Questions & Answers about oneureun mogi apaseo noraereul an bulleoyo.

Why is 오늘 followed by 은/는 (오늘은) instead of 이/가?

은/는 marks the topic (what the sentence is about) and often adds a sense of contrast or “as for…”.
So 오늘은 is like “As for today, … (I’m not singing).” It can also imply “(though maybe other days are different).”
오늘이 would mark 오늘 as the grammatical subject, which is less natural here unless you’re saying something like “Today is (the day when…)”.

What does 목이 mean, and why is it 이/가 here (목이 아파서)?

목 means “neck” or “throat.” In this context it usually means “throat/voice.”
이/가 marks the subject of the descriptive verb 아프다 (“to hurt / be sore”).
So 목이 아프다 literally means “The throat hurts” → “My throat is sore.”

Why is the reason expressed with -아/어서 (아파서)?

-아/어서 connects two clauses and commonly means “because / so” in everyday speech.
목이 아파서 = “because (my) throat hurts / is sore,” leading to the result in the next clause.

Is -아/어서 always “because”? Can it also mean “and then”?

It can do both depending on context:
