It breaks down like this:

• 앙코르가 = the encore + subject marker
• 끝나고 = ended, and/then/after
• 관객이 = the audience + subject marker
• 박수쳤어 = clapped / applauded

So grammatically, it is:

[Clause 1] 앙코르가 끝나고
[Clause 2] 관객이 박수쳤어

A very literal structure is:

The encore ended, and then the audience clapped.

Because this sentence really has two clauses, and each clause has its own subject:

1. 앙코르가 끝나고

   • subject: 앙코르
   • verb: 끝나다 (to end)

2. 관객이 박수쳤어

   • subject: 관객
   • verb: 박수치다 (to clap / applaud)

So it is completely normal to see 가/이 twice here. Each one belongs to a different clause.

Because 끝나다 is an intransitive verb. That means the thing that ends is the subject, not the object.

• 앙코르가 끝나다 = the encore ends
• not 앙코르를 끝나다

If you wanted a verb meaning to end something, you would use 끝내다, which is transitive:

• 공연을 끝냈어 = (someone) ended the performance

So in your sentence, the encore itself is what ended, which is why 가 is used.

Here, -고 connects two actions or events.

In many cases, -고 can mean:

• and
• and then
• after

In this sentence, it is most naturally understood as a sequence:

• 앙코르가 끝나고 관객이 박수쳤어
• After the encore ended, the audience clapped

So although -고 often gets taught as and, in context it can also clearly imply then/after that.

This is a very common question.

• 끝나다 = to end, to be over

  • intransitive
  • the event or thing ends by itself
  • example: 공연이 끝났어 = The performance ended

• 끝내다 = to end something, to finish something

  • transitive
  • someone actively brings something to an end
  • example: 공연을 끝냈어 = (Someone) ended the performance

In your sentence, the encore is not being ended by a stated person; it is simply over, so 끝나다 is the right verb.

Both could be possible in some contexts, but they do slightly different things.

• 관객이 marks the subject
• 관객은 marks the topic

With 관객이, the sentence simply presents the audience as the subject of the second clause:

• 관객이 박수쳤어 = The audience clapped

If you said 관객은 박수쳤어, it could sound more like:

• As for the audience, they clapped
• or it might create contrast, depending on context

So 관객이 is a straightforward, neutral choice here.

It comes from 박수치다, which means to clap or to applaud.

Breakdown:

• 박수치다 = to clap
• 박수쳤어 = clapped

The past tense form contracts like this:

• 치다
• 치 + 었어
• 쳤어

So 박수쳤어 is the casual past form of 박수치다.

Yes. That is also very common.

You may see both:

• 관객이 박수쳤어
• 관객이 박수를 쳤어

These are very close in meaning.

A simple way to think about it:

• 박수치다 treats it like a set verb: to clap
• 박수를 치다 shows the noun 박수 more separately

In everyday Korean, both are natural. Your sentence uses the compact verb form 박수치다.

The ending -어 makes the sentence casual/informal.

So 박수쳤어 is a plain, conversational way to say:

• clapped
• applauded

Compare:

• 박수쳤어 = casual
• 박수쳤어요 = polite
• 박수쳤다 = plain written/diary style
• 박수쳤습니다 = formal

So this sentence sounds like something you might say to a friend or in casual narration.

Here, 관객 is most naturally understood as the audience collectively, so it refers to a group.

Korean nouns usually do not have to show singular vs. plural the way English does. Context tells you what is meant.

So:

• 관객이 박수쳤어 = The audience clapped
• not necessarily one spectator clapped

If you specifically wanted to emphasize multiple spectators, you could sometimes use 관객들, but it is not necessary here.

Yes. 앙코르 is a loanword used in Korean for encore.

It is commonly used in music or performance contexts, just like in English. So a learner will often see it in sentences about concerts, stages, and audiences.

In this sentence, it simply refers to the encore performance segment.
