초연 means the premiere or the first performance of a play, musical, concert piece, or other staged work.

• 초 = first, initial
• 연 comes from a word related to performance/showing

So 초연 전에 means before the premiere.

전에 means before.

In Korean, it is often attached after a noun to mean before that noun/event:

• 공연 전에 = before the performance
• 식사 전에 = before the meal
• 초연 전에 = before the premiere

So 초연 전에 literally means before the premiere.

관객석 means the audience seating area, the seats for the audience, or simply the audience section in a theater or venue.

It is made of:

• 관객 = audience, spectators
• 석 = seat

So this does not mean the audience members themselves, but rather the seating area where they sit.

을 is the object particle. It marks 관객석 as the thing being checked.

• 관객석을 확인했어 = checked the audience seating area

The object particle appears as:

• 을 after a consonant
• 를 after a vowel

Since 관객석 ends in ㄱ, it takes 을.

확인했어 means checked, confirmed, or inspected, depending on context.

It comes from:

• 확인하다 = to check / confirm
• 확인했어 = did check / checked

Breakdown:

• 확인하- = the verb stem of 확인하다
• -였- / -았- / -었- = past tense element
• -어 = informal polite-neutral ending used in casual speech

Because 하다 verbs change in a special way:

• 확인하다 → 확인했어

So the whole verb means checked in a casual style.

했어 is a casual, non-formal sentence ending. It is commonly used:

• with friends
• with people younger than you
• in diaries
• in conversational narration
• in informal written content

A more formal version would be:

• 초연 전에 관객석을 확인했습니다.

Both mean the same thing, but the tone is different:

• 확인했어 = casual
• 확인했습니다 = formal/polite

Yes, the subject is omitted, and that is very normal in Korean.

초연 전에 관객석을 확인했어 could mean:

• I checked the audience seating before the premiere.
• We checked the audience seating before the premiere.
• He/She checked the audience seating before the premiere.

The subject is understood from context. Korean often leaves out subjects when they are already obvious.

Korean word order is flexible, but it often places time expressions early in the sentence.

So:

• 초연 전에 = before the premiere
• 관객석을 = the audience seating area
• 확인했어 = checked

This follows a very common Korean pattern:

time + object + verb

A natural English translation is: I checked the audience seating before the premiere.

Even though the Korean order is different, that is completely normal.

It can mean both, depending on context.

확인하다 often means:

• to check
• to confirm
• to verify

In this sentence, checked is probably the most natural translation, because 관객석 is a physical place/area. It suggests someone inspected or looked over the seating area before the premiere.

If the object were something more factual or informational, confirm might sound better.

For example:

• 예약을 확인했어 = I confirmed the reservation / I checked the reservation
• 시간을 확인했어 = I checked the time
• 관객석을 확인했어 = I checked the audience seating area

Good question. Although 전 can relate to before/front in some contexts, 전에 after a noun here clearly means before in time, not in front of physically.

So:

• 초연 전에 = before the premiere

If you wanted to say in front of something physically, Korean would usually use a different expression such as:

• 앞에 = in front of

So there is no ambiguity here: this sentence is about time, not location.

The dictionary-style version is:

초연 전에 관객석을 확인하다.

That is the plain dictionary form of the verb. In actual conversation, you would usually change the ending depending on speech level:

• 확인했어 = casual
• 확인했어요 = polite
• 확인했습니다 = formal

A natural pronunciation is roughly:

초연 전에 관객서글 화긴해써

A few useful pronunciation notes:

• 관객석을 often sounds like 관객서글 in connected speech
• 확인 is pronounced more like 화긴
• 했어 sounds like 해써

So learners may hear something a bit different from the spelling, which is normal in Korean pronunciation.
