Perkongsian itu mempunyai dua rakan kongsi.

Because they are two different words built from the same root idea.

• kongsi relates to sharing or being a partner
• perkongsian is a noun meaning something like partnership or sharing arrangement
• rakan kongsi means partner in the business sense

So:

• perkongsian = the partnership
• rakan kongsi = a business partner / partners

This is very common in Malay: one root can produce several related words with different meanings and functions.

Itu means that, but in sentences like this it often works like the in English.

So perkongsian itu means:

• that partnership
• or more naturally in English, the partnership

Malay does not have articles like the or a/an, so words like itu and ini often help specify which thing is being talked about.

Compare:

• perkongsian = a partnership / partnership
• perkongsian itu = that partnership / the partnership

Yes. Both are possible, but they differ in style.

• mempunyai = to have, more formal or written
• ada = often used in everyday speech to express there is/are or have

So these are both possible:

• Perkongsian itu mempunyai dua rakan kongsi.
  More formal, neat written style.

• Perkongsian itu ada dua rakan kongsi.
  More conversational and very natural in speech.

Learners should know that mempunyai is correct and common in formal contexts, but ada is extremely common in daily Malay.

Malay usually follows a basic Subject + Verb + Object/Complement order, much like English.

Here:

• Perkongsian itu = subject
• mempunyai = verb
• dua rakan kongsi = object

So the structure is:

• The partnership
  • has
    • two partners

This word order is very normal in Malay.

In Malay, numbers usually come before the noun.

So:

• dua rakan kongsi = two partners
• tiga syarikat = three companies
• lima orang pekerja = five workers

Putting the number after the noun is generally not how ordinary noun phrases are formed in standard Malay.

It could be added, yes.

For people, the classifier orang is often used:

• dua orang rakan kongsi = two partners

In many real sentences, especially casual or efficient speech, the classifier may be omitted:

• dua rakan kongsi

Both are understandable and acceptable, but:

• dua orang rakan kongsi sounds a bit fuller and more explicit
• dua rakan kongsi is shorter and still very natural

Because rakan kongsi refers to people, orang is the classifier you would use if you include one.

Here it is understood as plural because of dua.

Malay nouns usually do not change form for singular vs. plural the way English nouns do.

So:

• seorang rakan kongsi = one partner
• dua rakan kongsi = two partners

The noun itself stays the same. The number tells you whether it is singular or plural.

Not here. Once you already have a number like dua, you normally do not reduplicate the noun.

So:

• dua rakan kongsi = correct
• dua rakan kongsi-rakan kongsi = not natural
• dua rakan-rakan kongsi = not natural

In Malay, plural meaning can be shown in different ways, and using a number is already enough.

Yes. Depending on context, perkongsian can refer more generally to sharing.

For example:

• perkongsian maklumat = sharing of information
• perkongsian pengalaman = sharing of experiences

But in a business-related sentence like this one, perkongsian is naturally understood as a partnership.

So context decides whether it means:

• sharing
• or partnership

Yes, if the speaker does not need to specify that/the particular partnership.

Compare:

• Perkongsian itu mempunyai dua rakan kongsi.
  That/The partnership has two partners.

• Perkongsian mempunyai dua rakan kongsi.
  A partnership has two partners or the partnership has two partners, depending on context

In real Malay, dropping itu can make the sentence feel more general or less specifically anchored to a known item.

Yes. Mempunyai comes from the same root as punya, which is connected with having/ownership.

Very roughly:

• punya = have / belonging to / own
• mempunyai = to have

In modern Malay:

• mempunyai is the more formal standard verb
• punya is often used differently in everyday speech, and sometimes sounds more colloquial depending on structure

So a learner should recognize the relationship, but not assume they are always interchangeable in every sentence.

It sounds standard and slightly formal, mainly because of mempunyai.

A more everyday spoken version might be:

• Perkongsian itu ada dua rakan kongsi.

The original sentence is perfectly natural, especially in:

• writing
• business contexts
• textbooks
• formal explanation

So if you see this in learning materials, that is completely normal.
