Cửa hàng nói đơn hàng này đã được giao rồi, nhưng hàng xóm của tôi chưa thấy ai đến.

Cửa hàng literally means shop or store. In this sentence, it is the one giving the information, so it works as the subject of nói.

Vietnamese often lets businesses, organizations, or places act as the grammatical subject, just like English does in sentences such as The store said the package was delivered.

So:

• Cửa hàng nói... = The shop/store says...

Even though an actual employee said it, Vietnamese can simply use cửa hàng.

In Vietnamese, after verbs like nói or bảo, the following clause often comes directly after it without a separate word for that.

So:

• Cửa hàng nói đơn hàng này đã được giao rồi
• literally: The store says this order has already been delivered

You can sometimes add là or rằng in other contexts, but it is very common to leave them out.

Compare:

• Cửa hàng nói đơn hàng này đã được giao rồi = natural
• Cửa hàng nói rằng đơn hàng này đã được giao rồi = also possible, slightly more formal

Đơn hàng means order or purchase order.
Này means this.

So:

• đơn hàng này = this order

In Vietnamese, demonstratives like này usually come after the noun:

• cuốn sách này = this book
• người này = this person
• đơn hàng này = this order

That word order is different from English.

This part has several pieces:

• đã = marks a completed action in the past, often like already or a past/perfect marker
• được = here it helps form a passive meaning
• giao = deliver, hand over
• rồi = indicates completion, often already

So:

• đã được giao rồi = has already been delivered

A useful breakdown:

• giao = deliver
• được giao = be delivered
• đã được giao = was/has been delivered
• đã được giao rồi = has already been delivered / was delivered already

No. Được has more than one job in Vietnamese.

In this sentence, được is mainly part of a passive structure:

• đơn hàng này đã được giao rồi = this order has been delivered already

In other sentences, được can mean things like:

• to be allowed to
• to have the chance to
• to receive
• sometimes a positive sense like successfully or beneficially

But here, it is best understood as a passive marker.

Yes, both relate to completion, but they are not exactly identical.

• đã marks that the action happened before now
• rồi emphasizes that the action is completed/already done

Together, they strongly reinforce the idea:

• đã được giao rồi = has already been delivered

Vietnamese often uses both in everyday speech. It may feel repetitive if translated word-for-word, but it is very natural.

Compare:

• đã giao = delivered / had delivered
• giao rồi = already delivered
• đã giao rồi = definitely already delivered, completed

Hàng xóm means neighbor or neighbors, depending on context.
của tôi means of mine / my.

So:

• hàng xóm của tôi = my neighbor or my neighbors

In this sentence, it is probably understood as my neighbor or possibly my neighbors, depending on the situation.

You can also often say:

• hàng xóm tôi

That is less formal and very common in speech.

So both are possible:

• hàng xóm của tôi = a bit fuller, more explicit
• hàng xóm tôi = more conversational

This is an important difference.

• chưa = not yet
• không = not

So:

• chưa thấy ai đến = hasn’t seen anyone come yet
• không thấy ai đến = didn’t see anyone come or doesn’t see anyone come, depending on context

In this sentence, chưa is used because the idea is that, up to now, no one has been seen arriving. It fits the contrast with the store’s claim that delivery already happened.

So chưa is better because it suggests:

• As of now, no one has been seen yet

Ai literally means who, but in negative or incomplete contexts it can also mean anyone or someone, depending on the sentence.

Here:

• chưa thấy ai đến
• literally: not yet saw who come
• natural meaning: hasn’t seen anyone come

Because the sentence is negative-like with chưa, ai is interpreted as anyone.

Similar patterns:

• Tôi không thấy ai cả = I don’t see anyone
• Có ai ở đây không? = Is anyone here?
• Ai đến vậy? = Who is coming?

So the exact meaning of ai depends on context.

Yes, đến often means come, arrive, or reach.

In this sentence:

• thấy ai đến = see anyone come / arrive

Because this is about a delivery, đến means someone came to the house or arrived there.

So the sense is:

• my neighbor hasn’t seen anyone show up

Vietnamese often leaves subjects unstated when another word already covers the meaning.

Here, ai already provides the idea of anyone/someone, so there is no need for an extra pronoun.

• thấy ai đến = see anyone come

Adding another subject would be unnecessary. Vietnamese is often more compact than English in structures like this.

It has two clauses joined by nhưng:

1. Cửa hàng nói đơn hàng này đã được giao rồi

   • The store says this order has already been delivered

2. nhưng hàng xóm của tôi chưa thấy ai đến

   • but my neighbor hasn’t seen anyone come

So the pattern is:

• Clause 1 + nhưng + Clause 2

This is a very common way to show contrast in Vietnamese, just like but in English.

Yes. Vietnamese often allows small variations without changing the core meaning.

Some natural alternatives:

• Cửa hàng nói đơn hàng này giao rồi, nhưng hàng xóm tôi chưa thấy ai đến.
• Cửa hàng nói đơn hàng này đã giao rồi, nhưng hàng xóm tôi chưa thấy ai tới.
• Cửa hàng bảo đơn hàng này đã được giao rồi, nhưng hàng xóm tôi chưa thấy ai đến.

A few notes:

• bảo can replace nói in many everyday contexts
• tới can replace đến
• hàng xóm tôi is a more casual version of hàng xóm của tôi

The original sentence is completely natural and clear.
