Pendawaian itu rosak.

Malay often leaves out the verb to be when describing something.

So where English says:

• The wiring is damaged

Malay simply says:

• Pendawaian itu rosak

This is completely normal. In sentences like this, the structure is basically:

• noun + description

Here:

• pendawaian itu = the wiring / that wiring
• rosak = damaged / broken / faulty

So rosak works as the description without needing a separate word for is.

Pendawaian means wiring.

It comes from the root word:

• dawai = wire

The word pendawaian is a derived noun. Very roughly, it refers to:

• the system of wiring
• the act or result of wiring
• electrical wiring in a building, machine, etc.

So compared with dawai:

• dawai = a wire
• pendawaian = wiring / wired system / electrical wiring

This makes pendawaian sound more technical or formal than just wayar or dawai.

In Malay, demonstratives like ini (this) and itu (that) usually come after the noun.

So:

• pendawaian itu = that wiring / the wiring
• rumah itu = that house
• buku ini = this book

This is different from English, where this and that come before the noun.

So you should think of the Malay pattern as:

• noun + ini/itu

not

• ini/itu + noun

It literally means that, but in many sentences it can feel a lot like the in English.

In Pendawaian itu rosak, itu could suggest:

• that wiring is damaged
• the wiring is damaged

Which English translation sounds best depends on context.

Malay does not have a direct article system like English the and a/an, so words like itu are often used when the speaker is referring to something specific and identifiable.

So in real usage, itu may sound less strongly demonstrative than English that sometimes does.

It is often best understood as a stative word in Malay: it describes a state, but it can behave in ways that overlap with what English speakers think of as adjectives and verbs.

In English, we might say:

• The wiring is damaged
  or
• The wiring broke / has gone bad

Malay uses rosak very naturally for this idea.

So in learner-friendly terms, you can treat rosak as meaning:

• damaged
• broken
• faulty
• not working properly

You do not need a separate word like is before it.

Examples:

• Telefon itu rosak. = The phone is broken.
• Kereta saya rosak. = My car is broken / has broken down.

Yes, it is natural, especially in technical or formal contexts.

But in everyday speech, people might often use a simpler noun depending on what exactly they mean, for example:

• Wayar itu rosak. = That wire is damaged.
• Pendawaian rumah itu rosak. = The house wiring is damaged.
• Sistem pendawaian itu rosak. = That wiring system is damaged.

So:

• pendawaian sounds more technical: wiring
• wayar/dawai sounds more like an individual wire

If the sentence is about electrical installation or internal wiring, pendawaian is a good choice.

Normally, no.

The standard order is:

• Pendawaian itu rosak

because itu usually follows the noun it modifies.

So:

• pendawaian itu = that wiring

not:

• itu pendawaian

Malay does allow different word orders in some special contexts for emphasis, but for a straightforward learner sentence, you should stick with:

• noun + itu + description

Yes, it can be possible, but it changes the feel.

• Pendawaian itu rosak = the/that wiring is damaged
• Pendawaian rosak = wiring is damaged / damaged wiring / the wiring is damaged, depending on context

Without itu, the phrase can sound less specifically anchored to one clearly identified thing. Malay often relies on context more than English does.

So if you are talking about some known wiring, pendawaian itu rosak is clearer.
If the context already makes it obvious, pendawaian rosak may still be understood.

You would usually use tidak before rosak:

• Pendawaian itu tidak rosak.

This means:

• The wiring is not damaged.

A useful rule:

• tidak is used with verbs and adjectives/stative words
• bukan is used mainly for noun identification

So here:

• rosak takes tidak, not bukan

Correct:

• Pendawaian itu tidak rosak.

Not the normal choice:

• Pendawaian itu bukan rosak.

A natural yes/no question would be:

• Pendawaian itu rosak?

In speech, Malay often forms yes/no questions just by using statement word order with questioning intonation.

You could also say:

• Adakah pendawaian itu rosak?

This is more formal.

So:

• Pendawaian itu rosak? = natural, common
• Adakah pendawaian itu rosak? = more formal or written

This is a very common question because English often uses broken for many different situations.

• rosak = damaged, faulty, not functioning properly
• pecah = cracked, shattered, burst, broken into pieces

So for wiring, rosak is the right choice because wiring usually becomes faulty or damaged, not shattered.

Examples:

• Telefon itu rosak. = The phone is broken / not working.
• Cermin itu pecah. = The glass is broken / shattered.

So for electrical systems, machines, devices, wiring, and appliances, rosak is very common.

A simple learner-friendly pronunciation is:

• pen-da-wai-an

Roughly:

• pen as in pen
• da as in duh but shorter and clearer
• wai like English why
• an like un in a very light way, or ahn depending on accent

Malay pronunciation is usually quite regular, and each written vowel is normally pronounced.

So try saying it in four parts:

• pen | da | wai | an

Yes, if you mean this wiring instead of that wiring.

• Pendawaian ini rosak. = This wiring is damaged.
• Pendawaian itu rosak. = That wiring is damaged.

Again, the demonstrative comes after the noun:

• pendawaian ini
• pendawaian itu

not before it.
