Căn hộ bị mất nước.

Căn hộ means apartment or flat. It refers to one housing unit in a larger building.

• căn is often used as a classifier-like element for rooms or housing units
• hộ relates to a household/unit

Together, căn hộ is the standard word for apartment.

Bị marks that something happened to the subject in an unfortunate, negative, or unwanted way.

So in Căn hộ bị mất nước, bị shows that the apartment is affected by a problem: the water is gone / the water supply has been lost.

English does not always translate bị directly, but it often gives a sense like:

• was affected by
• ended up with
• suffered

So the sentence feels more like The apartment has had its water cut off or The apartment lost water service, not just a neutral statement.

Yes. Literally, mất means lose and nước means water.

But in real usage, mất nước can mean different things depending on context:

• with a place/building: the water supply is out
• with a person/body: to be dehydrated
• in other contexts, it can even mean something else entirely

In Căn hộ bị mất nước, since an apartment cannot be dehydrated, the natural meaning is the apartment has no running water / the water supply is cut off.

Vietnamese often expresses this idea more compactly than English.

Instead of saying something like:

• The apartment lost its water supply

Vietnamese commonly says:

• Căn hộ bị mất nước

Listeners understand from context that nước here means the usable water service, not just some physical water sitting somewhere.

This is similar to:

• mất điện = lose electricity / have a power outage
• mất mạng = lose internet connection

Yes, you can. Căn hộ mất nước is understandable and natural in many situations.

The difference is mainly nuance:

• Căn hộ mất nước = the apartment has no water / the apartment lost water
• Căn hộ bị mất nước = the apartment was affected by the problem of losing water, with a clearer negative/adverse feeling

So bị adds a sense of inconvenience or misfortune.

It is passive-like, but not exactly the same as English passive in every case.

The pattern subject + bị + verb/verb phrase often means:

• the subject is on the receiving end of something bad
• something happened to the subject

So Căn hộ bị mất nước is less about formal passive grammar and more about the apartment being adversely affected.

A very literal English passive such as The apartment was lost water would be wrong in English, so it is better to think in terms of adversity marker rather than trying to match it one-for-one with English passive.

Yes, this is understandable and natural. But there are several common ways to express the same idea, including:

• Căn hộ bị mất nước.
• Căn hộ mất nước.
• Căn hộ bị cúp nước.
• Căn hộ không có nước.

Nuance:

• bị mất nước = the water is gone; somewhat formal/neutral, with a negative effect
• bị cúp nước = the water was cut off; often sounds like the supply was shut off
• không có nước = there is no water; very straightforward

Here, nước means the general running water supply to the apartment.

It does not usually specify:

• hot water vs. cold water
• drinking water vs. tap water

It simply means the apartment does not currently have normal water service.

If you needed to be more specific, Vietnamese would add more words.

Yes. With a person or body, mất nước commonly means dehydrated.

For example:

• Anh ấy bị mất nước. = He is dehydrated.

But with căn hộ, that reading does not make sense, so context forces the meaning water outage / no water supply.

This is a good example of how Vietnamese meaning often depends strongly on the noun being used.

The structure is:

Căn hộ + bị + mất nước

• Căn hộ = subject
• bị = marker of an adverse situation
• mất nước = lose water / have water service lost

So the overall pattern is:

subject + bị + problem/event

This pattern is very common in Vietnamese for unpleasant situations.

Examples:

• Nhà tôi bị mất điện. = My house lost power.
• Xe tôi bị hỏng. = My vehicle broke down / was damaged.
• Anh ấy bị ốm. = He got sick.

A rough pronunciation guide is:

căn hộ bị mất nước
≈ guhn haw bih mut noo-uhk

A few notes:

• căn has a short vowel and a level-like tone
• hộ has a heavy falling tone
• bị has a heavy low tone
• mất has a sharp rising/glottalized tone
• nước also has a similar sharp/glottalized tone

The tones matter a lot in Vietnamese, so it is best to learn them from audio if possible rather than relying only on English-style spelling.
