Questions & Answers about yangchihago naseo baro jayo.

What does 양치 mean here? Is it a noun or a verb?

양치 literally refers to brushing one’s teeth. By itself, it is basically a noun, and the full dictionary verb is 양치하다 = to brush one’s teeth.

So in this sentence:

• 양치하고 = brush one’s teeth and / after brushing one’s teeth

Korean often makes verbs by combining a noun with 하다.

Why is it 양치하고, not 양치해고?

Because the verb is 양치하다, and when 하다 connects to -고, it becomes 하고.

So:

• 양치하다
  • -고 → 양치하고

This is a very common pattern:

• 공부하다 → 공부하고
• 운동하다 → 운동하고
• 청소하다 → 청소하고

So 양치하고 is the normal connected form of 양치하다.
