Perniagaan itu termasuk pemborongan.

In Malay, demonstratives such as ini and itu normally come after the noun, not before it as in English.

So:

perniagaan itu = that business / the business

This is a very common word order pattern in Malay:

• rumah itu = that house
• buku ini = this book
• orang itu = that person

It can feel like either, depending on context.

Its basic meaning is that, but in many real sentences itu also helps make the noun definite, so English may translate it as the. That is why perniagaan itu could be understood as either:

• that business
• the business

The exact choice in English depends on the wider context, not just the Malay sentence by itself.

Here, termasuk means includes or involves as part of it.

So Perniagaan itu termasuk pemborongan means that wholesaling is one part of that business.

A useful thing to know is that termasuk can work in slightly different ways:

• X termasuk Y = X includes Y
• Y termasuk dalam X = Y is included in X

So in your sentence, the business is the larger thing, and pemborongan is one of its components.

Malay often does not need a separate word like is in the way English does.

In this sentence, termasuk is already the main verb, so nothing extra is needed. Malay also does not use a helper verb like does in normal positive statements.

So the structure is simply:

Perniagaan itu + termasuk + pemborongan

That is a complete and natural sentence in Malay.

Pemborongan means wholesaling or wholesale trade.

It is formed from the root borong, which has the idea of wholesale or buying/selling in bulk. The form pem- ... -an turns it into a noun referring to the activity, field, or practice.

So:

• borong = wholesale / in bulk / to buy in bulk
• pemborongan = wholesaling, wholesale trade

This kind of word formation is very common in Malay.

They are related, but they do not mean the same thing.

• pemborongan = wholesaling, wholesale trade, the activity or sector
• pemborong = a wholesaler or the person/company doing the wholesaling

So:

• pemborongan is the business activity
• pemborong is the actor

That final -an makes a big difference.

Because pemborongan is the noun that specifically refers to the activity or sector of wholesale trade.

The root borong is more flexible and can mean things like:

• wholesale
• in bulk
• to buy or sell wholesale

But in this sentence, Malay wants a clear noun meaning wholesaling. That is why pemborongan fits better.

So termasuk pemborongan sounds like includes wholesaling, while termasuk borong would sound incomplete or unnatural in this context.

A natural way to say that is:

Pemborongan termasuk dalam perniagaan itu.

Here the structure changes:

• pemborongan becomes the subject
• termasuk dalam means is included in
• perniagaan itu is the larger category

So the two sentences are closely related, but the focus is different:

• Perniagaan itu termasuk pemborongan = The business includes wholesaling.
• Pemborongan termasuk dalam perniagaan itu = Wholesaling is included in that business.

Usually perniagaan means business, trade, or a business activity/enterprise, not necessarily a legal company.

If you specifically mean company as an organization or corporation, syarikat is often the more exact word.

So:

• perniagaan = business, trade
• syarikat = company

In your sentence, perniagaan itu is best understood as that business or the business, not automatically that company.
