Geng itu berada di luar.

In Malay, demonstratives like ini (this) and itu (that) usually come after the noun.

So:

• geng itu = that gang / that group
• not itu geng

This is a very common word order pattern in Malay:

• rumah itu = that house
• orang ini = this person

Depending on context, geng itu can also feel like the gang/group, not just strictly that gang.

Geng is a borrowed word from English gang, but in Malay it often has a broader, less negative meaning.

It can mean:

• a group
• a clique
• a bunch of people
• a group of friends

So it does not always sound criminal the way gang often does in English.

In casual speech, geng is very common. Depending on context, it might refer to:

• a friend group
• a team
• a set of people associated with each other

Berada means something like:

• to be located
• to be situated
• to be present in a place

In this sentence, it makes the idea of location more explicit. So berada di luar means to be outside or to be located outside.

It is slightly more formal or careful than simply saying:

• Geng itu di luar.

That shorter version is also natural in Malay, especially in everyday speech.

Not exactly.

Malay does not use a general verb like English am / is / are in the same way. Very often, Malay simply puts the subject and the description/location together.

For example:

• Dia guru. = He/She is a teacher.
• Buku itu di meja. = The book is on the table.

So in Malay, a sentence does not always need an equivalent of is/are.

Here, berada adds the sense of being located somewhere, but it is not a universal translation of to be in all contexts.

Because di here is a preposition, not a prefix.

• di luar = outside
• di rumah = at home
• di sekolah = at school

When di means in / at / on, it is written separately from the following word.

But when di- is a passive verb prefix, it is written attached:

• ditulis = written
• dibuka = opened
• dibaca = read

So:

• di luar = correct
• diluar = nonstandard in this meaning

Luar means outside, outer, or exterior, depending on context.

Examples:

• di luar = outside
• bahagian luar = the outside part / exterior
• luar negara = abroad / outside the country

In your sentence, di luar is the common phrase meaning outside.

Yes. That is perfectly possible and often more natural in everyday speech.

Compare:

• Geng itu berada di luar.
  Slightly more explicit, a bit more formal or written.

• Geng itu di luar.
  Shorter, very natural, conversational.

Both mean essentially the same thing in most contexts.

It can feel like either one, depending on context.

Literally, itu is that. But in real Malay usage, noun + itu often also helps mark something as specific or already known, which can overlap with English the.

So geng itu could be understood as:

• that group
• the group
• those people, depending on situation

English and Malay do not match perfectly here, so context matters.

A simple learner-friendly pronunciation guide would be:

• geng ≈ geng with the final ng as in sing
• itu ≈ ee-too
• berada ≈ buh-RAH-duh
• di ≈ dee
• luar ≈ loo-ar

A smoother full reading:

• geng ee-too buh-RAH-duh dee loo-ar

A few notes:

• Malay pronunciation is usually quite regular.
• The r in berada and luar is typically tapped or lightly rolled.
• Stress is usually not as strong or dramatic as in English.

Malay does not usually mark plural nouns the way English does.

So geng can already refer to a group as a single collective noun:

• geng itu = that gang / that group

Malay often relies on context rather than changing the noun form.

Sometimes Malay shows plurality by:

• context
• number words
• reduplication

For example:

• orang = person / people, depending on context
• buku-buku = books

But with a collective noun like geng, there is usually no need for extra plural marking.

Yes. In casual spoken Malay, you might hear:

• Geng itu kat luar.
• Geng tu kat luar.
• Diorang kat luar. if the speaker means they’re outside

Notes:

• kat is a casual spoken form of di for location.
• tu is a spoken short form of itu.
• diorang means they / those people in colloquial Malay.

So Geng itu berada di luar sounds correct and natural, but somewhat more careful or standard than the most casual spoken versions.
