Questions & Answers about sigani eobsdamyeon yaksogeul naeillo mirwodo dwaeyo.

What nuance does -다면 add compared to -면?

• -(으)면 is the default “if/when” in everyday Korean.
• -(ㄴ/는)다면 sounds a bit more hypothetical or tentative (“if it turns out that…”), and can feel slightly more formal.
• Here, 시간이 없으면 is the most common in speech; 시간이 없다면 is perfectly correct, just a touch more “if indeed you don’t have time.”

Can I say 시간 없으면 or 시간이 없으면 instead of 시간이 없다면?

• Yes. All of these are fine.
  • 시간이 없으면: neutral, natural.
  • 시간 없으면: casual speech (dropping the subject marker).
  • 시간이 없다면: a bit more formal/hypothetical tone.

Why is -이 used on 시간? Could I use -은/는?

• 시간이 없다 treats “time” as the grammatical subject of “to not exist,” so 이/가 is natural.
• 은/는 topicalizes/contrasts, so 시간은 없다면 sounds odd unless you’re contrasting it with something else. Stick with 시간이 없다면/없으면 here.

Does 약속 mean “promise” or “appointment” here?

• In everyday contexts, 약속 commonly means an appointment/plan/meeting. With 미루다 (“postpone”), it’s clearly “appointment/plan.”
