Questions & Answers about bogoseoreul imeillo jalmos bonae beoryeosseoyo.
What does 보고서를 mean grammatically, and why is -를 attached?
보고서 = report.
-를 is the object particle (attached after a noun ending in a vowel), marking 보고서 as the direct object of the verb 보내다 (to send).
So 보고서를 보내다 = to send a report.
Why is it 이메일로 and not 이메일을?
-로 marks the means/method/channel: by / via.
So 이메일로 보내다 = to send via email.
If you wrote 이메일을, you’d be treating email as the object (like send an email), which would shift the meaning. Here the object is 보고서, so email is the method: 이메일로.
What role does 잘못 play in the sentence?
잘못 is an adverb meaning wrongly / by mistake. It modifies 보내다 (send), describing how the sending happened:
잘못 보내다 = to send incorrectly / to send to the wrong place/person by mistake.
