Questions & Answers about susul ttaemune oneul sane mos ga.
때문에 means because of or due to.
In this sentence, 수술 때문에 means because of surgery or because of the operation.
A very useful pattern is:
- noun + 때문에 = because of + noun
Examples:
- 비 때문에 못 가. = I can’t go because of the rain.
- 일 때문에 바빠. = I’m busy because of work.
With this sentence, 수술 때문에 오늘 산에 못 가. gives the reason first, then the result.
Korean often leaves out the subject when it is clear from context.
So 수술 때문에 오늘 산에 못 가. could mean:
- I can’t go to the mountain today because of surgery
- We can’t go...
- He/She can’t go...
In real conversation, the listener usually already knows who is being talked about, so Korean does not need to say the subject as often as English does.
If you wanted to include it, you could say:
- 저는 수술 때문에 오늘 산에 못 가. = As for me, I can’t go today because of surgery.
But in everyday Korean, leaving it out is very natural.
