Here, 会議に必要な書類 means documents necessary for the meeting.

The particle に marks what something is related to in the pattern:

A に 必要(な) B
= B that is necessary for A

So:

• 会議に必要な書類 = documents needed for the meeting

In English, this often becomes for, but in Japanese the particle is に.

必要 is a na-adjective.

Na-adjectives use な when they directly modify a noun:

• 必要な書類 = necessary documents
• 静かな部屋 = a quiet room
• 有名な人 = a famous person

So 必要な書類 is correct because 必要 is describing 書類.

It is not 必要い because 必要 is not an i-adjective.

This is a noun phrase built from a modifier plus a noun:

• 会議に = for the meeting
• 必要な = necessary
• 書類 = documents

Together:

• 会議に必要な書類 = the documents necessary for the meeting

A helpful way to think about it is that Japanese puts descriptive information before the noun. So the whole chunk 会議に必要な modifies 書類.

を marks the direct object of the verb.

The action here is 持って来てください = please bring.
What should be brought? 書類.

So:

• 書類を持って来てください = please bring the documents

Even though English may say bring the documents, Japanese shows the object clearly with を.

明日 is a time expression meaning tomorrow.

Time words in Japanese are often placed before the main verb:

• 明日行きます = I will go tomorrow
• 明日持って来てください = Please bring it tomorrow

Japanese word order is fairly flexible, but time expressions commonly appear before the verb phrase. So this sentence sounds very natural.

This is a very common pattern.

• 持つ = to hold / to carry
• 来る = to come

When combined as 持って来る, it means to bring, literally to carry and come.

So:

• 持って来てください = please bring it

This is different from just:

• 持ってください = please hold it / please carry it
• 来てください = please come

Neither of those alone means bring. Japanese often expresses bring as 持って来る.

Japanese chooses 来る or 行く based on the direction relative to the speaker or destination being treated as the speaker’s side.

• 来る = come, toward here / toward the relevant place
• 行く = go, away from here

If someone is telling you to bring documents to the meeting or to the speaker’s location, 持って来てください is natural: please bring them here / to us.

If the context were different, 持って行ってください could mean please take them there.

So the choice depends on perspective.

Yes. Japanese very often leaves out the subject when it is obvious from context.

This sentence does not explicitly say:

• who should bring the documents
• who is asking
• whose meeting it is

But from context, it is understood as something like:

• (You) please bring the documents needed for the meeting tomorrow.

This omission is normal and natural in Japanese.

Yes. 〜てください is a standard polite way to ask someone to do something.

• 持って来てください = please bring it

It is polite and common in everyday speech, work situations, and instructions.

Depending on context, it can sound:

• neutral-polite
• direct but still respectful

More formal alternatives exist, such as:

• 持って来てくださいませんか
• お持ちください
• お持ちいただけますか

But 〜てください is very common and appropriate in many situations.

Yes. 持って来てください and 持ってきてください mean the same thing.

The difference is mainly in writing style:

• 持って来てください uses the kanji 来
• 持ってきてください writes きて in hiragana

Both are natural. In everyday writing, Japanese often uses hiragana for auxiliary parts like くる / きて, so 持ってきてください is very common.

They are:

• 会議 → かいぎ
• に → に
• 必要な → ひつような
• 書類 → しょるい
• を → を (pronounced お in modern Japanese speech)
• 明日 → あした
• 持って → もって
• 来て → きて
• ください → ください

So the full sentence is read:

かいぎ に ひつような しょるい を あした もって きて ください

To some extent, yes. Japanese word order is more flexible than English, as long as the particles make the roles clear.

For example, these are all understandable:

• 会議に必要な書類を明日持って来てください
• 明日、会議に必要な書類を持って来てください

Both are natural.

However, the most important rule is that the verb phrase usually comes at the end, and modifiers should stay close to what they modify. So 会議に必要な should stay attached to 書類.
