Learn Hardcore Korean: nae mesiji ttaemune ohaega saenggin geos gata. - It seems a misunderstanding happened because of my message.

때문에 after a noun means “because of / due to [noun]”. So 내 메시지 때문에 = “because of my message.”
-기 때문에 attaches to a verb/adjective to make “because (someone) does/ed/is ….” For example:
- 메시지를 보냈기 때문에 오해가 생겼어요. = “Because I sent a message, a misunderstanding occurred.”
With a noun cause, use N + 때문에. With a verb/adjective cause, use V/A + 기 때문에.
Colloquial alternative: -아서/어서 for verb clauses (less formal, often sounds more neutral than -기 때문에).

Why is it 오해가 생기다 instead of 오해하다?

오해가 생기다 literally “a misunderstanding arises/occurs” (the misunderstanding itself appears). It’s neutral and common when describing the situation.
오해하다 = “to misunderstand (something/someone).” It assigns a subject who is doing the misunderstanding.
Choose based on focus:
- Situation-focused: 오해가 생겼어요. (A misunderstanding happened.)
- Agent-focused: 제가 오해했어요. (I misunderstood.)

Why is the subject marker 가 used on 오해 (as in 오해가)? Could it be 오해는?

오해가 marks “a misunderstanding” as new information (“there is/was a misunderstanding”).
오해는 topicalizes it, contrasting or highlighting it (“As for the misunderstanding…”). You’d use 는 when contrasting with something else or continuing a known topic.
Here, 가 sounds natural because we’re presenting the occurrence as the main new event.

What does 생긴 것 같아 mean grammatically?

- 생기는 것 같아: “seems to be arising (now/soon).”
- 생겼던 것 같아: “seems it had arisen (at some point in the past).”
