Cô hàng xóm nói là thang máy đang bị hỏng.

Cô is a kinship-based form of address, and Vietnamese uses these very often instead of neutral words like woman or lady.

In this sentence, cô hàng xóm means something like the female neighbor or the neighbor lady.
A few important points:

• cô can refer to a woman, often somewhat older than the speaker or treated respectfully
• it can also function like she / auntie / miss, depending on context
• hàng xóm means neighbor or neighboring household

So cô hàng xóm is not just a random noun phrase. It also reflects how Vietnamese naturally refers to people through social relationship and age/respect.

Because adding cô makes the person more specific and natural.

• hàng xóm by itself = neighbor(s) in a general sense
• cô hàng xóm = the female neighbor
• it also sounds more human and conversational, not just like a dictionary label

Vietnamese often adds a kinship term or social title before a role noun:

• anh bạn = male friend
• chị đồng nghiệp = female colleague
• cô hàng xóm = female neighbor

So this is a very normal way to refer to someone.

Yes, often it does by context.

Vietnamese frequently leaves out possessive words like my when they are obvious. If someone says cô hàng xóm nói..., it usually means the neighbor (of mine / of ours) said... unless context suggests otherwise.

This is very common in Vietnamese. The language often relies more on context than English does.

Here, là introduces the content of what was said. It works a lot like English that in reported speech.

So:

• nói là... = say that...

In this sentence:

• Cô hàng xóm nói là thang máy đang bị hỏng
• literally: The neighbor said that the elevator is broken

Important detail: in Vietnamese, là is often optional in this kind of sentence.

You may also hear:

• Cô hàng xóm nói thang máy đang bị hỏng

That is also natural.

No. Very often, it can be omitted.

Compare:

• Cô hàng xóm nói là thang máy đang bị hỏng
• Cô hàng xóm nói thang máy đang bị hỏng

Both are natural. The version with là can sound a bit clearer or slightly more explicit, especially in speech. But it is not mandatory.

So learners should think of là here as a common clause introducer, not something that must always appear.

Đang marks something as ongoing or currently true at the time being discussed.

In many sentences, it is like English be -ing:

• đang ăn = is eating
• đang làm việc = is working

In this sentence, đang does not mean the elevator is actively doing something. Instead, it marks the current state:

• đang bị hỏng = is currently broken / is presently out of order

So đang emphasizes that this is the elevator’s condition right now.

Yes, bị often marks a passive or adverse situation, but its use is broader than English passive be + past participle.

In this sentence, bị suggests that the elevator is in an unfortunate condition:

• bị hỏng = be broken / have broken down / be in a broken state

A useful way to think about bị:

• it often adds a sense of something undesirable happening
• it can mark passive meaning
• it does not always correspond neatly to one English word

So đang bị hỏng is not literally is being broken by someone. It usually means is broken / is out of order.

Yes, it could.

• thang máy đang hỏng
• thang máy đang bị hỏng

Both can be understood as the elevator is currently broken.

The version with bị often makes the problem feel a bit more like an unfortunate state or malfunction. Without bị, the sentence is a little plainer and more direct.

In everyday Vietnamese, both patterns are possible, though which one sounds best can depend on region and context.

Hỏng means broken, damaged, or not functioning properly.

For machines or devices, it often means out of order or not working:

• xe hỏng = the vehicle broke down
• máy tính hỏng = the computer is broken
• thang máy hỏng = the elevator is broken / out of service

So for an elevator, hỏng is very natural.

Depending on context, English translations could be:

• broken
• not working
• out of order
• has broken down

Yes, literally it is made of:

• thang = ladder, stairs, vertical climbing structure
• máy = machine

Together, thang máy means elevator / lift.

Like many Vietnamese compounds, the literal parts do not need to be translated word-for-word in normal usage. You should simply learn thang máy as the standard word for elevator.

The structure is:

• thang máy = subject
• đang = aspect marker
• bị = passive/adversative marker
• hỏng = broken, malfunctioning

So the order is roughly:

subject + aspect + adverse/passive marker + state

This is typical Vietnamese word order. Vietnamese usually does not use a separate verb like English to be in this kind of sentence.

So instead of saying something exactly like the elevator is broken, Vietnamese simply says, in effect:

• elevator + currently + affected by + broken state

Vietnamese does not mark tense the way English does. It relies heavily on context and on words like đang, đã, and sẽ.

In this sentence:

• đang shows the situation is current or ongoing
• there is no separate present-tense verb ending like English is

So the time reference comes mainly from đang and the context of the conversation.

That is why the sentence is naturally understood as something like:

• The neighbor said that the elevator is currently broken
• or ...was currently broken, depending on the larger context

Yes, it sounds natural.

A few very natural variations would also be common:

• Cô hàng xóm nói là thang máy hỏng rồi.
• Cô hàng xóm nói thang máy bị hỏng.
• Cô hàng xóm bảo là thang máy đang hỏng.

These are all close in meaning, with small differences in tone or nuance.

So the original sentence is good Vietnamese and uses several very common patterns:

• a kinship term for a person
• nói là for reported speech
• đang for current state
• bị hỏng for malfunction or breakdown
