Questions & Answers about oryu ttaemune meire cheombupaireul neohji moshaesseo.

What does 오류 때문에 mean, and how is 때문에 used?

때문에 means because of or due to.

So 오류 때문에 = because of an error / due to an error.

It is commonly attached to a noun:

• 비 때문에 = because of the rain
• 일 때문에 = because of work
• 오류 때문에 = because of an error

It often sounds a bit more formal or objective than some other cause expressions like -아서/어서.

In this sentence, 오류 때문에 tells you the reason the speaker could not attach the file.

Why is it 메일에 and not 메일을?

Here, 에 marks the place or target that something is put into.

• 메일에 첨부파일을 넣다 = to put an attached file into an email

So:

• 메일에 = into the email
• 첨부파일을 = the attached file
• 넣다 = to put in

If you used 메일을, that would make mail/email the direct object, which does not fit this verb as naturally here.

You can think of the structure as:

[place/container]에 [object]을/를 넣다
= put [object] into [place/container]

Examples:

• 가방에 책을 넣었어. = I put a book in the bag.
• 메일에 첨부파일을 넣었어. = I put an attached file in the email.

Why does the sentence use 첨부파일을 넣다 instead of a verb like 첨부하다?
