(From what I can see) I guess it's...: 나 보다

A/V/N + 나 보다 indicates that you are guessing something, but unlike 것 같다, your ‘guess’ is based on direct knowledge or experience of the situation. For example:

  1. Looking out of the window at swaying trees and leaves flying around, you might say “바람이 부르나 봐요” because you are seeing the effects of the wind.
  2. When your friend tells you they are going to the UK, you might say “비가 올 것 같아요”. Although you know that it sporadically rains there, you’ve never been there, or you’re not there right now, or you’re not currently watching the weather for the UK etc.

Note: A/V/N + 나 보다 is usually said as 나 보네(요) or 나 봐(요)
