-이/가 is the subject marker in Korean. Here, 직원 means employee or staff member, and 직원이 means the employee/staff member as the one doing the action.

So in this sentence:

• 직원이 = the employee is the subject
• 제 예약을 = my reservation is the object
• 확인해 줬어요 = confirmed it for me

A learner may also wonder why this is not 직원은. Using -은/는 would add more of a topic or contrast feeling, while -이/가 here just straightforwardly marks who did the action.

제 means my in a polite or humble style. It is the shortened form of 저의.

• 저 = I / me, in a humble-polite form
• 저의 = my
• 제 = a very common shortened form of 저의

By contrast:

• 나 = I / me, casual
• 내 = my, casual

So 제 예약 is the polite way to say my reservation. This matches the polite ending -어요 in the sentence.

-을/를 is the object marker. It marks the thing being acted on.

• 예약 = reservation
• 예약을 = reservation + object marker

The thing being confirmed is the reservation, so 예약을 is the object of 확인하다.

다시 usually means again.

In this sentence, it suggests that the employee checked the reservation again, rechecked it, or double-checked it.

Depending on context, 다시 확인하다 can feel like:

• checking one more time
• checking it over again
• confirming it again after some issue or doubt

So 다시 adds the idea of repetition.

This part combines two ideas:

• 확인하다 = to check / confirm
• -아/어 주다 = to do something for someone

So:

• 확인해 주다 = to check/confirm something for someone
• 확인해 줬어요 = checked/confirmed it for someone

The 줬어요 part is the past polite form, so the whole phrase means something like checked it for me or confirmed it for me.

This is a very common question.

• 확인했어요 = checked/confirmed it
• 확인해 줬어요 = checked/confirmed it for me

The grammar -아/어 주다 adds a sense that the action was done as a favor, for someone’s benefit, or on someone’s behalf.

So the sentence is not just stating that the employee confirmed the reservation. It also suggests that the employee did this for the speaker, which is often a very natural thing to say in Korean.

It is understood, not directly stated.

In English, you often need to say for me, but in Korean that person is often omitted when it is obvious from context. In this sentence, the hidden beneficiary is the speaker, and that meaning comes from -아/어 주다.

So even though there is no separate word like 저에게 here, the sentence naturally implies:

• the employee rechecked my reservation
• the employee did that for me

If you wanted to make it explicit, you could say something like 직원이 저에게 제 예약을 다시 확인해 줬어요, but that would often sound unnecessary.

줬어요 is the contracted form of 주었어요.

Both mean the same thing:

• 주었어요 = full form
• 줬어요 = contracted, much more common in everyday speech

Korean often contracts vowel combinations in natural speech, and this is a standard example. So learners should recognize that 줬어요 is just the normal spoken/written conversational form.

It is polite informal speech, often called the -어요 style.

That means it is polite and natural in everyday conversation, but not the highest possible level of respect.

Because the subject is a staff member, some learners may expect an honorific form such as:

• 직원분이 제 예약을 다시 확인해 주셨어요

That version sounds more respectful toward the staff member because it uses:

• 직원분 instead of 직원
• 주셨어요 instead of 줬어요

Still, 직원이 제 예약을 다시 확인해 줬어요 is perfectly understandable and natural in many situations, especially in casual reporting.

Korean honorifics are optional depending on the situation, relationship, and tone.

Here, the speaker is simply reporting what happened in a polite sentence. That does not automatically require honorific marking for the employee.

But if the speaker wants to sound more respectful toward the staff member, Korean often changes both the noun and the verb:

• 직원 → 직원분
• 주다 → 주시다 in this grammar pattern, giving 해 주셨어요

So:

• neutral/polite report: 직원이 제 예약을 다시 확인해 줬어요
• more respectful: 직원분이 제 예약을 다시 확인해 주셨어요

Yes. Korean word order is more flexible than English, as long as the particles stay attached.

The most neutral order here is:

• 직원이 제 예약을 다시 확인해 줬어요

But you could also hear:

• 제 예약을 직원이 다시 확인해 줬어요
• 직원이 다시 제 예약을 확인해 줬어요

These all mean roughly the same thing, though the emphasis can shift slightly depending on what comes earlier in the sentence.

The particles are what keep the roles clear:

• 직원이 = subject
• 예약을 = object

It can be either, depending on context.

확인하다 often covers both:

• to check
• to confirm
• to verify

So 예약을 확인하다 could mean:

• check the reservation
• confirm the reservation
• verify the reservation details

In English, the best choice depends on the situation. If the staff member looked it up to make sure it was there, check may sound better. If they officially made sure it was valid or correct, confirm may sound better.

In theory, -아/어 주다 only means do something for someone, and that person can sometimes be understood from context rather than stated explicitly.

However, in this specific sentence, because it says 제 예약 (my reservation), the most natural interpretation is that the employee checked my reservation for me.

So in normal context, learners should understand the hidden beneficiary as the speaker.
