Bilik karaoke itu mempunyai katalog lagu.

Itu is a demonstrative, usually meaning that. In Bilik karaoke itu, it points to a specific karaoke room: that karaoke room.

In Malay, demonstratives usually come after the noun, not before it as in English.

• bilik itu = that room
• rumah itu = that house

So:

• Bilik karaoke itu = that karaoke room

That is the normal Malay word order. In English, we say that room, but in Malay the demonstrative comes after the noun phrase:

• bilik itu = that room
• kereta itu = that car
• bilik karaoke itu = that karaoke room

So the pattern is:

noun + itu

If the noun has a modifier, itu still goes at the end of the whole noun phrase:

• bilik karaoke itu
• katalog lagu itu

Mempunyai means to have / possesses. It is a more formal or written-style way to say that something has something.

So:

• Bilik karaoke itu mempunyai katalog lagu. = That karaoke room has a song catalog.

In everyday conversation, many speakers would more often use ada:

• Bilik karaoke itu ada katalog lagu.

Both are understandable, but mempunyai sounds more formal.

Both can often be translated as have, but they are used a bit differently.

mempunyai

• more formal
• common in writing, official language, or careful speech
• directly expresses possession

Example:

• Hotel itu mempunyai 200 bilik. = The hotel has 200 rooms.

ada

• very common in everyday speech
• can mean there is/are or have
• often sounds more natural in casual conversation

Example:

• Hotel itu ada 200 bilik. = The hotel has 200 rooms.

So in your sentence, mempunyai is grammatically fine and slightly formal.

Malay does not normally use articles like a, an, or the in the same way English does.

So:

• katalog lagu can mean a song catalog or the song catalog, depending on context.

In this sentence, English naturally translates it as a song catalog, but Malay does not need a separate word for a.

This is very common in Malay:

• Saya beli buku. = I bought a book / the book (context decides)
• Dia ada kereta. = He/She has a car

Yes, katalog lagu is a noun phrase where the second noun describes the first. Malay often puts nouns together without using a word like of.

So:

• katalog lagu literally = catalog song
• natural English = song catalog or catalog of songs

This pattern is very common in Malay:

• bilik tidur = bedroom (literally sleep room)
• kedai buku = bookstore (literally book shop)
• harga makanan = food price / price of food

So katalog lagu is perfectly normal Malay structure.

Because the normal Malay sentence structure is:

Subject + verb + object

Here:

• Bilik karaoke itu = subject
• mempunyai = verb
• katalog lagu = object

So the sentence follows a very standard pattern:

Bilik karaoke itu mempunyai katalog lagu.

Starting with Itu bilik karaoke... would usually sound different and may suggest a different emphasis or structure. For a basic statement, the given sentence is the natural order.

By itself, Malay nouns do not change form for singular or plural the way English nouns often do.

So bilik karaoke could refer to:

• a karaoke room
• karaoke rooms

However, in this sentence, the presence of itu strongly suggests a specific single room:

• Bilik karaoke itu = that karaoke room

If you wanted to clearly mark plural, Malay could use context, numbers, or reduplication:

• bilik-bilik karaoke itu = those karaoke rooms
• tiga bilik karaoke = three karaoke rooms

Yes, karaoke is a borrowed word that is commonly used in Malay. Malay uses many loanwords, especially for modern things, entertainment, technology, and international concepts.

So bilik karaoke is a normal and natural phrase in Malay.

This is common with other borrowed words too:

• telefon
• internet
• muzik
• hotel

A very common spoken version would be:

• Bilik karaoke itu ada katalog lagu.

That sounds more casual and conversational.

The original sentence:

• Bilik karaoke itu mempunyai katalog lagu.

is still correct, but it sounds more formal, careful, or written.

So you can think of it like this:

• mempunyai = more formal has
• ada = everyday has / there is

Yes. Mempunyai is related to the root punya, which is connected with possession or ownership.

The form mempunyai is a verb built with the prefix mem- plus the root. As a learner, the most useful thing is to recognize that:

• punya is associated with possession
• mempunyai means to have / to possess

In informal Malay, you may also hear punya used differently, for example to show possession in casual speech:

• saya punya buku = my book
  This is colloquial and not the most formal standard form.

But in your sentence, mempunyai is the proper standard verb.

Yes, that is grammatically possible, but the meaning becomes less specific.

• Bilik karaoke itu mempunyai katalog lagu. = That karaoke room has a song catalog.

• Bilik karaoke mempunyai katalog lagu. = A karaoke room / karaoke rooms have a song catalog or karaoke rooms have song catalogs, depending on context.

So itu helps identify a specific room that both speaker and listener know about. Without it, the sentence is more general or less definite.

A simple learner-friendly pronunciation guide is:

Bilik karaoke itu mempunyai katalog lagu
≈ BEE-lik kara-O-kay EE-too mem-poon-YAI kata-LOG LA-goo

A few helpful notes:

• bilik: the i sounds like ee
• karaoke: usually pronounced close to karaoke in English, though local pronunciation may vary
• itu: ee-too
• mempunyai: the final part -nyai is important; ny sounds like the ny in canyon
• lagu: la-goo

Malay pronunciation is generally more consistent than English spelling, so once you learn the sound system, reading becomes easier.
