Harga promosi itu rendah.

Here is the breakdown:

• harga = price
• promosi = promotion / promotional
• itu = that or sometimes the, depending on context
• rendah = low

So the structure is basically:

• harga promosi = promotional price
• harga promosi itu = that promotional price / the promotional price
• harga promosi itu rendah = That promotional price is low

In Malay, words often combine very directly like this, without extra linking words.

Malay often leaves out the verb to be in simple sentences with adjectives.

So:

• Harga promosi itu rendah literally looks like Promotional price that low
• but naturally means That promotional price is low

This is completely normal in Malay. When the predicate is an adjective like rendah (low), you usually do not need a word meaning is.

In Malay, adjectives usually come after the noun or noun phrase they describe.

So:

• harga rendah = low price
• harga promosi itu rendah = that promotional price is low

In this sentence, rendah is not inside the noun phrase; it is the predicate describing the whole subject harga promosi itu.

A useful way to see it is:

• Subject: harga promosi itu
• Description: rendah

Itu most basically means that, but in real Malay it can also make a noun phrase more definite, a bit like the in English.

So harga promosi itu can mean:

• that promotional price
• the promotional price

Which one sounds better in English depends on context.

In everyday Malay, itu often helps point to something already known, already mentioned, or visible in the situation.

Malay noun modifiers often come after the main noun.

So:

• harga promosi = literally price promotion
• natural English: promotional price

This is very normal in Malay. The main noun comes first, and the word modifying it often comes after it.

Compare:

• baju sekolah = school uniform / school clothes
• kad kredit = credit card
• harga promosi = promotional price

Not exactly in the same way as English promotional is.

In Malay, a noun like promosi can be used after another noun to modify it. So promosi is still basically a noun, but it functions like a modifier in harga promosi.

This is very common in Malay. You do not always need a separate adjective form.

So instead of changing promosi into a special adjective, Malay simply uses:

• harga promosi = promotional price

This is a very common learner question.

Both can relate to cheap / low in price, but they are not exactly the same:

• rendah = low
  
  • often used for levels, amounts, rates, prices, numbers
• murah = cheap / inexpensive
  
  • often used when talking about something being inexpensive to buy

So:

• harga itu rendah = the price is low
• barang itu murah = the item is cheap / inexpensive

You can sometimes hear harga murah, but harga rendah is especially straightforward when talking about a price level.

It is possible in some contexts, but it sounds less precise than rendah.

Why?

Because murah usually describes the thing being bought as cheap / inexpensive, while rendah more directly describes the price itself as low.

So:

• Harga promosi itu rendah = very natural for The promotional price is low
• Barang promosi itu murah = That promotional item is cheap
• Harga promosi itu murah = understandable, but many learners will sound more natural using rendah for price

Not freely.

The natural order here is:

• Harga promosi itu rendah

That is:

• noun phrase first
• adjective/predicate after it

If you change the order too much, it may become unnatural or mean something else.

For example:

• Rendah harga promosi itu = possible only in special poetic or emphatic styles, not the normal basic order
• Itu harga promosi rendah = unnatural for the meaning intended

So for standard Malay, keep:

• Subject + description
• Harga promosi itu rendah

Yes. You could say:

• Harga promosi rendah

But that feels less definite and may sound more general or headline-like. It could mean something like:

• Promotional prices are low
• The promotional price is low, depending on context

Adding itu makes the phrase more specific:

• harga promosi itu = that/the promotional price

So itu helps point to a particular price.

It is neutral and perfectly normal. It works in both spoken and written Malay.

It is simple, natural Malay:

• no unnecessary formal markers
• no slang
• no special literary style

So it is a good basic sentence pattern to learn.

Normally, no.

You would usually say:

• Harga promosi itu rendah

not:

• Harga promosi itu adalah rendah

In Malay, adalah is often overused by learners. With simple adjective predicates like rendah, it is usually unnecessary and often sounds less natural.

For a basic descriptive sentence, just use:

• noun phrase + adjective

Because itu usually comes at the end of the noun phrase it belongs to.

So:

• harga promosi itu = that promotional price

not:

• harga
  • promosi itu separately

A useful pattern is:

• rumah besar itu = that big house
• kereta baru itu = that new car
• harga promosi itu = that promotional price

This is a very common Malay structure: the noun phrase builds up first, and itu comes at the end of it.
