Questions & Answers about naeil hoeui junbi ttaemune oneul mateueseo jangbwasseoyo.

Why is there no subject like 저는 in this sentence?

Korean often drops the subject when it’s obvious from context.

• (저는) 내일 회의 준비 때문에 오늘 마트에서 장봤어요. = I shopped at the mart today because I’m preparing for tomorrow’s meeting.
  Adding 저는/나는 is fine if you want emphasis or contrast, but it’s not required.

Does 내일 mean “tomorrow” or does it mean “tomorrow’s” here?

Both ideas are involved, but grammatically 내일 is acting like tomorrow’s and modifying what follows:

• 내일 회의 = tomorrow’s meeting
  So 내일 회의 준비 = preparations for tomorrow’s meeting.

What exactly does 때문에 do, and what can come before it?

-때문에 means because of / due to and it usually attaches to a noun phrase.

• 회의 준비 때문에 = because of the meeting prep / due to preparing for the meeting
  Common patterns:
• N 때문에: 일 때문에 (because of work)
• V-(으)ㅁ 때문에 (verb → noun form): 늦었음 때문에 (because of being late)
  In this sentence, 회의 준비 is treated as a noun phrase already, so 때문에 fits naturally.
