Here, 그 most naturally means that.

So 그 부부 is that couple.

In real Korean, 그 can sometimes feel a little broader than English that, and depending on context it may be translated more naturally as the. But in a basic sentence like this, that couple is the clearest way to understand it.

부부 means a married couple or husband and wife as a pair.

So:

• 부부 = couple, married pair

It does not just mean any romantic couple. It specifically refers to two people who are married.

의 marks possession, similar to English 's or of.

So:

• 부부의 딸 = the couple’s daughter
• literally, couple + possessive + daughter

You can think of it as:

• A의 B = B of A / A’s B

So:

• 그 부부의 딸 = that couple’s daughter

은 is the topic marker.

So 딸은 means something like:

• as for the daughter...
• the daughter, ...

This makes 딸 the topic of the sentence.

If you used 딸이, the sentence would feel a bit more like you are specifically identifying or emphasizing the daughter as the subject. With 딸은, the sentence sounds like you are introducing the daughter as the thing you are talking about.

In many beginner sentences, 은/는 is used when the speaker is making a general statement about something already known in the conversation.

아직 means still here.

So:

• 아직 어려요 = is still young

In other contexts, 아직 can also mean yet, especially in negative sentences.

For example:

• 아직 안 갔어요 = I haven’t gone yet

But in this sentence, the natural meaning is still.

Good question — there are two different words that can look similar:

• 어리다 → 어려요 = to be young
• 어렵다 → 어려워요 = to be difficult

In this sentence, 어려요 comes from 어리다, so it means is young.

That is why context matters:

• 아직 어려요 = is still young
• 어려워요 would be is difficult

This is because of how Korean verb/adjective endings combine.

• dictionary form: 어리다
• stem: 어리-
• polite ending: -어요

So:

• 어리 + 어요 → 어리어요
• this contracts to 어려요

This kind of contraction is very common in Korean.

So 어려요 is just the normal polite present-tense form of 어리다.

Because 어려요 already works as the predicate.

In Korean, descriptive words like 어리다 function like adjectives, but they behave more like verbs in a sentence. That means they can end the sentence by themselves.

So:

• 딸은 아직 어려요 = The daughter is still young

Korean does not need a separate verb like English is here.

This is very normal:

• 커요 = is big
• 작아요 = is small
• 예뻐요 = is pretty
• 어려요 = is young

A very literal breakdown is:

• 그 = that
• 부부의 = couple’s
• 딸은 = daughter + topic marker
• 아직 = still
• 어려요 = is young

So the structure is:

That couple’s daughter, still young.

A natural English translation adds is: That couple’s daughter is still young.

This shows a common Korean pattern:

• topic first
• descriptive ending at the end

의 has a few pronunciations in Korean, which can confuse learners.

In careful pronunciation, 의 is often taught as ui.
But in everyday speech, when it marks possession, it is very often pronounced more like 에.

So 부부의 may sound like:

• 부부의 in careful speech
• 부부에 in natural conversation

Both are normal to know about. As a learner, you should recognize both when listening.

Yes, depending on context.

그 부부의 딸 is literally that couple’s daughter, but in natural English, if the couple has already been mentioned, it could be translated as their daughter.

Korean often keeps noun phrases where English might switch to a pronoun.

So in context:

• 그 부부의 딸은 아직 어려요 could naturally be understood as
  • That couple’s daughter is still young
  • Their daughter is still young
