Questions & Answers about mogi apeumyeon mureul manhi masyeoyo.

Why is it 목이 and not 목은/목을?

In this sentence, 목(이) 아프다 is a fixed/very common way to say to have a sore throat (literally, the throat hurts).

• 목이 uses the subject marker -이/가 because 목 is what is hurting.
• 목은 (topic marker) is possible if you’re contrasting: As for my throat, it hurts (but something else is fine).
• 목을 would mark 목 as an object, but 아프다 doesn’t normally take a direct object in this meaning.

What does -면 mean here, and how is it formed?

-면 means if/when (a conditional).
It attaches to a verb/adjective stem:

• 아프다 → stem 아프-
  • -면 → 아프면 = if it hurts / if you’re sick (in that way)

So 목이 아프면 = if your throat hurts / if you have a sore throat.

Does 목이 아프면 mean if my throat hurts or if your throat hurts? Who is the subject?

It can be my/your/their depending on context. Korean often omits pronouns when they’re obvious.
So this can mean:

• If (your) throat hurts, drink lots of water.
• If (my) throat hurts, I drink lots of water. (less likely with 마셔요 unless context supports it)

In everyday advice, it’s usually understood as your throat.
