watasi ha mainiti aoi suitou wo kaisya ni motte ikimasu.

は marks the topic of the sentence. Here, 私は means something like as for me. It does not just mark the subject mechanically; it sets up what the sentence is about.

You could use が in some contexts, but that would change the nuance. 私は sounds like a neutral statement about yourself, while 私が would more strongly emphasize I as the person doing it.

When は is used as a particle, it is pronounced wa. This is a standard feature of modern Japanese.

So 私は is read わたしは in writing, but pronounced watashi wa.

It can often be omitted. Japanese frequently leaves out subjects and topics when they are already clear from context.

So 毎日青い水筒を会社に持っていきます is a perfectly natural sentence if it is already obvious that you are talking about yourself.

毎日 is a time expression, and many common time expressions can be used without a particle. In this sentence, 毎日 works like every day and directly tells you when the action happens.

So:

• 毎日行きます = I go every day
• not usually 毎日に

By contrast, some specific time words often do take に, such as 7時に.

青い is an い-adjective, and い-adjectives directly modify nouns by going right in front of them.

So:

• 青い水筒 = a blue water bottle

This is similar to English word order, where blue comes before bottle.

水筒 is read すいとう (suitou). It usually means a water bottle, thermos, or flask, depending on context.

In this sentence, 青い水筒 is a blue water bottle.

を marks the direct object of the verb. It shows what thing is being carried or taken.

Here, 青い水筒を means that the blue water bottle is the thing being taken.

に marks the destination here. It tells you where the water bottle is being taken.

So 会社に持っていきます means take it to the company / to the office / to work.

Yes, へ is possible in many movement sentences because it also marks direction.

However, に is very common here because it marks the destination clearly and naturally. In this sentence, 会社に持っていきます is probably the most standard choice.

持っていきます is made from 持つ (to hold / to carry) and 行く (to go). Together, 持っていく means to take something along to another place.

So it is not just carry, and it is not just go. It specifically means take/carry something from here to there.

持ちます by itself usually means hold, carry, or have in a more general sense. It does not clearly include the idea of taking something to a destination.

持っていきます adds that destination idea, so it fits better for taking a water bottle to the office.

The difference is based on direction from the speaker’s point of view.

• 持っていきます = take it there
• 持ってきます = bring it here

If you are talking about taking the bottle from home to the office, 持っていきます makes sense. If you were bringing it to the place where the speaker is, 持ってきます would be used instead.

It is the polite non-past form. In Japanese, the non-past can refer to the present, the future, or a habitual action.

Because the sentence includes 毎日, it is understood as a habitual action: I take a blue water bottle to work every day.

Literally, 会社 means company. But in many everyday sentences, English speakers often translate it more naturally as the office or work.

So 会社に持っていきます may be translated naturally as:

• I take it to the office
• I bring it to work

Yes, Japanese word order is more flexible than English, as long as the particles stay attached to the right words. The verb also usually stays at the end.

For example, these are all possible:

• 私は毎日青い水筒を会社に持っていきます。
• 毎日、私は青い水筒を会社に持っていきます。
• 私は青い水筒を毎日会社に持っていきます。

They all mean roughly the same thing, though the emphasis may shift slightly.

No. Normal Japanese writing usually does not put spaces between words.

So this sentence would normally be written as: 私は毎日青い水筒を会社に持っていきます。

The spaces are only there to help learners see the parts more easily.
