It is always used with negative sentences.

Meaning:

• only (in a restrictive sense)
• nothing but

  (There is only 10 minutes.)

👉 All sentences end in negative forms like 없어요 / 안 먹어요.

2. What Does 만 Mean in Korean Grammar?

“만” is a neutral grammar particle meaning “only” or “just.”

Unlike “밖에,” it does NOT require negative sentences.

It is widely used in Korean limitation grammar and is part of any beginner Korean particle guide.
