A very common Chinese pattern is:

Subject + adverb + verb + destination/place + 了

So here:

• 货车 = the truck
• 已经 = already
• 到 = arrive / reach
• 新居 = the new home / new residence
• 了 = indicates a new situation or completed event

Chinese usually puts adverbs like 已经 before the main verb, so 已经 comes before 到.

Here, 到 is a verb, not the English-style preposition to.

It means to arrive at, to reach, or to get to.

So:

• 到新居 = arrive at the new home
• not literally just to the new home

This is why Chinese does not need a separate word like English to in this sentence.

Because 到 itself already expresses movement toward and arrival at a place.

So Chinese says:

• 到新居 = arrive at the new home

not:

• 到在新居 ✘

You use 在 for location in other kinds of sentences, such as describing where something is:

• 货车在新居外面。 = The truck is outside the new home.

But after 到, the destination normally comes directly after it.

已经 means already.

It tells us that the arrival has happened by now, often with a feeling like:

• it happened sooner than expected, or
• it is now a completed fact

Without 已经, the sentence would still be grammatical:

• 货车到新居了。

But 已经 makes the sense of already explicit.

In this sentence, 了 marks a new situation or a completed event relevant now.

So 货车已经到新居了 means something like:

• the truck has arrived at the new home now
• the situation has changed: before it had not arrived, now it has

Sentence-final 了 is very common when reporting that something has now happened.

Chinese can place 了 in different positions depending on structure and emphasis.

Here, sentence-final 了 is very natural because it highlights the new state:

• 货车已经到新居了。

This feels like: The truck has arrived at the new home now.

You may also hear forms with 到了, but in this sentence, final 了 is especially natural for announcing the completed arrival as a current situation.

Yes, very often.

This is a common combination in Chinese:

• 已经 + verb + 了

It expresses that something has already happened.

Examples:

• 我已经吃了。 = I’ve already eaten.
• 他已经回家了。 = He has already gone home.
• 货车已经到新居了。 = The truck has already arrived at the new home.

So for learners, 已经 ... 了 is a useful pattern to remember.

新居 means new residence or new home, but it is a bit more formal or literary than 新家.

• 新居: somewhat elegant, often seen in congratulations about moving
• 新家: more everyday and conversational

So this sentence sounds a little more polished than if it used 新家.

In daily speech, many people would more naturally say:

• 货车已经到新家了。

But 新居 is still perfectly understandable and correct.

货车 literally means cargo truck / truck for carrying goods.

Depending on context, it could be understood as:

• a truck
• a delivery truck
• a moving truck carrying belongings

Because the sentence mentions 新居, many learners will infer it is probably the truck carrying things to the new home.

If you wanted to be more specific, you could say something like a moving truck, but 货车 works if the context is clear.

Yes. In English, arrive at, reach, and sometimes get to can all work.

That is because 到 covers the idea of reaching a destination.

So depending on translation style, you might see:

• The truck has already arrived at the new home.
• The truck has already reached the new home.
• The truck has already gotten to the new home.

The Chinese is the same.

You would usually say:

• 货车还没到新居。
• 货车还没有到新居。

This means The truck hasn’t arrived at the new home yet.

A key point: when negating a completed action like this, Chinese normally uses 没(有), not 不.

So:

• 没到 = has not arrived
• 不到 usually does not mean the same thing here

Also notice that in this negative sentence, 了 is usually not used.

Yes.

You can say:

• 货车到新居了。

This still means the truck has arrived at the new home.

Adding 已经 just makes already explicit. If the context already suggests that idea, speakers may leave it out.

In a way, both.

Chinese does not mark tense the same way English does. Instead, this sentence focuses on completion and current relevance.

So 货车已经到新居了 means:

• the arrival happened, and
• now the truck is there

That is why English often translates it with the present perfect:

• The truck has already arrived at the new home.

But depending on context, a simple past translation may also be possible.

Sometimes learners try to do that mechanically, but you should be careful.

Chinese allows several patterns with 了, and not every version has exactly the same feel.

For this sentence, 货车已经到新居了 is a very natural choice because it emphasizes the new state of arrival.

It is best to learn the whole pattern as it appears here rather than thinking that 了 must always attach directly to the verb.
