Questions & Answers about oneureun doseogwane sarami jeogeoyo.

What does each part of 오늘은 도서관에 사람이 적어요 do?

Here is the sentence piece by piece:

• 오늘은 = today
  • topic marker 은
• 도서관에 = at/in the library
  • location particle 에
• 사람이 = people / a person
  • subject marker 이
• 적어요 = are few / is few in number

So the structure is basically:

As for today, at the library, people are few.

That sounds unnatural in English, but it matches how Korean organizes the sentence.

Why is 오늘 followed by 은?

은/는 is the topic marker. It sets the background or frame for what follows.

So 오늘은 means something like:

• as for today
• today, ...
• when it comes to today

It can also add a slight contrast, like today in particular.

If you said 오늘이, that would make today the grammatical subject, which is not what this sentence is doing.

Why is it 도서관에, not 도서관에서?
