에 marks the place where something exists or is located.

In this sentence, 공용 공간에 means in the common/shared space.

Korean often uses:

• Noun + 에 있다 = to be at/in a place
• Noun + 에 없다 = to not be at/in a place

So:

• 공용 공간에 있어요 = It is in the common space / There is one in the common space

You would not usually use 에서 here, because 에서 is more often used for where an action happens, not where something simply exists.

Because 복사기 is not the object of an action here. It is the thing that exists.

• 가/이 marks the subject
• 를/을 marks the object

In 복사기가 있어요, the copier is the thing being identified as existing, so 가 is used.

Compare:

• 복사기가 있어요 = There is a copier
• 복사기를 써요 = I use the copier

In the second sentence, 복사기 is the object of use, so it takes 를.

가 is often used when introducing or pointing out the existence of something.

So 복사기가 있어요 sounds natural for:

• There is a copier
• A copier exists

If you say 복사기는 있어요, it changes the nuance. It can sound like:

• As for the copier, there is one
• There is a copier, at least
• contrastive emphasis, depending on context

So in a simple neutral statement of existence, 가 is the most natural choice.

있어요 is the polite present form of 있다.

It can mean:

• to exist
• to be present
• to be located
• sometimes to have, depending on the sentence

In this sentence, it means there is or is located.

So:

• 복사기가 있어요 = There is a copier
• 공용 공간에 복사기가 있어요 = There is a copier in the common space

This is not the progressive is being. It is a basic existence/location verb.

Korean often puts background information first, especially time and place.

So the structure here is:

• 공용 공간에 = location
• 복사기가 = thing that exists
• 있어요 = exists / is there

This order is very natural in Korean.

A useful pattern is:

[Place]에 [Thing]이/가 있어요
= There is [thing] in [place]

So this sentence follows a very common Korean word order.

공용 means shared, common-use, or for public/common use.
공간 means space.

So 공용 공간 means something like:

• common space
• shared space
• communal area

The exact English translation depends on context, but the Korean phrase itself is straightforward: a space used in common by multiple people.

복사기 most directly means copier or copy machine.

It usually refers to a machine for making copies. In real-life usage, people may sometimes be talking about a large office machine that also prints and scans, but the word itself focuses on the copying function.

Some related words:

• 복사기 = copier
• 프린터 = printer
• 복합기 = multifunction printer/copier/scanner

So if you want to be exact, 복사기 is copier.

Normally, no. 에 is the natural choice here, not 에서.

Why?

• 에 = location of existence
• 에서 = location where an action takes place

Since 있어요 expresses existence, Korean uses 에.

Compare:

• 공용 공간에 복사기가 있어요 = There is a copier in the common space
• 공용 공간에서 복사해요 = I make copies in the common space

The second sentence uses 에서 because 복사해요 is an action.

Yes, if the context is clear.

For example:

• 복사기가 있어요. = There is a copier.
• 공용 공간에 있어요. = It is in the common space.

Korean often omits information that both speakers already understand.

So if someone asks:

• 복사기 어디 있어요? = Where is the copier?

You could answer:

• 공용 공간에 있어요.

And if someone asks:

• 공용 공간에 뭐가 있어요? = What is in the common space?

You could answer:

• 복사기가 있어요.

Yes. 있어요 is the standard polite style used in everyday conversation.

Levels you might see:

• 있어 = casual
• 있어요 = polite, everyday
• 있습니다 = formal

So:

• 공용 공간에 복사기가 있어요. = natural polite speech
• 공용 공간에 복사기가 있습니다. = more formal, such as in announcements, signage, or business contexts

Both are correct; they just differ in formality.

A natural pronunciation is close to:

• 복사기가 → 복싸기가
• 있어요 → 이써요

So the full sentence sounds roughly like:

공용 공간에 복싸기가 이써요

This happens because Korean pronunciation changes can make certain consonants sound stronger in connected speech.

You do not need to change the spelling, though. The written form stays:

공용 공간에 복사기가 있어요.
