watasi ha asita no kaigi ni siryou wo motte ikimasu.

No. Normal Japanese writing does not use spaces between words.

This sentence would usually be written as:

私は明日の会議に資料を持っていきます。

Spaces are often added in beginner materials to make the parts easier to see.

Yes, it can often be omitted.

Japanese frequently leaves out subjects when they are clear from context. So in a real conversation, a speaker might simply say:

明日の会議に資料を持っていきます。

Including 私 makes the subject explicit: as for me / I. Textbooks often include it more than native speakers do.

は marks the topic of the sentence, while が more strongly marks the subject or gives new/emphatic information.

So:

• 私は... = As for me, ...
• 私が... = I am the one who ... or a more focused I

In this sentence, 私は sounds natural because the speaker is just stating what they will do, not emphasizing that it is specifically I and not someone else.

Here, の connects 明日 and 会議 so that 明日 modifies 会議.

So:

• 明日 = tomorrow
• 会議 = meeting
• 明日の会議 = tomorrow’s meeting / the meeting tomorrow

This is a very common pattern in Japanese: noun + の + noun.

Examples:

• 日本の会社 = a Japanese company / a company in Japan
• 学校の先生 = a school teacher / the school’s teacher

In this sentence, に marks the destination or target of the action.

The verb 持っていく means to take something somewhere, so 会議に means to the meeting.

It is not just saying the meeting exists; it is showing where the materials are being taken.

を marks the direct object of the verb, meaning the thing being acted on.

Here:

• 資料 = materials / documents
• 資料を = the materials (as the thing being taken)

So 資料を持っていきます means will take the materials.

資料 usually means materials, documents, or reference materials, depending on context.

Japanese nouns usually do not show singular vs. plural the way English nouns do. So 資料 could mean:

• a document
• documents
• materials

The context tells you which meaning is most natural. In a meeting context, materials or documents is often the best translation.

Because 持っていく means to take/carry something to another place, while 持つ just means to hold or to have.

Compare:

• 資料を持ちます = I hold/have the materials
• 資料を持っていきます = I take the materials there

So the て-form + いく adds the idea of going somewhere with it.

It is made from:

• 持つ = to hold / carry
• 持って = the て-form of 持つ
• いく = to go
• いきます = polite form of いく

Together, 持っていく literally has the sense of carry and go, which becomes the natural English idea take (something) somewhere.

This is a very common Japanese pattern:

• verb in て-form + いく
• often gives a sense of doing something and going away / doing something toward a destination

The difference is about direction and point of view.

• 持っていく = take something from here to there
• 持ってくる = bring something from there to here (or toward the speaker’s point of view)

In this sentence, the meeting is treated as the place the speaker is going to, so 持っていきます is natural.

If someone at the meeting asked you to bring the materials, from their point of view they might say:

明日の会議に資料を持ってきてください。
= Please bring the materials to tomorrow’s meeting.

So both can be possible in different contexts, but the viewpoint changes.

Japanese non-past forms often cover both present and future.

So 持っていきます can mean:

• I take (habitual, depending on context)
• I will take (future)

In this sentence, because of 明日 (tomorrow), it is clearly future: I will take the materials to tomorrow’s meeting.

Yes, Japanese word order is more flexible than English, because particles show the role of each part.

The most basic order is often:

Topic + time + destination + object + verb

So this sentence is very natural: 私は明日の会議に資料を持っていきます。

But other orders can also work, for example:

私は資料を明日の会議に持っていきます。

This still means basically the same thing, because:

• に marks the destination
• を marks the object

The verb usually stays at the end.

Yes. Time expressions are often quite flexible in Japanese.

For example, you could also say:

私は資料を明日の会議に持っていきます。

or even:

明日の会議に私は資料を持っていきます。

The nuance may shift slightly depending on what you want to emphasize, but the basic meaning stays the same. Japanese relies heavily on particles, so moving parts around is often possible as long as the sentence remains clear.
