나와서 comes from 나오다 (to come out / to exit).

Breakdown:

• 나오- = verb stem
• -아/어서 = a connector meaning and, then, or after doing

Because 오 + 아서 contracts, 나오아서 becomes 나와서.

So 나와서 means something like:

• come out and...
• after coming out...

In this sentence, it links the two actions:

1. come out of the meeting room
2. rest briefly in the break room

Korean often connects related actions into one sentence with -아/어서.

Here, 회의실에서 나와서 휴게실에서 잠깐 쉬어요 sounds smooth and natural because the actions happen in sequence:

• first you leave the meeting room
• then you rest in the break room

Using -아/어서 makes the flow feel tighter than two separate sentences.

A very literal sense is:

• Coming out of the meeting room, [we] rest briefly in the break room.

In this sentence, -아서/-어서 is mainly showing sequence, not reason.

Because 에서 has more than one common job.

1) 회의실에서 나와서

Here, 에서 marks the starting point/source of movement:

• 회의실에서 나오다 = come out of the meeting room

So it works a bit like from or out of in English.

2) 휴게실에서 잠깐 쉬어요

Here, 에서 marks the place where an action happens:

• 휴게실에서 쉬다 = rest in the break room

So even though the same particle appears twice, it is doing two slightly different but related jobs.

Because 쉬다 is an action verb, and Korean usually uses 에서 for the place where an action happens.

• 휴게실에서 쉬어요 = correct/natural
• 휴게실에 쉬어요 = unnatural

A useful beginner rule:

• 에: destination or existence
  
  • 학교에 가요 = go to school
  • 집에 있어요 = be at home
• 에서: place where an action occurs
  
  • 학교에서 공부해요 = study at school
  • 휴게실에서 쉬어요 = rest in the break room

Korean often leaves out the subject when it is clear from context.

So 회의실에서 나와서 휴게실에서 잠깐 쉬어요 could mean:

• I come out of the meeting room and rest briefly in the break room.
• We come out of the meeting room and rest briefly in the break room.
• They do so.

English usually needs a subject, but Korean often does not.

This is very normal Korean. The listener is expected to understand the subject from the situation.

쉬어요 is the polite present-style form of 쉬다 (to rest).

Breakdown:

• 쉬다 = dictionary form
• 쉬어요 = polite everyday form

It is not formal-business style like 쉽니다, but it is polite and very common in conversation.

This form can sound like:

• a simple statement
• a description of what someone does
• sometimes a soft suggestion, depending on context and intonation

But by itself, it is basically a polite present-tense statement.

Because 쉬다 has the stem 쉬-, and when you add the polite ending -어요, you get:

• 쉬 + 어요 = 쉬어요

This is a regular conjugation.

So:

• 가다 → 가요
• 먹다 → 먹어요
• 쉬다 → 쉬어요

Nothing irregular is happening here.

잠깐 is an adverb meaning:

• for a moment
• briefly
• for a short while

It modifies 쉬어요, so it tells you how long the resting is.

So:

• 잠깐 쉬어요 = rest briefly / take a short break

It is commonly placed right before the verb, as in this sentence.

Yes, adverbs in Korean often have some flexibility.

These are all possible, with small differences in rhythm or emphasis:

• 휴게실에서 잠깐 쉬어요
• 잠깐 휴게실에서 쉬어요
• 회의실에서 나와서 잠깐 휴게실에서 쉬어요

The original version is very natural because 잠깐 sits right before the verb it modifies:

• 쉬어요

That makes it easy to understand.

Yes, you may hear 회의실을 나와서 too.

Both can be used with verbs like 나오다, but they feel a little different.

• 회의실에서 나오다 emphasizes the place you come out from
• 회의실을 나오다 is also used and can feel more like marking the place you exit as the object/path of movement

For a learner, 회의실에서 나와서 is very safe and natural.

So:

• 회의실에서 나와서 = excellent standard choice
• 회의실을 나와서 = also possible in many contexts

Both can connect verbs, but they are not exactly the same.

나와서

Often suggests:

• one action happens and then the next follows
• the two actions are closely connected

나오고

Simply links actions more neutrally:

• come out and...

In this sentence, 나와서 sounds more natural because leaving the meeting room leads directly into resting in the break room.

So:

• 회의실에서 나와서 휴게실에서 잠깐 쉬어요 = very natural
• 회의실에서 나오고 휴게실에서 잠깐 쉬어요 = possible, but a bit less smooth here

Not in this sentence.

The ending -아/어서 can sometimes mean because, but here the meaning is clearly sequence:

• come out of the meeting room
• then rest briefly in the break room

So here it means:

• and then
• after

not:

• because

Context usually makes this clear.

Korean present-style forms like 쉬어요 can cover several English ideas, depending on context.

This sentence could be understood as:

• a present/habitual action
• a plan happening soon
• a description of what people usually do in that situation

For example, in context it might mean:

• We come out of the meeting room and take a short break in the break room.
• Let’s step out of the meeting room and rest briefly in the break room.
  
  • This second, more suggestion-like feeling would depend on context and tone.

So the grammar itself is present polite, but the exact English translation can shift a bit.

The pattern is:

[place/source]에서 + [verb 1]-아서/어서 + [place of action]에서 + [adverb] + [verb 2]

In this sentence:

• 회의실에서 = from the meeting room
• 나와서 = come out and / after coming out
• 휴게실에서 = in the break room
• 잠깐 = briefly
• 쉬어요 = rest

This is a very common Korean way to describe actions in order.
