전에 means before.

So 수업 전에 literally means before class or before the lesson.

• 수업 = class / lesson
• 전 = before
• -에 makes it function naturally in a time expression

In Korean, N 전에 is a very common pattern meaning before N:

• 식사 전에 = before the meal
• 자기 전에 = before sleeping
• 시험 전에 = before the test

So here, 수업 전에 tells you when to do the action.

이랑 means and / with in casual spoken Korean.

So:

• 필통이랑 풀을 = the pencil case and the glue

A learner should notice that 이랑 is more conversational than 와/과. You could also say:

• 필통과 풀을 = more formal/written
• 필통하고 풀을 = also common in speech
• 필통이랑 풀을 = casual and natural in everyday speech

Even though 이랑 can also mean with, in this sentence it clearly means and, because it is linking two objects.

Because the whole phrase 필통이랑 풀 is treated as one combined object phrase: the pencil case and the glue.

Korean often puts the case particle only on the last item in a list like this:

• 필통이랑 풀을
• literally: pencil case-and glue-OBJ

That final 을 applies to the whole coordinated phrase.

You could think of it as:

• [필통이랑 풀]을

This is very natural in Korean. English learners often expect every noun to get its own marker, but Korean usually does not do that in this kind of structure.

Yes. In this sentence, 풀 means glue.

This can confuse learners because 풀 can also mean grass in other contexts. Korean has many words that sound the same but mean different things depending on context.

Here, because the sentence is about school supplies and taking things out onto a desk, 풀 clearly means glue.

So:

• 필통 = pencil case
• 풀 = glue

책상 위에 means on the desk.

Breakdown:

• 책상 = desk
• 위 = top / upper side
• 위에 = on top of / on

So 책상 위에 literally means on top of the desk.

The particle 에 is used because it marks the location where something is placed or exists.

Compare:

• 책상 위 = the top of the desk / desk surface
• 책상 위에 = on the desk

Since the sentence says to put the items somewhere, 에 is the natural location particle.

This is a very important nuance.

• 꺼내세요 = take it out
• 꺼내 놓으세요 = take it out and leave it out / set it out in advance

The grammar -아/어 놓다 adds the idea of doing something and leaving it in that state, often for later use or preparation.

So in this sentence, 꺼내 놓으세요 suggests:

• take out the pencil case and glue
• place them on the desk
• leave them there ready for class

That fits the context of classroom preparation much better than just 꺼내세요.

-아/어 놓다 means something like:

• do something and leave it that way
• do something in advance
• put something in a prepared state

In this sentence:

• 꺼내다 = to take out
• 꺼내 놓다 = to take out and leave out / set out

Some other examples:

• 문을 열어 놓았어요. = I opened the door and left it open.
• 숙제를 해 놓았어요. = I did the homework in advance.
• 물 좀 받아 놓으세요. = Please fill some water in advance / and keep it ready.

So here the teacher is not just telling students to remove the items from the pencil case or bag, but to have them ready on the desk.

-세요 is a polite ending used for requests, instructions, and polite commands.

So 꺼내 놓으세요 is basically:

• Please take them out and place them on the desk.

It is polite, but it still has the force of an instruction. In a classroom, this is very natural for a teacher speaking to students.

Compared with other endings:

• 꺼내 놓아라 = plain command, stronger / less polite
• 꺼내 놓으세요 = polite instruction/request
• 꺼내 놓아 주세요 = please do it for me, often a bit softer depending on context

So yes, it functions like a command, but in a polite form.

Because Korean normally puts location phrases before the verb.

Korean word order is flexible, but the default pattern is that most information comes before the final verb. So this sentence is organized roughly like this:

• 수업 전에 = when
• 필통이랑 풀을 = what
• 책상 위에 = where
• 꺼내 놓으세요 = what to do

That final verb tells you the action at the end, which is very normal in Korean.

English speakers often want to translate word-for-word in English order, but Korean usually builds the sentence by stacking time, object, and location before the verb.

Not naturally. The sentence means to take out both the pencil case and the glue.

That is because 필통이랑 풀을 links two separate objects:

• 필통 = pencil case
• 풀 = glue

If Korean wanted to say take the glue out of the pencil case, it would need a different structure, such as one marking 필통에서 or something similar:

• 필통에서 풀을 꺼내세요. = Take the glue out of the pencil case.

So the original sentence definitely means to place the pencil case and the glue on the desk.

Yes, 이랑 is somewhat casual and spoken-sounding.

In everyday speech, especially in classrooms, it is very natural. A teacher saying this aloud to students sounds fine.

But in a more formal written instruction, you might see:

• 필통과 풀을 책상 위에 꺼내 놓으세요.

That version feels a bit more formal because 과 is more formal than 이랑.

So:

• 이랑 = casual, natural in speech
• 하고 = also common and conversational
• 와/과 = more formal or neutral in writing

Sometimes yes, but here it works more as part of the expression 꺼내 놓으세요.

By itself:

• 놓다 = to put, place, set down

But in 꺼내 놓다, it has a grammatical function too: it adds the idea of leave it out / keep it prepared.

So while there is still a sense of physically placing something somewhere, the bigger meaning is:

• take it out and leave it there ready

That is why translating it simply as put would miss part of the meaning.

The tone is polite, practical, and instructional.

It sounds like something a teacher would say before class starts:

• Before class, please take out your pencil case and glue and place them on top of your desk.

It is not especially warm or soft, but it is not rude either. It is a normal classroom direction.

The sentence feels efficient because Korean classroom instructions often focus on:

• time first
• needed items
• location
• action

So the tone is very natural for organizing students and getting them ready.
