Jaga kebersihan rumah.

Because this is an imperative sentence: a command or instruction.

In Malay, commands often use just the verb by itself, without saying the subject. So:

• Jaga kebersihan rumah. = Take care of the cleanliness of the house / Keep the house clean.

The understood subject is you, just like in English commands:

• Sit down.
• Be careful.
• Keep the room clean.

Malay simply does the same thing.

Jaga is a verb. Its basic idea is to take care of, to look after, to maintain, or to guard, depending on context.

In this sentence, it means something like:

• maintain
• look after
• take care of

So jaga kebersihan rumah is not literally about guarding the house from danger. It means maintain the house’s cleanliness.

Because in commands, Malay usually uses the base form of the verb.

• jaga = base form
• menjaga = active verb form often used in statements

Compare:

• Dia menjaga kebersihan rumah.
  = He/She maintains the cleanliness of the house.

But for a command:

• Jaga kebersihan rumah.
  = Maintain the cleanliness of the house.

So dropping meN- here is normal and expected.

Kebersihan is a noun meaning cleanliness.

It comes from:

• bersih = clean
• ke- ... -an = a common noun-forming pattern

So:

• bersih = clean
• kebersihan = cleanliness

This pattern often turns an adjective or root into an abstract noun. For a learner, the important thing here is simply:

• kebersihan rumah = the cleanliness of the house

Because in Malay, the main noun usually comes first, and the word modifying it comes after.

So:

• kebersihan rumah

literally works like:

• cleanliness + house

But in natural English, we translate it as:

• the cleanliness of the house
• house cleanliness

This is a very common Malay pattern. Another similar example:

• bilik tidur = bedroom
  literally room sleep

So rumah comes after kebersihan because it specifies whose/what cleanliness is being talked about.

Malay does not normally use articles like a, an, or the the way English does.

So:

• rumah can mean house, a house, or the house
• the exact meaning depends on context

In Jaga kebersihan rumah, English often needs the, but Malay does not.

That is very normal in Malay.

It can depend on context.

Malay often leaves definiteness unstated, so kebersihan rumah could refer to:

• house cleanliness in general
• the cleanliness of the house
• a house’s cleanliness

In a real situation, context tells you which one is meant. If this is a sign in someone’s home, it will usually be understood as the cleanliness of the house or simply keeping the house clean.

Yes. It sounds natural, especially as:

• an instruction
• a reminder
• a sign
• a slogan

It has a concise, slightly formal or instructional tone. That is common in notices and reminders.

In everyday speech, someone might also say things in other ways depending on the situation, but Jaga kebersihan rumah. is definitely normal.

By itself, it is a straightforward instruction. It is not rude, but it is fairly direct.

Malay often makes commands softer by adding words such as:

• tolong = please
• sila = please / kindly

For example:

• Tolong jaga kebersihan rumah.
• Sila jaga kebersihan rumah.

These sound more polite.

Without those words, Jaga kebersihan rumah. sounds like a plain reminder or instruction, which is perfectly fine on a sign or in a household rule.

Not naturally. Even though jaga can sometimes mean guard, that would sound odd in English here.

A better translation is:

• Keep the house clean
• Maintain the cleanliness of the house
• Take care of the house’s cleanliness

So this is one of those cases where a literal translation is possible, but not the best natural English.

Not in the same way.

Jaga kebersihan rumah is the natural way to say maintain the cleanliness of the house.

If you want to express the idea keep the house clean, natural alternatives include:

• Pastikan rumah bersih. = Make sure the house is clean.
• Jaga kebersihan rumah. = Maintain the house’s cleanliness.

But Jaga rumah bersih does not sound like a standard equivalent of the original sentence.

A simple pronunciation guide is:

• Jaga ≈ jah-gah
• kebersihan ≈ kuh-bur-see-han
• rumah ≈ roo-mah

A few helpful points:

• j in Malay sounds like English j in job
• g is always a hard g, like in go
• h is usually pronounced
• stress in Malay is generally not as strong or dramatic as in English

So the whole sentence is roughly:

jah-gah kuh-bur-see-han roo-mah

Yes, jaga is very flexible. It can be used with people, places, things, health, behavior, and more.

For example:

• jaga anak = take care of a child
• jaga rumah = look after the house / guard the house
• jaga kesihatan = take care of one’s health
• jaga kebersihan = maintain cleanliness

So in Jaga kebersihan rumah, jaga is being used in the sense of maintain / take care of rather than guard.
