A natural breakdown is:

• 예매처에서 = at/from the ticket seller / booking site / box office
• 지정석이 = reserved seats / assigned seats
  • subject marker 이
• 매진됐어 = sold out

So the sentence literally feels like:

At the ticket outlet, the assigned seats got sold out.

In natural English, this is usually:

The reserved seats are sold out at the ticket seller / booking site.

Depending on context, 예매처 could mean an online ticket platform, a ticket agency, or a booking outlet.

에서 often marks the place where something happens.

Here, it shows the location/source where the sold-out situation applies:

• 예매처에서 = at the booking site / through the ticket seller

It tells you where the reserved seats are sold out.

Compare:

• 학교에서 공부해. = I study at school.
• 사이트에서 팔아. = They sell it on the site.

In this sentence, 예매처에서 does not necessarily mean a physical place only; it can also mean a ticketing platform or vendor.

Because 지정석 is the grammatical subject of 매진됐어.

The sentence is saying that the reserved seats are in the state of being sold out, so 지정석이 marks what is sold out.

• 지정석이 매진됐어 = The reserved seats are sold out

Korean often marks the thing in a certain state with 이/가.

For example:

• 표가 없어. = Tickets are gone / There are no tickets.
• 물이 다 떨어졌어. = The water ran out.

So 이 here is very natural.

Because 매진되다 is the usual verb for to be sold out.

• 매진되다 = to become sold out / to be sold out

So:

• 매진됐어 = became sold out / is sold out

By contrast, 매진하다 means to sell out completely, but it is less natural when the thing itself is the subject in everyday speech.

So Korean usually says:

• 표가 매진됐어. = Tickets are sold out.
• 지정석이 매진됐어. = The reserved seats are sold out.

This is one of those cases where Korean prefers the 되다 form.

Yes, 됐어 comes from 되었어, so grammatically it is past.

But in Korean, a past form like this often describes a resulting current state:

• 매진됐어 = it became sold out → therefore it is sold out now

That is why English often uses the present:

• Reserved seats are sold out.

You could also translate it as:

• The reserved seats sold out.

But in many contexts, the intended meaning is the current result, not just the event in the past.

지정석 means assigned seat(s) or reserved seat(s), meaning seats with specific seat numbers or designated seating.

Korean nouns usually do not have to show singular vs. plural explicitly. So 지정석 can mean:

• a reserved seat
• reserved seats

In this sentence, English will usually make it plural:

• Reserved seats are sold out.

That is because sold out usually refers to the category as a whole, not one single seat.

Korean does not use articles like a and the the way English does.

So 지정석이 매진됐어 can naturally mean:

• The reserved seats are sold out
• Reserved seats are sold out
• All reserved seats are sold out

The exact English wording depends on context.

Korean often leaves this kind of information unstated when it is obvious from the situation.

매진됐어 is in the informal casual speech style.

That means it is natural when speaking to:

• friends
• family
• someone younger
• someone you are close to

More polite versions would be:

• 예매처에서 지정석이 매진됐어요.
• 예매처에서 지정석이 매진됐습니다.

So the sentence as written sounds conversational and casual.

Yes, that is a very natural implication.

Because the sentence specifically says 예매처에서, it can suggest:

• at that particular ticket seller
• on that booking platform
• through that sales channel

the reserved seats are sold out.

That leaves open the possibility that they might still be available somewhere else.

So the sentence can carry the nuance:

Reserved seats are sold out at that outlet/site.

Korean word order is flexible as long as the particles are clear.

So these are all possible:

• 예매처에서 지정석이 매진됐어.
• 지정석이 예매처에서 매진됐어.

The first version is more natural if you want to set the scene first: at the booking site...

Korean often places background information such as place, time, or context near the beginning of the sentence.

Yes, but the nuance changes.

• 지정석이 매진됐어 = simply states that reserved seats are sold out
• 지정석은 매진됐어 = as for reserved seats, they’re sold out

Using 은/는 creates contrast or topic emphasis. It can imply something like:

• Reserved seats are sold out, but maybe standing tickets are still available
• At least the reserved seats are sold out

So 이/가 is more neutral here, while 은/는 adds topic or contrast.

They are related but not identical.

• 예매처 = a place/service/vendor where you can make a reservation or book tickets

  • often broader
  • can include online ticket sites, agencies, or booking platforms

• 매표소 = ticket booth / ticket office

  • usually a physical place where tickets are sold

So 예매처에서 is a good choice if the sentence is about a booking outlet in general, especially if it could be online.

Yes, possibly.

Korean often omits information that is clear from context, such as:

• which event
• which ticket seller
• whether the speaker means now
• whether other types of seats are still available

So in a real conversation, this sentence might be understood as something like:

• At that booking site, the reserved seats are sold out.
• For this concert, reserved seats are sold out at the ticket outlet.

The omitted information is normal and does not make the sentence incomplete in Korean.
