Questions & Answers about jeoneun oneul gyeongcharege gyotongsagoreul singohaesseoyo.

Why is it 저는 here? Why not 나는 or 제가?

저는 is 저 + 는.

• 저 = the humble/polite way to say I
• 는 = the topic marker

So 저는 means something like as for me or speaking of me.

Why not the others?

• 나는 uses 나, which is the plain/casual I. It is not appropriate in a polite sentence ending in -어요 unless the overall speech style is mixed on purpose.
• 제가 uses the subject marker 가. It often sounds more like I as the one who did it, with a bit more focus on the subject.

In this sentence, 저는 is a very natural choice if you are simply talking about what you did today.

Why can 오늘 be used with a past-tense verb like 신고했어요?

Because 오늘 just tells you when the action happened: today.

The verb 신고했어요 is past tense, so the sentence means the reporting happened earlier today.

This works the same way in English:

• Today I reported it
• Today I ate breakfast at 8
• Today I met the police

So there is no contradiction. 오늘 gives the time frame, and 했어요 shows the action is already completed.

What does 경찰에게 mean, and what does -에게 do?
