전에 means before.

In Korean, 전/전에 comes after the thing it refers to:

• 회의 전에 = before the meeting
• literally, it is closer to the meeting before

This is different from English, where before usually comes first.

A helpful pattern is:

• Noun + 전에 = before noun
• Verb stem + 기 전에 = before doing something

Examples:

• 점심 전에 = before lunch
• 자기 전에 = before sleeping

Both relate to before, and in many everyday sentences they are very similar.

• 회의 전 = before the meeting
• 회의 전에 = before the meeting

In this sentence, 전에 sounds very natural because it functions as a time expression for the action 정리해요.

A simple way to think about it:

• 전 often feels a bit more noun-like or compact
• 전에 is very common when saying before X, I do Y

So 회의 전에 책상을 정리해요 is a very standard, natural sentence.

을/를 is the object marker, and 책상 is the thing being organized.

• 책상 = desk
• 책상을 = desk + object marker

Since 정리하다 acts on something, that thing often takes 을/를:

• 책상을 정리해요 = tidy the desk
• 방을 정리해요 = tidy the room

You may hear 을/를 dropped in casual speech, but in a textbook-style sentence like this, keeping 책상을 is normal and clear.

Korean uses:

• 을 after a noun ending in a consonant
• 를 after a noun ending in a vowel

책상 ends in the consonant ㅇ, so it becomes:

• 책상 + 을 = 책상을

More examples:

• 문 → 문을
• 의자 → 의자를

깔끔하다 is an adjective meaning something like:

• neat
• tidy
• clean-looking

To change an adjective into an adverb in Korean, you often use -게:

• 깔끔하다 → 깔끔하게

So:

• 깔끔하게 정리해요 = organize/tidy up neatly

This is similar to how English adds -ly in many cases:

• neat → neatly

More examples:

• 조용하다 → 조용하게 = quietly
• 빠르다 → 빠르게 = quickly

This is a very common question, because both can relate to cleaning.

• 정리하다 = to organize, arrange, put in order, tidy up
• 청소하다 = to clean, sweep, wipe, remove dirt

So with a desk:

• 책상을 정리해요 = I tidy/organize the desk
  (arranging papers, putting things in order)
• 책상을 청소해요 = I clean the desk
  (wiping dust, cleaning the surface)

In this sentence, 정리해요 suggests making the desk neat and orderly, not necessarily scrubbing it.

The dictionary form is 정리하다.

When 하다 verbs are conjugated in the -아요/어요 polite style:

• 정리하다 → 정리해요

This happens because 하다 becomes 해요.

So:

• 공부하다 → 공부해요
• 청소하다 → 청소해요
• 정리하다 → 정리해요

You do not keep the full 하다 unchanged in this form.

Formally, 정리해요 is present tense, but Korean present tense is often broader than English present tense.

Depending on context, it can mean:

• I tidy the desk before the meeting (habitual)
• I’m tidying the desk before the meeting (present action, depending on context)
• I will tidy the desk before the meeting (near-future / planned action)

Because there is no separate future marker here, Korean relies on context.

So this sentence could describe:

• a routine
• a current situation
• a plan

The subject is omitted, which is very normal in Korean.

Korean often leaves out subjects when they are obvious from context. So this sentence could mean:

• I tidy the desk before the meeting.
• We tidy the desk before the meeting.
• He/She tidies the desk before the meeting.

In many real conversations, Korean speakers do not state the subject unless it is needed for clarity or emphasis.

If you wanted to add one, you could say:

• 저는 회의 전에 책상을 깔끔하게 정리해요. = I tidy the desk neatly before the meeting.

Yes. Korean word order is more flexible than English, especially with adverbs and time expressions.

The original sentence:

• 회의 전에 책상을 깔끔하게 정리해요.

Also possible:

• 회의 전에 깔끔하게 책상을 정리해요.
• 책상을 회의 전에 깔끔하게 정리해요.

These all mean basically the same thing, though the emphasis may shift slightly.

The most important thing is that:

• 회의 전에 stays together
• 책상을 stays marked as the object
• 정리해요 stays at the end

Korean verbs usually come at the end of the clause.

Yes, it is very natural.

정리하다 already means to put things in order, and 깔끔하게 adds the idea of doing it in a neat, tidy, clean-looking way.

So 깔끔하게 정리하다 means something like:

• tidy up neatly
• organize nicely
• put in order in a neat way

It is a very normal collocation in Korean.

Similar natural combinations:

• 방을 깔끔하게 정리하다 = tidy the room neatly
• 서류를 깔끔하게 정리하다 = organize the documents neatly

Yes, but -는 adds contrast or emphasis.

• 회의 전에 = before the meeting
• 회의 전에는 = as for before the meeting / at least before the meeting

So 회의 전에는 책상을 정리해요 can imply something like:

• Before the meeting, I do tidy the desk
• At least before the meeting, I tidy the desk
• maybe contrasting with another time when the desk is not tidy

Without special contrast, 회의 전에 is the more neutral choice.

책상 usually means desk, especially a desk for studying or working.

If you want to talk about a general table, 테이블 or 탁자 might be used depending on context.

So:

• 책상 = desk
• 탁자 = table
• 테이블 = table (loanword, common in many situations)

In this sentence, 책상 strongly suggests a work/study desk rather than just any table.
