예매처 means a ticket vendor, ticket outlet, or booking site/place where tickets are sold.

It can refer to:

• a physical ticket office
• an online ticketing website
• a company/platform that handles reservations

So in this sentence, 예매처에서 means at/from the ticket seller or booking site.

에서 often marks the place where an action happens.

In 예매처에서 취소표를 찾았어, the action of finding happened at/on the ticketing source, so 에서 is natural.

Compare:

• 집에서 공부했어. = I studied at home.
• 인터넷에서 찾았어. = I found it on the internet.
• 예매처에서 찾았어. = I found it at/on the ticketing site/outlet.

Here, 에서 is not just simple location like in or at; it marks the location connected to the action.

취소표 literally means a canceled ticket or, more naturally in English, a ticket that became available because someone canceled.

It is made up of:

• 취소 = cancellation
• 표 = ticket

So 취소표 usually refers to a ticket that was previously booked but then released back for sale.

를 is the object marker. It marks 취소표 as the thing that was found.

So:

• 취소표를 찾았어 = found a canceled ticket / found a released ticket

If you remove 를, the sentence becomes less standard in neutral written Korean. In conversation, particles are sometimes dropped, but here 를 clearly shows that 취소표 is the direct object.

It can relate to both ideas depending on context, which is why learners often get confused.

찾다 can mean:

• to look for
• to find

In this sentence, because it is 찾았어 in the past tense and the meaning is already given as a successful result, it means found.

Examples:

• 취소표를 찾고 있어. = I’m looking for a canceled ticket.
• 취소표를 찾았어. = I found a canceled ticket.

So here it expresses the result, not just the search.

찾았어 is:

• 찾다 = to find / look for
• 찾았어 = found / looked for

The -았어 / -었어 ending is:

1. past tense
2. informal, casual speech

So 찾았어 is something you would say to:

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

More polite versions:

• 찾았어요 = polite
• 찾았습니다 = formal

Yes. Korean often omits the subject when it is understood from context.

So 예매처에서 취소표를 찾았어 could mean:

• I found a canceled ticket at the ticketing site
• We found a canceled ticket at the ticketing site
• He/She found a canceled ticket at the ticketing site

In many real conversations, Korean does not state I or we unless it is necessary.

The sentence follows a very common Korean pattern:

place + object + verb

So:

• 예매처에서 = at/from the ticketing place/site
• 취소표를 = a canceled ticket
• 찾았어 = found

Korean usually puts the verb at the end, unlike English.

A very literal breakdown would be:

• At the ticketing site, a canceled ticket found.

A natural English translation is:

• I found a canceled ticket at the booking site.

Yes. That is a very natural interpretation, especially with something like 예매처.

Because 예매처 can be an online platform or seller, 예매처에서 can mean:

• at the ticket outlet
• on the booking site
• through the ticket vendor

So the exact English wording depends on context:

• If it is a website: I found a canceled ticket on the booking site.
• If it is a seller/source: I found a canceled ticket through the ticket vendor.

표 just means ticket.

취소표 is more specific: it is a ticket made available again because of a cancellation.

Compare:

• 표를 샀어. = I bought a ticket.
• 취소표를 찾았어. = I found a canceled/released ticket.

So 취소표 gives extra information about the kind of ticket.

A common polite version is:

예매처에서 취소표를 찾았어요.

This means the same thing, but it is more appropriate for:

• strangers
• coworkers
• people older than you
• everyday polite conversation

A formal style would be:

• 예매처에서 취소표를 찾았습니다.

The original 찾았어 is casual.
