Salinan diperakui itu menunjukkan nombor cukai.

Diperakui comes from the root akui, which has the basic idea of acknowledge, recognize, or confirm.

The prefix di- usually marks the passive in Malay, so diperakui means something like:

• acknowledged
• confirmed
• certified
• officially recognized

In this sentence, salinan diperakui means a certified copy.

So although the most natural English translation is certified copy, the Malay structure is closer to copy that has been certified/confirmed.

In Malay, demonstratives like ini (this) and itu (that/the) normally come after the noun phrase, not before it.

So:

• salinan itu = that copy / the copy
• salinan diperakui itu = that certified copy / the certified copy

This is different from English, where we say that certified copy, with that before the noun.

Malay pattern:

• noun + modifier + itu/ini

Examples:

• rumah besar itu = that big house
• dokumen rasmi itu = that official document
• salinan diperakui itu = that certified copy

Yes. Salinan diperakui itu functions as a single noun phrase: the/that certified copy.

You can break it down like this:

• salinan = copy
• diperakui = certified / officially confirmed
• itu = that / the

Together:

• salinan diperakui itu = that certified copy

So the sentence structure is:

• Salinan diperakui itu = subject
• menunjukkan = verb
• nombor cukai = object

Because menunjukkan is the main verb, and it already means shows or is showing.

The sentence is not saying:

• The certified copy is the tax number

It is saying:

• The certified copy shows the tax number

So there is no need for is here.

Malay often does not use a verb meaning to be in the same way English does, especially in equational sentences, but in this sentence that issue does not really come up because there is already a full lexical verb: menunjukkan.

Menunjukkan is the form that means to show something.

It comes from the root tunjuk (point, show, indicate) plus affixes.

Very roughly:

• menunjuk can mean to point
• menunjukkan usually means to show / to indicate something more explicitly

In this sentence, menunjukkan nombor cukai means:

• shows the tax number
• indicates the tax number

So -kan helps make it the natural verb for showing an object.

Malay often puts nouns together very directly, where English might use of, for, or a more complex phrase.

So:

• nombor cukai = tax number
• literally, something like tax number

This is a very common pattern in Malay:

• kad pengenalan = identity card
• bilik mesyuarat = meeting room
• nombor telefon = telephone number
• nombor cukai = tax number

You do not need a word like of here.

It can often feel like either that or the, depending on context.

Strictly speaking, itu is a demonstrative, so its core meaning is that. But in real sentences, Malay often uses itu where English would naturally just say the.

So:

• salinan diperakui itu could be translated as:
  • that certified copy
  • the certified copy

Which one sounds best depends on the wider context.

This is very common in Malay, and learners often notice that itu is sometimes more definite than strongly demonstrative.

It can have several related meanings depending on context, such as:

• certified
• acknowledged
• recognized
• approved
• confirmed

In this sentence, certified is the most natural translation because salinan diperakui is a common official-document type phrase.

But the core meaning is broader than just one English word. It refers to something that has been formally accepted or confirmed.

Yes, you could, and it is grammatically fine.

• salinan diperakui itu
• salinan yang diperakui itu

Both can mean that/the certified copy.

The version without yang is more compact and very natural in Malay, especially in formal or administrative language.

Adding yang makes the modifier feel more explicitly like a relative clause:

• salinan yang diperakui itu = the copy that has been certified

So:

• salinan diperakui itu = more concise
• salinan yang diperakui itu = slightly more explicit

Yes, but that would mean something different.

Compare:

• Salinan diperakui itu menunjukkan nombor cukai.

  • The certified copy shows the tax number.

• Salinan itu diperakui.

  • That copy is certified.

In the original sentence, diperakui describes salinan as part of the noun phrase.

In Salinan itu diperakui, diperakui becomes the main predicate of the clause.

So the word order changes the grammar and the meaning.

Malay does not use articles the way English does.

There is no direct equivalent that works exactly like a/an and the in all cases.

So:

• salinan can mean a copy or the copy, depending on context
• nombor cukai can mean a tax number or the tax number

Malay uses context, word order, and words like itu or ini to show definiteness when needed.

In this sentence:

• salinan diperakui itu is definite because of itu
• nombor cukai is understood from context

Yes, it sounds fairly formal or administrative.

Words like:

• salinan
• diperakui
• menunjukkan
• nombor cukai

are all perfectly normal Malay, but together they sound like something you might see in:

• official paperwork
• government instructions
• legal or tax documents
• formal written explanations

In casual speech, someone might choose simpler wording depending on the situation, but the sentence itself is natural and correct for formal use.
