일단 means first, for now, or to start with, depending on context.

In this sentence, it suggests the first step in a sequence:

• 일단 행사장에서 준비물을 확인해요.
  = First, let’s check the supplies at the event venue.

It often gives the feeling of before doing anything else, do this first.

The particle -에서 is used for the place where an action happens.

Here, 확인해요 (check/confirm) is an action, so Korean uses 행사장에서:

• 행사장 = event venue
• 행사장에서 = at the event venue

Compare:

• 행사장에 가요 = go to the event venue
• 행사장에서 확인해요 = check something at the event venue

So:

• -에 often marks a destination or location of existence
• -에서 marks the place where an action is performed

준비물 means things that need to be prepared, supplies, or materials to bring.

It is made of:

• 준비 = preparation
• 물 = thing/item/object

So 준비물 refers to the items needed for an event, class, trip, etc.

Examples:

• 소풍 준비물 = picnic supplies / things to bring for a picnic
• 수업 준비물 = class materials

In this sentence, it probably means the necessary items for the event.

-을 / -를 is the object particle. It marks what is being acted on.

Here, the thing being checked is 준비물, so:

• 준비물을 확인해요 = check the supplies

Since 준비물 ends in a consonant, it takes -을.

Quick rule:

• consonant + 을
• vowel + 를

Examples:

• 책을 읽어요 = read a book
• 커피를 마셔요 = drink coffee

Yes, 확인하다 usually means to check, to confirm, or to verify.

It often sounds a little more like make sure or confirm carefully than a casual look at.

So 준비물을 확인해요 can mean:

• check the supplies
• confirm the supplies
• make sure the supplies are there

It is commonly used in practical situations:

• 예약을 확인해요 = confirm the reservation
• 시간을 확인해요 = check the time
• 명단을 확인해요 = check the list

Yes, 확인해요 is the present polite form of 확인하다.

Breakdown:

• dictionary form: 확인하다
• polite present: 확인해요

In Korean, this form can mean:

• a present action: check
• a habitual action: check regularly
• an instruction/suggestion in context: let’s check / we check

So depending on situation, 확인해요 could sound like:

• I check
• we check
• please check
• let’s check

Korean often leaves the subject and exact force to context.

Korean often omits the subject when it is obvious from context.

So 일단 행사장에서 준비물을 확인해요 does not explicitly say:

• I
• we
• you

Possible natural interpretations are:

• First, we check the supplies at the venue.
• First, let’s check the supplies at the venue.
• First, check the supplies at the venue.

The intended meaning depends on the situation:

• instructions to staff
• a plan being discussed
• a narration of steps

This is very normal in Korean.

Yes. Korean word order is usually Subject–Object–Verb, and place expressions often come before the object or verb.

This sentence is structured like:

• 일단 = first
• 행사장에서 = at the event venue
• 준비물을 = the supplies
• 확인해요 = check

So literally, it is closer to:

• First, at the event venue, the supplies check.

Natural English rearranges this as:

• First, check the supplies at the event venue.

The verb normally comes at the end in Korean.

That would sound unnatural.

Because 확인하다 is an action happening in a place, Korean normally uses -에서 for the location:

• 행사장에서 준비물을 확인해요 = correct

Using -에 here would not be the normal way to mark the place of checking.

So for this sentence, -에서 is the right particle.

-해요 style is polite and very common in everyday speech, meetings, and casual workplace communication.

So 일단 행사장에서 준비물을 확인해요 is polite and natural in many situations.

However, in more formal business writing or official announcements, you might see -합니다 style instead:

• 일단 행사장에서 준비물을 확인합니다.

Comparison:

• 확인해요 = polite, conversational
• 확인합니다 = more formal, professional, official

Yes. In context, it very easily can.

The -해요 ending does not always map neatly to one English form. Korean often relies on tone and situation.

For example, during planning, this could mean:

• First, let’s check the supplies at the venue.

During an explanation of procedure, it could mean:

• First, we check the supplies at the venue.

When gently telling someone what to do, it might even function like:

• First, check the supplies at the venue.

So the Korean form is flexible, and English translation changes depending on context.
