syuumatu ni kodomo wo doubutuen ni turete ikimasu

They are doing two different jobs:

• 週末に: に marks the time: on the weekend / at the weekend
• 動物園に: に marks the destination: to the zoo

So even though the particle is the same, the meaning depends on what it is attached to.

In this sentence, 子供を連れて行きます means take the child/children along.

Here, を marks the person being taken. So the child is the object of 連れて行きます.

Compare:

• 子供を動物園に連れて行きます = I will take the child to the zoo.
• 子供と動物園に行きます = I will go to the zoo with the child.

Those are similar in English, but in Japanese they are structured differently.

連れて行きます is a very common pattern meaning to take someone (along) somewhere.

It comes from:

• 連れる = to take someone along
• 行く = to go

The て-form of 連れる is 連れて, so:

• 連れる → 連れて
• 連れて行く = to go taking someone along
• 連れて行きます = polite non-past form

So this whole expression acts almost like one verb: take someone to ...

Because that means something slightly different.

• 子供と動物園に行きます = I go to the zoo with the child
• 子供を動物園に連れて行きます = I take the child to the zoo

The second version emphasizes that you are bringing the child along, often with the nuance that the child is under your care or accompanying you because you are taking them.

Japanese often omits the subject when it is clear from context.

So:

• 週末に子供を動物園に連れて行きます

can naturally mean:

• I will take the child to the zoo this weekend
• We will take the child to the zoo this weekend

depending on context.

In Japanese, leaving out obvious information is very normal.

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

So 連れて行きます can mean:

• take (habitual or general)
• will take (future)

Because the sentence includes 週末に, it is understood as a future action:

• will take the child to the zoo this weekend

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

So 子供 can mean:

• a child
• children

The exact meaning depends on context.

If the speaker wants to make plural especially clear, they might say:

• 子供たち = children

But 子供 by itself is very common and perfectly natural.

Japanese does not have articles like a, an, or the.

That means 子供 could mean:

• a child
• the child
• children
• the children

And 動物園 could mean:

• a zoo
• the zoo

Context tells you which one is intended.

Sometimes yes, but 週末に is very standard and easy for learners to use.

With time expressions, Japanese is a bit flexible:

• Some time words often appear without に
• Others often take に

For 週末, many speakers do say 週末に, and it sounds very natural here.

So for learning purposes, 週末に is a good choice.

The dictionary form is 連れて行く.

Breakdown:

• 連れて = て-form of 連れる
• 行く = dictionary form of to go

Polite form:

• 連れて行きます

Dictionary/plain form:

• 連れて行く

Past polite form:

• 連れて行きました

Negative polite form:

• 連れて行きません

Normally, Japanese is written without spaces:

• 週末に子供を動物園に連れて行きます

Spaces are often added in teaching materials to make it easier for beginners to see the parts of the sentence.

So the spaced version is helpful for learning, but the normal written form does not use spaces.

Yes. If you want to make the topic explicit, you can say:

• 私は週末に子供を動物園に連れて行きます

This means As for me, I’ll take the child to the zoo this weekend.

You could also mark another topic depending on what you want to emphasize. But in everyday Japanese, leaving the topic out is often perfectly natural if it is already understood.

A useful way to see it is:

• [Time] に [Person] を [Place] に 連れて行きます

So:

• 週末に = time
• 子供を = person being taken
• 動物園に = destination
• 連れて行きます = take someone there

This is a very common pattern you can reuse:

• 友達を駅に連れて行きます = I’ll take my friend to the station.
• 弟を病院に連れて行きます = I’ll take my younger brother to the hospital.
