Questions & Answers about oneureun chuunikka changmuneul dadayo.
은 is the topic marker, so 오늘은 means something like as for today or today, ....
In this sentence, 오늘 is setting the scene or topic:
- 오늘은 = today / as for today
If you used 오늘이, that would mark today as the grammatical subject, which would sound less natural here.
So:
- 오늘은 추우니까... = Since it’s cold today...
The sentence is not really focusing on today as the subject; it is using today as the topic.
-니까 means because or since.
So:
- 추우니까 = because it is cold / since it is cold
In this sentence:
- 오늘은 추우니까 창문을 닫아요.
- Since it’s cold today, [I’m / let’s / please] close the window.
A very important point: -니까 often gives a reason that leads to a suggestion, command, or decision. That makes it very natural here.
