Questions & Answers about banghak iljeongeun daebubun naega jeonghaesseunikka gongyuhalge.

Why is it 방학 일정은 (topic marker) and not 방학 일정을 (object marker)?

Korean often topicalizes the object with 은/는 to set context first, then comments on it.

• 방학 일정은 대부분 내가 정했으니까 공유할게. = “As for the vacation schedule, since I decided most of it, I’ll share it.” The object is introduced as the topic and understood in the second clause.
• You could also say: 방학 일정을 내가 대부분 정했으니까 공유할게. Here, 일정을 stays as the object, with no topicalization. Both are fine; the first sounds more “as for X…” and is very natural in conversation.

What nuance does -으니까 have here? How is it different from -아서/어서 and -으니?

• -으니까 gives a reason/justification from the speaker’s viewpoint and pairs very naturally with announcements, promises, or suggestions. It can sound slightly more assertive or persuasive.
• -아서/어서 is a neutral cause/sequence link (“and so/so then”). It’s more descriptive and less about justifying a decision. With a promise/command that follows, -으니까 usually feels more natural.
• -으니 is similar to -으니까 but feels a bit more written/formal or literary.

All of these can work here, but 정했으니까 공유할게 is the most idiomatic when you’re announcing a decision to the listener.

Why is it past tense 정했으니까 instead of 정하니까?

The decision is already made, and that completed action is the reason for the next action. 정했으니까 = “since I have decided.”
정하니까 would suggest a general/habitual or simultaneous situation (“as/when I decide”), which doesn’t fit well here.

What exactly does 공유할게 mean compared with 공유할 거야, 공유할게요, and 공유하겠습니다?
