Ais itu sejuk.

In Malay, demonstratives like ini and itu normally come after the noun.

So:

• ais itu = that ice / the ice
• buku ini = this book
• rumah itu = that house

This is the normal Malay pattern, even though English puts this/that before the noun.

Malay often leaves out the verb to be in simple sentences like this.

So English:

• The ice is cold

becomes Malay:

• Ais itu sejuk

There is no separate word for is here. This is completely normal Malay grammar.

Normally, no. Ais itu sejuk is the natural form.

In Malay, adalah is not usually used before an adjective like sejuk.

So:

• Ais itu sejuk = natural
• Ais itu adalah sejuk = unnatural or overly influenced by English

A useful rule:

• with adjectives, just say the adjective directly
• do not add is-type words just because English would

It can feel like either one, depending on context.

In many cases, itu literally means that. But in actual use, it can also make something sound specific or already known, which is why it is sometimes translated as the.

So ais itu could be understood as:

• that ice
• the ice

The exact best English translation depends on the situation.

Sejuk is an adjective meaning cold.

But in Malay, adjectives can act directly as the predicate of a sentence, so sejuk is doing the job that is cold does in English.

So in Ais itu sejuk:

• Ais itu = subject
• sejuk = predicate adjective

Yes. The structure is very normal:

• Ais itu = the noun phrase
• sejuk = the description

So the sentence pattern is basically:

• [noun phrase] + [adjective]

Examples:

• Air itu panas = The water is hot
• Rumah itu besar = The house is big
• Bilik ini bersih = This room is clean

Yes, you can, but the meaning becomes less specific.

• Ais itu sejuk = that/the ice is cold
• Ais sejuk = cold ice, or possibly ice is cold depending on context

Without itu, it may sound more general or more like a noun phrase than a full sentence. So if you want to point to a specific piece of ice or a specific serving of ice, itu is helpful.

Malay does not have articles that work exactly like English a, an, and the.

Instead, Malay usually relies on:

• context
• word order
• demonstratives like ini and itu
• sometimes classifiers or other markers

So learners often want to match every English article with a Malay word, but that usually does not work one-to-one.

You use tidak before the adjective:

• Ais itu tidak sejuk = The ice is not cold

Use tidak for adjectives and verbs.

Do not use bukan here.
Bukan is usually used to negate nouns or identities, not adjectives.

A simple way is just to use question intonation:

• Ais itu sejuk? = Is the ice cold?

A more formal way is:

• Adakah ais itu sejuk?

Both are possible, but the intonation-based version is very common in everyday speech.

A simple approximate pronunciation is:

• ais ≈ English ice
• itu ≈ ee-too
• sejuk ≈ suh-jook

A few notes:

• The j in sejuk sounds like the j in jam
• The first e in sejuk is a weak vowel, like uh
• In many accents, the final k may sound very light or cut off

So the whole sentence is roughly:

ice ee-too suh-jook

Yes. Ais is a normal Malay word, even though it comes from English ice.

Malay has many loanwords, and once they are commonly used, they are treated as regular Malay vocabulary.

You will also see ais in everyday expressions such as:

• ais krim = ice cream
• air ais = iced water / water with ice
