)"
  • 학교가 (hak-gyoga) - "the school (as subject)"

Understanding the Difference Between 은/는 and 이/가

이/가 (i/ga) - The Subject Marker
