modu hyeopryeokhaeseo gibu mulpumeul jeonghwakhage bunryuhaeyo.

It can mean either, depending on context.

In this sentence, 모두 most naturally means everyone or all together. It gives the idea that the people involved are acting as a group.

So it suggests something like:

• everyone
• all of us
• together

Korean often leaves the subject unstated, so 모두 helps show that this is a group action.

협력해서 comes from 협력하다 (to cooperate / collaborate) plus -아서/어서, which becomes 해서 after 하다 verbs.

So:

• 협력하다 = to cooperate
• 협력해서 = cooperating and..., by cooperating, or working together and...

In this sentence, -해서 links 협력하다 to the next action, 분류해요.

It can sound like:

• cooperate and sort
• work together to sort
• sort by cooperating

So -해서 is a very common connector used to join actions.

Good question. In Korean, 협력하다 often appears with a partner marked by -와/과, -하고, or -랑, such as:

• 친구와 협력하다 = to cooperate with a friend

But it can also be used without stating the partner if that is obvious from context.

Here, 모두 already gives the idea that everyone is working together, so Korean does not need to explicitly say with each other.

So the sentence feels natural even without something like:

• 모두 서로 협력해서...

That version is possible too, but the original is more concise.

기부 물품 is a noun phrase meaning donated items, donation goods, or items for donation, depending on context.

Breakdown:

• 기부 = donation
• 물품 = goods, items, supplies

So 기부 물품 refers to physical items connected with donation, such as clothes, books, food, or household goods.

A learner should also know that 물품 sounds a bit more formal or organizational than everyday 물건.

• 물건 = thing, object, item
• 물품 = goods/items/supplies, often in official or workplace contexts

Because 기부 물품 is the object of 분류해요.

• 분류하다 = to classify / sort
• What are we sorting? 기부 물품

So the object marker 을 is attached to the final noun in the noun phrase:

• 기부 물품을

This is very normal in Korean. The whole phrase acts as one object, and the particle goes at the end.

Yes, both are possible.

• 정확하게
• 정확히

Both mean accurately.

Here, 정확하게 분류해요 sounds completely natural.
정확히 분류해요 would also be natural.

Very roughly:

• 정확하게 can feel a little more like in an accurate way
• 정확히 is a little more compact and very commonly used

In many real situations, the difference is small, and both are acceptable.

분류해요 comes from 분류하다, which means to classify, to sort into categories, or to separate by type.

So it is specifically about putting things into categories.

By contrast:

• 정리하다 = to organize, tidy up, arrange
• 분류하다 = to classify, sort by category

For example:

• 책상을 정리해요 = organize the desk
• 옷을 분류해요 = sort the clothes by type

In this sentence, 분류해요 is a good choice because donated items are usually being sorted into categories such as clothes, books, toys, and so on.

해요 is the polite informal style, often called the -요 style.

Here is the difference:

• 해요 = polite, common in everyday speech
• 합니다 = more formal, often used in announcements, presentations, or official settings
• 하세요 = polite command, meaning please do

So the sentence with 해요 sounds polite and friendly. It can fit a group activity, volunteer setting, classroom, or instructional context.

If you changed it:

• 모두 협력해서 기부 물품을 정확하게 분류합니다.
  More formal, report-like or official.

• 모두 협력해서 기부 물품을 정확하게 분류하세요.
  Clearer as a direct instruction: Please sort the donated items accurately while cooperating.

Formally, 해요 is a statement form, so on the surface it means something like (we/they) sort.

But in real Korean, this form is often used in instructions, group guidance, and encouraging statements. So depending on context, it may feel like:

• a statement: We sort the donated items accurately by cooperating
• a gentle instruction: Please work together and sort the donated items accurately
• a group-oriented encouragement: Let’s all work together and sort the donated items accurately

Korean often relies on context more than English does, so one form can cover several natural English translations.

The order is fairly flexible, because Korean uses particles to show grammatical roles.

Original:

• 모두 협력해서 기부 물품을 정확하게 분류해요.

You could also move some parts around, for example:

• 기부 물품을 모두 협력해서 정확하게 분류해요.
• 모두 기부 물품을 협력해서 정확하게 분류해요.

These are understandable, but the original sounds smooth and natural.

A useful thing to remember is:

• 기부 물품을 stays together because it is the object
• 정확하게 usually stays near the verb it modifies
• 협력해서 usually comes before the main action it supports

So the original order is a very natural default.

Yes, but the nuance changes.

• 같이 = together
• 함께 = together, somewhat neater or slightly more formal than 같이
• 협력해서 = by cooperating / through cooperation

So:

• 모두 같이 기부 물품을 정확하게 분류해요.
  Everyone sorts the donated items together.

• 모두 함께 기부 물품을 정확하게 분류해요.
  Very similar, a bit smoother or more polished.

• 모두 협력해서 기부 물품을 정확하게 분류해요.
  Emphasizes cooperation and working collaboratively.

So 협력해서 adds a stronger sense of teamwork, not just physical togetherness.
