In Korean, body parts are often treated as the subject of the condition.

So 목이 아프다 literally works like:

• 목이 = the throat
• 아프다 = hurts / is painful

That is why Korean says 목이 아프다, not usually 목을 아프다.

This is very common with body-related expressions:

• 머리가 아파요 = My head hurts / I have a headache
• 배가 아파요 = My stomach hurts
• 눈이 아파요 = My eyes hurt

Even though English often uses my, Korean often leaves that understood from context.

Korean often omits obvious information, especially things like my, your, or his/her, when the context makes it clear.

So 목이 아프면 naturally means something like if my throat hurts or when your throat hurts, depending on context.

In everyday Korean, saying 내 목이 아프면 can sound a bit more explicit than necessary unless you really want to emphasize my throat specifically.

This is very normal with body parts and personal states:

• 배가 고파요 = I’m hungry
• 머리가 아파요 = I have a headache
• 다리가 아파요 = My leg hurts

-면 means if or when, depending on context.

So:

• 아프다 = to hurt / to be painful
• 아프면 = if it hurts / when it hurts

In this sentence, 목이 아프면 sets up a condition: if the throat hurts, then the next action happens.

This form is very common for conditionals:

• 비가 오면 = if it rains
• 시간이 있으면 = if I have time
• 배고프면 = if you’re hungry

It does not automatically mean a one-time event or a general truth; the exact nuance depends on context.

친구가 marks friend as the subject of the second part of the sentence.

The action 끓여 줘요 is something the friend does, so 친구가 identifies who performs that action.

Structure-wise, the sentence is basically:

• 목이 아프면 = if my throat hurts
• 친구가 = my friend
• 따뜻한 차를 = warm tea
• 끓여 줘요 = makes/boils it for me

Using 가 here is natural because it introduces the doer of the action.

Yes, it could, but the nuance changes.

• 친구가 focuses more on who does it
• 친구는 would make friend more of the topic, often with a contrastive or descriptive feel

Compare:

• 친구가 따뜻한 차를 끓여 줘요
  = My friend makes me warm tea.
  This sounds like you are identifying the friend as the person who does this.

• 친구는 따뜻한 차를 끓여 줘요
  = As for my friend, they make me warm tea.
  This can sound more like you are talking about what your friend does, possibly in contrast with someone else.

For a simple sentence like this, 친구가 is very natural.

주다 after another verb often adds the idea of doing something for someone.

So:

• 끓여요 = boils / makes
• 끓여 줘요 = boils/makes it for someone

In this sentence, 끓여 줘요 means the friend is making warm tea for the speaker.

This is called the benefactive use of 주다.

Examples:

• 문을 열어 줘요 = opens the door for me/someone
• 숙제를 도와줘요 = helps me/someone with homework
• 밥을 해 줘요 = cooks for me/someone

So 주다 adds kindness, help, or benefit.

Yes. Both are seen.

• 끓여 줘요 is the more standard spaced form
• 끓여줘요 is very common in everyday writing and messaging

The same thing happens with many verb + 주다 combinations:

• 도와 줘요 / 도와줘요
• 사 줘요 / 사줘요
• 알려 줘요 / 알려줘요

In careful writing, spacing is often preferred, but in casual writing, the 붙여쓰기 form is extremely common.

Because 차 is the object of the verb 끓여 줘요.

The tea is the thing being made/boiled, so it takes the object marker 를.

• 차를 끓여요 = boil/make tea
• 물을 끓여요 = boil water
• 라면을 끓여요 = cook ramen

So in this sentence:

• 따뜻한 차를 = warm tea + object marker

따뜻하다 is a descriptive verb, often called an adjective in English-style explanations. When it comes directly before a noun, it changes form.

So:

• dictionary form: 따뜻하다 = to be warm
• noun-modifying form: 따뜻한 = warm

That is why you get:

• 따뜻한 차 = warm tea
• 따뜻한 물 = warm water
• 따뜻한 날씨 = warm weather

This pattern is very common with 하다 descriptive verbs:

• 조용하다 → 조용한 방 = a quiet room
• 중요하다 → 중요한 문제 = an important problem
• 이상하다 → 이상한 사람 = a strange person

Yes, 끓이다 literally means to boil, but in Korean it is also commonly used for making things like tea, soup, ramen, and so on.

So for Korean learners, it is useful to think of it as:

• literally: to boil
• naturally in context: to make / prepare by boiling

Examples:

• 차를 끓이다 = make tea
• 라면을 끓이다 = cook ramen
• 국을 끓이다 = make soup

So the Korean verb may sound more specific than the English translation.

Yes, 끓여 is a hard form for many learners.

It comes from 끓이다. In actual pronunciation, it is commonly said close to 끄려.

A helpful rough guide:

• 끓이다 → often sounds close to 끄리다
• 끓여요 → often sounds close to 끄려요

The spelling keeps the original verb form, but the pronunciation becomes simpler in real speech.

You do not need to pronounce every written consonant fully and separately. Listening practice is especially helpful for this word.

By itself, the sentence does not strictly specify whether it is a habitual action or a one-time event. Context decides that.

It could mean:

• When my throat hurts, my friend makes me warm tea
  = a habitual or usual situation

or

• If my throat hurts, my friend will make me warm tea
  = a possible future situation

Because Korean often leaves tense and frequency more open than English, you rely on context, time words, or the conversation situation.

If you wanted to make habitual meaning clearer, you could add something like:

• 목이 아플 때마다 = whenever my throat hurts

If you wanted a more clearly future meaning, context or additional wording could help.

In a sentence like this, it helps to think of it as having two clauses.

1. 목이 아프면

   • subject: 목
   • predicate: 아프다

2. 친구가 따뜻한 차를 끓여 줘요

   • subject: 친구
   • object: 따뜻한 차
   • verb: 끓여 줘요

So both 목 and 친구 are subjects, but each belongs to a different part of the sentence.

This is very common in Korean complex sentences.

It depends on what kind of tea you mean.

• 차를 끓여요 suggests boiling/preparing warm tea, and it feels natural when the tea is made with hot water on the stove or as part of a soothing, homey action.
• 차를 타요 means something like make tea by mixing/preparing it, often for instant drinks, powdered drinks, or tea made by pouring hot water.

So both can be natural in different situations, but 끓여 줘요 gives a comforting feeling and fits well with the situation of someone having a sore throat.

The ending 줘요 is part of the polite informal style, often called the 해요체.

It is very common in everyday Korean because it sounds polite without being overly formal.

Compare:

• 끓여 줘요 = polite everyday style
• 끓여 줍니다 = more formal
• 끓여 줘 = casual, used with close friends or younger people

So this sentence is in a natural, conversational polite form.
