Questions & Answers about jeoneun beolsseo sugang sincheongeul haesseoyo.

Why is 저는 used here instead of 제가?

The particle -은 in 저는 marks 저 (“I”) as the topic of the sentence, setting the context “as for me….”
If you used 제가 (subject marker -가), you’d be focusing on “I” as the one who did it, often implying contrast (e.g. “I [and not someone else] already registered”).
In everyday statements like this, 저는 is more natural for simply saying “I have already registered.”

What’s the function of 벌써, and how does it differ from 이미?

• 벌써 means “already,” often with a nuance of surprise or that something happened earlier than expected.
• 이미 also means “already,” but is more neutral (no surprise implied).
  Examples:
  • 저는 벌써 수강 신청을 했어요.
  (“I already registered [and I’m a bit surprised I’m done so soon].”)
  • 저는 이미 수강 신청을 했어요.
  (“I have already registered,” stated as a neutral fact.)

Where should 벌써 be placed in a Korean sentence?

Adverbs like 벌써 typically sit close to the verb they modify. Common positions are:

1. Right before the verb:
   저는 수강 신청을 벌써 했어요.
2. After the topic:
   저는 벌써 수강 신청을 했어요.
3. At the very front (for emphasis):
   벌써, 저는 수강 신청을 했어요.
   Korean word order is fairly flexible, but adverbs usually hover near the predicate.

Why is there -을 after 수강 신청?
