kosi wo hakobimasu.

It is read:

こし を はこびます
koshi o hakobimasu

A few pronunciation notes:

• 古紙 = こし (koshi)
• を is the object particle. In modern Japanese, it is usually pronounced お.
• 運びます = はこびます (hakobimasu)

So the full sentence sounds like koshi o hakobimasu.

古紙 means waste paper, used paper, or recyclable paper.

It does not just mean any paper in general. It specifically refers to paper that has already been used and is being collected, recycled, or disposed of.

For example, it can refer to things like:

• old newspapers
• used cardboard
• old magazines
• recyclable paper scraps

So 古紙 is a more specific word than just 紙 (かみ, paper).

を marks the direct object of the verb.

In this sentence:

• 古紙 = the thing being carried
• 運びます = carry / transport
• を connects them and shows that 古紙 is what is being transported

So structurally, the sentence is:

古紙 を 運びます
[waste paper] + [object marker] + [carry/transport]

This is very common in Japanese:

• 荷物を運びます = carry luggage
• 本を読みます = read a book
• 水を飲みます = drink water

Japanese often leaves out the subject when it is understood from context.

So 古紙を運びます could mean:

• I carry waste paper
• We carry waste paper
• He/She carries waste paper
• They carry waste paper
• (Someone) will carry waste paper

The exact subject depends on the situation.

This is normal Japanese. If the subject is obvious, it is usually omitted.

運びます is the polite non-past form.

In Japanese, the non-past can mean:

• present / habitual: (I/they) carry waste paper
• future: (I/they) will carry waste paper

Japanese does not force the same clear present-vs-future distinction that English often does. Context tells you which meaning is intended.

So 古紙を運びます can mean either:

• carry waste paper
• will carry waste paper

depending on the situation.

The dictionary form is 運ぶ (はこぶ, hakobu).

This is the plain form of the verb.

• 運ぶ = plain / dictionary form
• 運びます = polite form

This verb means to carry, to transport, or to move something from one place to another.

Because 運ぶ is a godan verb.

For godan verbs ending in -ぶ, the polite -ます form changes ぶ to び:

• 運ぶ → 運びます
• 遊ぶ → 遊びます
• 呼ぶ → 呼びます

So:

1. Start with 運ぶ
2. Change ぶ to び
3. Add ます

Result: 運びます

Both can involve carrying, but they are not exactly the same.

持つ often means:

• to hold
• to have
• to carry on your person

Example:

• かばんを持ちます = carry/hold a bag

運ぶ often means:

• to transport
• to carry something from one place to another
• to move something as cargo, goods, or materials

Example:

• 荷物を運びます = transport luggage
• 古紙を運びます = transport waste paper

So in this sentence, 運びます suggests actual movement/transport, not just holding something.

Japanese nouns usually do not change form for singular and plural.

So 古紙 can mean:

• waste paper
• some waste paper
• waste papers
• recyclable paper materials

The exact number is not stated unless context makes it clear.

That means 古紙を運びます could refer to one bundle of waste paper or a larger amount.

The spaces are probably there just for learners.

Normal Japanese is usually written without spaces, so this sentence would normally appear as:

古紙を運びます。

Textbooks and beginner materials sometimes insert spaces to make the grammar easier to see:

• 古紙
• を
• 運びます

But in standard writing, you usually will not see those spaces.

It is written を, and in romanization it is often shown as o or sometimes wo.

In modern standard Japanese, it is usually pronounced simply as:

お

So:

• written: を
• usually pronounced: お

That is why 古紙を運びます sounds like:

こし お はこびます

even though the particle is written を.

Yes. 運びます is polite because it uses the -ます form.

So the sentence is appropriate in many neutral or polite situations, such as:

• workplace communication
• instructions
• formal descriptions
• textbook example sentences

The plain version would be:

古紙を運ぶ。

That sounds less polite and more casual/plain.

Yes, very naturally.

Because the subject is omitted and the verb is in a neutral polite form, 古紙を運びます can sound like:

• a statement of what someone does
• a work duty
• a step in a process
• an instruction in context

For example, in a recycling or warehouse setting, it could mean something like:

• We transport waste paper.
• The worker carries the waste paper.
• You will carry the waste paper.

Japanese often relies on context for exactly who is doing the action.
