Kelajuan data itu tinggi.

In Malay, you often do not need a verb like is / am / are between a subject and an adjective.

So:

• Kelajuan data itu tinggi
• literally: That data speed high
• natural English: That data speed is high / The data speed is high

This is very normal in Malay. Adjectives can act as the predicate by themselves.

Itu usually means that, but in many sentences it also helps make a noun phrase definite, so it can feel like the in English.

In this sentence:

• kelajuan data itu = that data speed / the data speed

Malay often puts itu after the noun phrase it refers to, not before it like English that.

So compare:

• English: that data speed
• Malay: kelajuan data itu

Because demonstratives in Malay normally come after the noun.

Pattern:

• rumah itu = that house
• kereta itu = that car
• kelajuan data itu = that data speed

So this is standard Malay word order.

In Malay, the main noun usually comes first, and the word modifying it comes after.

So:

• kelajuan data = data speed
• literally: speed of data

This is a very common Malay pattern, similar to an of relationship in English:

• harga makanan = price of food
• kualiti air = quality of water
• kelajuan data = speed of data

So data is specifying what kind of speed we mean.

Kelajuan is a noun meaning speed.

It is related to laju, which means fast.

A useful pattern in Malay is that ke-...-an can form nouns:

• laju = fast
• kelajuan = speed

So here:

• kelajuan = speed
• tinggi = high

That gives the idea the speed is high.

Good question. Both relate to speed, but they are used differently.

• cepat = fast / quick
• tinggi = high

In Malay, for things like speed, rate, level, amount, price, it is very natural to describe them as high or low:

• kelajuan tinggi = high speed
• harga tinggi = high price
• kadar tinggi = high rate

So Kelajuan data itu tinggi means the data speed is high, not that the speed itself is quick.

If you used cepat, it would sound less natural with kelajuan because kelajuan is already the noun speed.

No. Tinggi can mean tall/high in both physical and abstract senses.

Examples:

• bangunan itu tinggi = that building is tall
• suhu tinggi = high temperature
• harga tinggi = high price
• kelajuan tinggi = high speed

So in this sentence, tinggi is being used in an abstract sense: high speed.

Yes, you can, but the meaning changes slightly.

• Kelajuan data itu tinggi = The/that data speed is high
• Kelajuan data tinggi = Data speed is high / The data speed is high (more general or less specifically marked)

Adding itu makes the noun phrase more definite and often points to something already known in the conversation.

In Malay, data usually stays the same whether it is singular or plural. Malay nouns generally do not change form the way English nouns often do.

So data can mean data in a general sense without marking number clearly.

In this sentence, the focus is really on data speed, so number is not especially important.

The structure is:

• Kelajuan data itu = subject noun phrase
• tinggi = predicate adjective

So:

• [Noun phrase] + [adjective]

This is a very common Malay pattern.

Other examples:

• Rumah itu besar = That house is big
• Harga makanan ini mahal = This food price is expensive/high
• Air itu sejuk = That water is cold

So Kelajuan data itu tinggi follows a very normal Malay sentence pattern.

A very literal translation would be:

• Speed data that high

That sounds unnatural in English, but it helps show the Malay structure:

• kelajuan = speed
• data = data
• itu = that / the
• tinggi = high

A natural English version would be:

• The data speed is high
• That data speed is high
• depending on context, even The data rate is high or The internet speed is high

A simple learner-friendly pronunciation is:

• keh-LAH-joo-an

Roughly in syllables:

• ke
• la
• ju
• an

A couple of helpful notes:

• j in Malay sounds like English j in job
• u sounds like oo in food
• the final -an is usually clearly pronounced, not swallowed

So the whole sentence would be said smoothly as:

• keh-LAH-joo-an dah-tah ee-too TEENG-gee

This is only an approximation, but it is a useful starting point.
