Perniagaan itu bukan milikan tunggal; sebaliknya, perniagaan itu ialah perkongsian.

In Malay, bukan is normally used to negate:

• nouns
• noun phrases
• identities/classifications

Here, milikan tunggal and perkongsian are both noun phrases describing what kind of business it is, so bukan is the correct choice:

• Perniagaan itu bukan milikan tunggal = The business is not a sole proprietorship.

By contrast, tidak is usually used to negate verbs and adjectives, such as:

• tidak besar = not big
• tidak berjalan = not operating / not walking

So in this sentence, bukan fits because the sentence is denying one business type and replacing it with another.

Itu often works like that or the, depending on context.

So perniagaan itu can mean:

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

Malay often uses itu after the noun:

• perniagaan itu = that/the business
• rumah itu = that/the house
• orang itu = that/the person

In this sentence, it helps point to a specific business already known in the conversation.

Malay often repeats the noun instead of replacing it with a pronoun like it. So:

• Perniagaan itu bukan milikan tunggal; sebaliknya, perniagaan itu ialah perkongsian.

sounds natural and clear.

In English, we would usually avoid repetition:

• The business is not a sole proprietorship; instead, it is a partnership.

But in Malay, repeating perniagaan itu is perfectly normal, especially in formal or careful writing.

You could sometimes omit the second perniagaan itu if the meaning is very clear, but the repeated version is more explicit and polished.

Sebaliknya means instead, rather, or on the contrary, depending on context.

In this sentence, it introduces the correct alternative after rejecting the first possibility:

• bukan milikan tunggal; sebaliknya ...
• not a sole proprietorship; instead ...

It is a formal and very useful linking word in writing and speech.

Other examples:

• Dia bukan guru; sebaliknya, dia doktor.
  • He is not a teacher; instead, he is a doctor.

So here, sebaliknya marks a contrast and replacement.

Both ialah and adalah can often be translated as is, but in standard Malay they are used differently.

A simple rule:

• ialah is typically used before a noun or noun phrase
• adalah is more commonly used before an adjective phrase or prepositional phrase

In this sentence:

• perniagaan itu ialah perkongsian

The word after ialah is perkongsian, which is a noun, so ialah is appropriate.

Examples:

• Hobinya ialah membaca.
• Tujuan utama ialah keselamatan.

Learners should know that in everyday usage, people do not always follow this distinction perfectly, but in careful formal Malay, ialah is a good choice here.

Yes. Malay often allows equational sentences without any word equivalent to is.

So you could also say:

• Perniagaan itu bukan milikan tunggal; sebaliknya, perniagaan itu perkongsian.

That is understandable, but ialah makes the sentence sound more formal, explicit, and polished. In explanatory or textbook-style writing, using ialah is very common.

So:

• with ialah = more formal/structured
• without ialah = still grammatical in many contexts, often more direct

Milikan tunggal means sole proprietorship or sole ownership business.

It is made up of:

• milikan = ownership / possession
• tunggal = single / sole

Together, it refers to a business owned by one person.

Depending on context, learners may also see another common term:

• perniagaan milik tunggal

Both refer to a sole proprietorship, though wording can vary.

Perkongsian means partnership or sharing arrangement, depending on context. In a business context, it means partnership.

It comes from the root kongsi, which relates to sharing or jointly owning/using something.

Malay often forms nouns with patterns like per- ... -an, so:

• kongsi -> perkongsian

This turns the idea of sharing/joint participation into an abstract noun: partnership.

So in this sentence:

• perniagaan itu ialah perkongsian
• the business is a partnership

Yes, it sounds fairly formal and written.

Features that make it formal include:

• sebaliknya
• ialah
• the repetition of perniagaan itu
• the business/legal terms milikan tunggal and perkongsian

In casual spoken Malay, someone might say something simpler, such as:

• Perniagaan itu bukan milik tunggal, tapi perkongsian.

That version is more conversational. The original sentence sounds more suitable for explanation, legal/business context, or formal writing.

The semicolon separates two closely related clauses:

• Perniagaan itu bukan milikan tunggal
• sebaliknya, perniagaan itu ialah perkongsian

It shows a strong connection between the two ideas:

1. rejecting one classification
2. giving the correct one

In Malay writing, a comma or even a full stop could also appear depending on style, but the semicolon is a neat formal choice because the two parts are tightly linked.

Yes, but the nuance changes slightly.

• tetapi = but
• sebaliknya = instead / on the contrary

If you use tetapi, the sentence simply shows contrast:

• Perniagaan itu bukan milikan tunggal, tetapi perkongsian.

This is natural and common.

If you use sebaliknya, it sounds a little more formal and emphasizes that the second description replaces the first one:

• not X; instead, Y

So both are possible, but sebaliknya is more precise and formal in this sentence.

Yes, in many contexts learners will encounter milik tunggal as well.

Very roughly:

• milik often means owned by / property of
• milikan is a noun meaning ownership

So both can appear in business-related expressions, though the exact preferred term may depend on style, region, or official wording.

Examples you may see:

• perniagaan milik tunggal
• milikan tunggal

The sentence you were given uses a more noun-based, formal phrasing.

The structure is:

• Perniagaan itu = subject
• bukan milikan tunggal = negative noun predicate
• sebaliknya = contrast marker
• perniagaan itu = repeated subject
• ialah perkongsian = positive noun predicate

So the overall pattern is:

• X bukan Y; sebaliknya, X ialah Z.

This is a useful model you can reuse:

• Benda itu bukan plastik; sebaliknya, benda itu ialah logam.
• Jawapan itu bukan satu alasan; sebaliknya, jawapan itu ialah pengakuan.

It is a formal pattern for correcting or reclassifying something.

No. Perniagaan is a common and correct word for business, especially in the sense of commercial activity or an enterprise.

Learners may also see:

• bisnes = business, more informal/borrowed from English
• syarikat = company
• usaha = enterprise/effort/venture, depending on context

In this sentence, perniagaan is a good standard Malay choice because the sentence is talking about business structure or ownership type.

A more conversational version might be:

• Perniagaan itu bukan milik tunggal, tapi perkongsian.

Or:

• Itu bukan perniagaan milik tunggal; itu perkongsian.

These versions are shorter and less formal.

Compared with the original:

• sebaliknya sounds more formal than tapi
• ialah sounds more formal than leaving it out
• repeating the full noun phrase gives a more official tone

So the original sentence is good for formal writing, while the shorter versions are more typical in everyday conversation.
