이랑 means and / with when linking nouns in casual speech.

So 귤이랑 포도 means tangerines and grapes.

A few notes:

• 이랑 is informal/conversational.
• Common alternatives:
  • 하고 = also casual, very common
  • 와/과 = more neutral/written
• After a vowel, you use 랑; after a consonant, 이랑.

Examples:

• 사과랑 배
• 책이랑 공책
• 귤이랑 포도

In this sentence, it connects the two things that were bought.

When two nouns are connected by 이랑, the particle usually goes only once at the end of the whole noun phrase.

So:

• 귤이랑 포도를 사 왔어 = bought tangerines and grapes

Here, 포도를 carries the object marker -를, and the whole phrase 귤이랑 포도 functions as the object.

You normally do not say:

• 귤을이랑 포도를

That sounds unnatural because 이랑 is already linking the nouns together.

사 왔어 comes from 사 오다, which literally means to buy and come.

So:

• 샀어 = bought
• 사 왔어 = bought and brought (here), or bought on the way back and came

This adds a sense that the speaker went somewhere, bought the fruit, and returned with it.

Then -는데 connects that idea to what happened next:

• 귤이랑 포도를 사 왔는데 ...
  = I bought and brought tangerines and grapes, and/but ...

So 사 왔는데 gives more scene-setting than 샀는데.

In this sentence, -는데 is not just but in a simple one-word sense. It often gives:

• background information
• a setup for the next event
• sometimes a slight contrast or unexpected feeling

So here it feels like:

• I bought and brought tangerines and grapes, but/and then my older sister ate the grapes first.

Why might it feel slightly contrastive? Because there may be an implied expectation such as:

• maybe the speaker expected the tangerines to be eaten first
• maybe the speaker is mildly surprised or complaining

So -는데 often has a softer, more nuanced connection than a direct English but.

가 is the subject marker, and here it simply marks 언니 as the person who did the action.

• 언니가 포도부터 먹었어 = older sister ate the grapes first

If you said 언니는, the nuance would change:

• 언니는 포도부터 먹었어 could sound more contrastive, like as for my older sister, she ate the grapes first.

So 가 is the more straightforward choice when introducing who performed the action.

언니 means older sister, but specifically it is used by a female speaker to refer to:

• her older sister
• or sometimes an older female she is close to

If the speaker were male, he would normally say 누나 instead.

So this sentence suggests the speaker is female, unless 언니 is being used in some special social way.

부터 means starting from, from, or in many everyday cases first.

So 포도부터 먹었어 means:

• (she) ate the grapes first
• more literally, started with the grapes

This often implies an order among several choices.

Examples:

• 밥부터 먹자 = Let’s eat the rice/meal first.
• 쉬운 것부터 해 = Do the easy ones first.
• 포도부터 먹었어 = She ate the grapes first.

It does not necessarily mean she ate only grapes. It means grapes were the first thing she started with.

Yes. That is a very important nuance.

포도부터 먹었어 usually means:

• she started by eating the grapes first

It does not automatically mean:

• she ate all the grapes
• she ate only grapes
• she never ate the tangerines

It focuses on the order of actions, not the total amount eaten.

Korean word order is flexible, but some orders sound more natural in neutral speech.

언니가 포도부터 먹었어 is a normal, neutral pattern:

• subject + object/adverbial phrase + verb

You could also say:

• 언니가 먼저 포도를 먹었어
• 포도부터 언니가 먹었어

But 포도부터 언니가 먹었어 puts stronger focus on grapes first, as if contrasting with something else.

So the original sentence sounds natural and balanced, without extra emphasis.

The sentence ends in -어, which is the informal/casual speech level.

• 먹었어 = ate
• 먹었어요 = ate (polite)
• 먹었습니다 = ate (formal)

The whole sentence is casual:

• 귤이랑
• 사 왔는데
• 먹었어

So it sounds like everyday speech between friends, family, or someone close.

A polite version would be:

• 귤이랑 포도를 사 왔는데 언니가 포도부터 먹었어요.

Yes. 사 오다 is a compound verb made from:

• 사다 = to buy
• 오다 = to come

When conjugated:

• 사 오다
• 사 왔어
• 사 왔는데

It is usually written with a space because it is still understood as a verb plus auxiliary-like motion verb structure.

This pattern is common in Korean:

• 가져오다 = bring
• 먹어 보다 / 먹어보다 = try eating
• 사 오다 = buy and bring

In actual modern writing, spacing can sometimes vary with some constructions, but 사 왔는데 as written here is completely normal.

Yes. 이랑/랑 can mean either:

• and
• with

It depends on context.

Examples:

• 친구랑 영화 봤어 = I watched a movie with my friend.
• 사과랑 바나나 샀어 = I bought apples and bananas.

In your sentence, because two fruits are being listed as things that were bought, 이랑 clearly means and, not with.

Yes, but the nuance changes slightly.

Compare:

• 포도부터 먹었어 = she started with the grapes / ate the grapes first
• 포도를 먼저 먹었어 = she ate the grapes first

Both are natural, but:

• 부터 emphasizes the starting point/order
• 먼저 emphasizes first more generally

In many situations they are very similar, but 부터 often feels a bit more like choosing the first item in a sequence.

Possibly, yes.

Because of -는데, the sentence can sound like it carries a mild implication such as:

• I bought tangerines and grapes, but then my older sister ate the grapes first...
• maybe the speaker did not expect that
• maybe the speaker wanted the grapes
• maybe the speaker is just narrating, but with a slight emotional color

Korean often leaves these feelings unstated, and listeners infer them from context and tone. So the sentence can be neutral, mildly surprised, or slightly complaining depending on how it is said.
