책상 위에 means on the desk or more literally on top of the desk.

• 책상 = desk
• 위 = top, above
• -에 = a location particle

So 책상 위에 휴지가 없어서 means because there were no tissues on the desk.

In Korean, 위에 is very commonly used to say that something exists or is located on top of something.

Here, -에 is used because the sentence is talking about where something exists.

• 휴지가 없다 = there is no tissue
• When talking about existence with 있다/없다, Korean normally uses -에 for the location.

So:

• 책상 위에 휴지가 없다 = There is no tissue on the desk.

If you used -에서, it would sound more like the desk is the place where an action happens, which is not the point in this part of the sentence.

With 있다 and 없다, the thing that exists or does not exist often takes -이/가.

So:

• 휴지가 없다 = tissues are not there / there is no tissue

Here, 휴지 is the thing whose existence is being talked about, so -가 is natural.

English learners sometimes expect something like 휴지를 없다, but that is not how 없다 works. 없다 does not take a direct object the way a verb like 먹다 does.

휴지 can mean several related things depending on context:

• tissue
• toilet paper
• paper napkin
• scrap paper in some situations

In this sentence, it most likely means tissue or paper towel-like paper—something you could use to pick up a small piece of trash. So in natural English, tissue is probably the best fit.

Here, -어서 means because.

• 없다 = to not exist, to not be there
• 없어서 = because there wasn’t / because there were not

So:

• 책상 위에 휴지가 없어서 = because there were no tissues on the desk

This form connects the reason to the result in the next clause.

It can also simply connect actions in some sentences, but here it clearly gives a reason.

Literally, 작은 쓰레기 is small trash:

• 작은 = small
• 쓰레기 = trash, garbage

But in natural English, this often means a small piece of trash or some small trash.

Korean nouns do not always mark singular vs. plural clearly, so 쓰레기 could refer to:

• one small piece of trash
• small bits of trash
• a small amount of trash

The exact interpretation depends on context.

Because 쓰레기 is the direct object of 치우다.

• 치우다 = to clean up, put away, remove
• 쓰레기를 치우다 = to clean up/remove the trash

So:

• 작은 쓰레기를 = the small piece of trash / the small trash

The particle -을/를 marks what is being cleaned up.

바로 here means right away, immediately, or on the spot.

So:

• 작은 쓰레기를 바로 못 치웠어 = I couldn’t clean up the small piece of trash right away

It gives the sense that the speaker wanted to deal with it immediately, but couldn’t.

This is an important difference.

• 안 치웠어 = I didn’t clean it up
• 못 치웠어 = I couldn’t clean it up

못 expresses inability or impossibility, not just choice.

In this sentence, the reason is given:

• 휴지가 없어서 = because there were no tissues

So the speaker is saying they were unable to clean it up right away, not simply that they chose not to.

치우다 means things like:

• to put away
• to clear away
• to clean up
• to remove

In this sentence, 치웠어 means cleaned it up or cleared it away.

청소하다 usually means to clean in a broader sense, like cleaning a room, house, or area in general.

Compare:

• 쓰레기를 치우다 = remove/clean up the trash
• 방을 청소하다 = clean the room

So 치우다 is more natural here because the speaker is dealing with a specific piece of trash.

못 치웠어 is:

• past tense
• casual/informal speech

Breakdown:

• 치우다 = to clean up
• 치웠어 = cleaned up
• 못 치웠어 = couldn’t clean up

This ending is used with:

• friends
• family
• people you are close to
• casual conversation

A more polite version would be:

• 책상 위에 휴지가 없어서 작은 쓰레기를 바로 못 치웠어요.

Yes, that is the natural implication.

The sentence suggests:

• there was a small piece of trash
• the speaker wanted to clean it up right away
• but there were no tissues on the desk
• so they couldn’t do it immediately

It sounds like the speaker wanted to pick it up using a tissue rather than with their bare hand.

Yes. Depending on context, natural translations include:

• There weren’t any tissues on the desk, so I couldn’t clean up the small piece of trash right away.
• Because there were no tissues on the desk, I couldn’t immediately pick up the little bit of trash.
• I couldn’t clean up the small trash right away because there were no tissues on the desk.

The Korean is flexible enough that several English versions can work. The main ideas are:

1. no tissues were available on the desk
2. because of that, the speaker could not clean up the trash immediately
