Lọ này bị nứt.

Lọ usually refers to a container such as a jar or bottle-like container, and in some contexts it can also refer to a vase.

The exact English translation depends on what the object actually looks like. Vietnamese often uses broader everyday nouns than English does, so lọ này could be translated as:

• this jar
• this bottle
• this vase

depending on the situation.

It is different from some other common container words:

• chai = bottle
• bình = bottle, flask, pitcher, vase, container
• hũ = jar, pot, small container

So lọ is a normal, natural word here, but the best English word depends on context.

In Vietnamese, demonstratives like this and that usually come after the noun.

So:

• lọ này = this jar / this bottle
• lọ kia = that jar / that bottle

This is a very common Vietnamese word order pattern:

• nhà này = this house
• người đó = that person
• xe kia = that car

So lọ này is the normal Vietnamese way to say this jar.

Bị often marks something as happening in a way that is unfavorable, negative, or undesired.

In Lọ này bị nứt, it suggests:

• the jar has ended up in a bad condition
• being cracked is an unfortunate state

So the sentence does not just describe a crack; it presents the crack as a problem or damage.

A very literal way to think of it is something like:

• This jar got cracked
• This jar is cracked (with a negative/damaged nuance)

Yes, you can, but the nuance changes.

• Lọ này bị nứt = This jar is cracked / has gotten cracked, with a clear sense of damage or an unfortunate result.
• Lọ này nứt = This jar is cracked / has a crack.

Without bị, the sentence is a bit more neutral and direct. With bị, it more strongly highlights that this is an unwanted condition.

In everyday speech, both can be possible, but bị nứt is especially common when talking about damage.

Not necessarily.

Bị does not automatically mean the doer is mentioned or even known. It mainly signals that something bad happened to the subject.

So Lọ này bị nứt can mean:

• it got cracked somehow
• it has become cracked
• it is in a damaged state

It does not require the sentence to say who caused it.

If you want to mention the cause, you can add more information, for example:

• Lọ này bị nứt vì rơi xuống đất. = This jar got cracked because it fell on the floor.

Nứt means cracked or to crack. It usually means there is a line or split in the object, but the object may still be in one piece.

Compare:

• nứt = cracked
• vỡ = broken, shattered
• bể = broken/burst, often used for glass, dishes, containers, tanks, etc.

Examples:

• Cốc bị nứt. = The cup is cracked.
• Cốc bị vỡ. = The cup is broken/shattered.
• Kính bị bể. = The glass is broken.

So nứt is less severe than vỡ or bể. A cracked object may still exist as one object, while a broken one may not.

It could be there, but it is not required.

Vietnamese often uses classifiers, and cái is a very common general classifier for objects. So you might hear:

• Cái lọ này bị nứt.

But in many situations, especially when the noun is already clear and natural on its own, people simply say:

• Lọ này bị nứt.

Both are grammatical. The version without cái is perfectly normal.

Very roughly:

• cái lọ này can sound a bit more explicit or conversational
• lọ này is also natural and concise

It is similar to a passive idea, but it is best not to treat it as exactly the same as English passive grammar.

English might say:

• This jar was cracked
• This jar is cracked

Vietnamese uses bị in many situations where English might use a passive structure, especially when the result is negative. But bị is not just a simple passive marker. It also adds that sense of something unfortunate happening to the subject.

So it is helpful to think:

• bị often overlaps with English passive meaning
• but it also carries a negative or affected nuance

A rough pronunciation guide is:

• lọ ≈ law, but with a heavy low tone and a short, clipped feel
• này ≈ nai / nye depending on accent, with a rising tone
• bị ≈ bee, with a heavy low tone
• nứt ≈ something like nưt, with the Vietnamese ư vowel and a high checked tone

The tones are important:

• lọ = nặng tone
• này = huyền tone
• bị = nặng tone
• nứt = sắc tone

A learner-friendly rhythm is:

• lọ này | bị nứt

If you want to sound natural, make sure lọ and bị are not flat; they have a heavy, low tone.

Yes, very often.

Adding rồi can make it sound more like:

• This jar has cracked already
• This jar is cracked now
• The jar ended up cracked

So:

• Lọ này bị nứt. = This jar is cracked.
• Lọ này bị nứt rồi. = This jar is cracked now / has already cracked.

Rồi often adds a sense of a new resulting state or completed change, so it is very common in everyday speech when noticing damage.

It means The jar is cracked.

The subject of the sentence is lọ này = this jar. The predicate is bị nứt = is cracked / got cracked.

So the sentence describes the condition of the jar itself.

If you wanted to talk about a crack as a noun, you would need a different structure, for example:

• Lọ này có vết nứt. = This jar has a crack.
• Có một vết nứt trên lọ này. = There is a crack on this jar.

So bị nứt describes the object as cracked, not the crack as a separate thing.
