Topic and subject particles

은/는 and 이/가 help Korean show what the sentence is about and what is specifically being identified or highlighted.

Examples

Pattern

topic + subject + adjective/verb

How it works

은/는 and 이/가 help Korean show what the sentence is about and what is specifically being identified or highlighted. This pattern typically appears as topic + subject + adjective/verb and becomes easier when you meet it again in short, readable examples.

What to notice

  • 은/는 often frames the topic or contrast.
  • 이/가 often marks the subject more directly or brings in new information.

Why it matters

Start with polite identity and the particles that structure the sentence.

Use in context

These particles matter so much in Korean that they deserve focused side-by-side explanation early.
