업무 공간 literally means work space.

• 업무 = work, business duties, tasks
• 공간 = space

So this phrase can mean workspace, work area, or sometimes office space. It is a little broader than English office, because it focuses on the space used for work, not necessarily the whole company office.

이 is the subject marker.

Here, 공간 ends in a consonant, so the subject particle is 이.
If a noun ends in a vowel, you use 가 instead.

So:

• 공간이 = the workspace / workspace as the subject

In this sentence, 업무 공간이 is the thing being described as clean.

Yes, you can.

Both are natural, but the nuance changes a little:

• 업무 공간이 아주 깨끗해요: simply states that the workspace is very clean
• 업무 공간은 아주 깨끗해요: puts more focus on the workspace as the topic, often with a contrastive feel

For example, 은/는 can suggest something like:

• As for the workspace, it’s very clean
• maybe implying something else is not as clean

So 이/가 is more neutral here, while 은/는 can sound more topical or contrastive.

Yes. 아주 means very.

So 아주 깨끗해요 means is very clean.

A few similar words are:

• 아주 = very
• 매우 = very, highly, more formal/written
• 정말 = really
• 너무 = very / too, depending on context

In everyday speech, 아주 is common and natural.

Because 깨끗하다 is already the dictionary form meaning to be clean.

In Korean, many words that English speakers think of as adjectives behave like descriptive verbs. So instead of using a separate verb like to be, Korean often conjugates the descriptive word itself.

The dictionary form is:

• 깨끗하다 = to be clean

In the polite present style:

• 깨끗해요 = is clean / are clean

So the sentence ends naturally with 깨끗해요.

In Korean grammar, it is usually treated as a descriptive verb.

For English learners, it is often easiest to think of it as an adjective because it translates as clean. But grammatically, it behaves more like a verb in Korean because it conjugates and goes at the end of the sentence.

That is why Korean says:

• 공간이 깨끗해요

rather than putting clean directly before the noun the way English does in a clean space.

If you want to use it before a noun, it changes form:

• 깨끗한 공간 = a clean space

It follows the 하다 conjugation pattern.

• dictionary form: 깨끗하다
• polite present: 깨끗해요

This happens because 하다 commonly becomes 해요 in the polite present style.

So:

• 깨끗하다 → 깨끗해요

This is a very useful pattern to recognize, because many Korean words ending in 하다 conjugate the same way.

깨끗해요 is in the polite informal style, often called the 해요 style.

It is very common in everyday Korean and is appropriate in many normal situations.

Compare:

• 깨끗해 = casual, plain speech
• 깨끗해요 = polite everyday speech
• 깨끗합니다 = more formal

So this sentence sounds polite and natural for normal conversation.

Because Korean sentences often end with the main verb or descriptive verb.

English says:

• The workspace is very clean

Korean keeps the descriptive part at the end:

• 업무 공간이 아주 깨끗해요

A useful rough pattern is:

• noun + particle + adverb + descriptive verb

So Korean word order here is completely normal.

A natural pronunciation is close to:

엄무 공가니 아주 깨끄태요

A few sound changes happen:

• 업무 sounds like 엄무
• 공간이 sounds like 공가니
• 깨끗해요 sounds close to 깨끄태요

You do not need perfect sound-change knowledge right away, but it is helpful to know that spoken Korean often sounds a little different from the spelling.

Because Korean does not normally use articles like English a, an, and the.

So 업무 공간이 can mean:

• the workspace
• a workspace
• the work area

The exact meaning depends on context.

This is very normal in Korean, so you do not need to add anything to represent the or a.

Yes, if the context is already clear.

Korean often drops subjects when they are understood. So if everyone already knows you are talking about the workspace, you can simply say:

• 아주 깨끗해요 = It’s very clean

But if you want to clearly state what is clean, keeping 업무 공간이 is better.
