Najis itu busuk.

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

So:

• najis itu = that excrement / the excrement
• buku ini = this book
• rumah itu = that house

This is normal Malay word order.

It often literally means that, but in real usage it can also make a noun feel specific or definite, so in many contexts najis itu can be understood as the excrement.

That means the sentence could feel like:

• That excrement is smelly
• or The excrement is smelly

Which one sounds better in English depends on context.

Malay often leaves out the present-tense copula is / am / are.

So:

• Najis itu busuk literally looks like Excrement that smelly
• but it naturally means That excrement is smelly

This is very common in Malay. You do not need a separate word for is in simple sentences like this.

Busuk is basically an adjective meaning rotten, smelly, or stinky, depending on context.

In Malay, adjectives can act directly as the predicate of a sentence, so:

• Najis itu busuk = That excrement is smelly

So even though busuk is an adjective, it works in a way that English would often translate with is + adjective.

This is a very useful distinction:

• Najis itu busuk = That excrement is smelly

  • full sentence
  • busuk is the predicate

• najis busuk itu = that smelly excrement

  • noun phrase, not a full statement by itself
  • busuk describes najis inside the noun phrase

So word order changes the structure and meaning.

Yes. Najis busuk means smelly excrement.

Compare:

• najis busuk = smelly excrement
• najis itu busuk = the excrement is smelly

The first is a noun phrase.
The second is a complete sentence.

Not always. Busuk can mean several related things, such as:

• rotten
• foul-smelling
• stinking
• sometimes figuratively bad or corrupt

For food, busuk often means rotten.
For something like najis, it naturally comes across as smelly or stinking.

So the exact English translation depends on what is being described.

It is understandable, but its tone is a bit more formal, polite, or sometimes religious/legal than the most casual everyday words.

Depending on context, najis can mean:

• excrement / feces
• or more broadly impurity, especially in Islamic usage

So in some contexts it sounds more formal than a casual everyday word like poop.

A simple approximate pronunciation is:

• Najis → NA-jis or na-JIS with a soft j like in jam
• itu → ee-too
• busuk → boo-sook

A helpful rough guide:

nah-jis ee-too boo-sook

In many Malay accents, the final k in busuk may sound very light or like a cut-off stop rather than a strong English k.

Yes. That would mean This excrement is smelly.

The difference is:

• ini = this
• itu = that

Both come after the noun:

• najis ini
• najis itu

So the sentence changes depending on whether the thing is felt to be near or farther away, physically or mentally.

Yes, it is grammatically natural.

It is a very simple and direct sentence:

• najis itu = the specific excrement
• busuk = smelly

So Najis itu busuk is a normal basic Malay sentence structure. The only thing that may feel unusual is the topic itself, not the grammar.
