Questions & Answers about syawohago naseo seuteurechingeul haeyo.

What does -고 나서 mean and how is it used?

“Verb stem + -고 나서” means “after doing (that verb)….” To form it, drop -다 from the dictionary form, add -고, then attach 나서.
Example: 샤워하다 → 샤워하 + -고 나서 = 샤워하고 나서 (“after showering”).

Can I say 샤워한 후에 instead of 샤워하고 나서?

Yes. Both mean “after showering.”

• 샤워한 후에 uses the noun form + Sino-Korean 후(後)
  • particle -에 and is slightly more formal or written.
• 샤워하고 나서 is more conversational.

Why is there no subject mentioned in the sentence?

Korean often drops the subject when it’s clear from context. Here, the speaker (I) or the listener (you) is understood. It would feel redundant to say 저는 or 나는 if the context is obvious.

Why is it 스트레칭을 해요 instead of just 스트레칭해요?

Both are grammatically correct.

• 스트레칭을 해요 treats 스트레칭 as a noun and uses the object marker 을 with 하다 (“to do a stretching”).
• 스트레칭해요 treats 스트레칭하다 as a single verb.
  Using 을 해요 can sound a bit more precise; dropping 을 is a common shortcut.
