Kacang itu ada di dalam beg.

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

So:

• kacang itu = that peanut / those peanuts / the peanut(s)

This is different from English, where we say that peanut with that before the noun.

A very common pattern in Malay is:

• noun + ini = this ...
• noun + itu = that ... / the ...

So kacang itu is completely normal Malay word order.

It can feel like either that or the, depending on context.

In many beginner sentences, itu often points to a specific thing already known in the conversation, so it can be understood as:

• that peanut / those peanuts
• or more naturally in English, sometimes just the peanut(s)

Malay does not use the in the same way English does, so itu often helps make a noun sound definite or identifiable.

Here, ada shows existence or presence, especially when talking about where something is.

So in Kacang itu ada di dalam beg, ada means something like:

• is located
• is there
• exists in

A natural English equivalent is:

• The peanut(s) are in the bag
• or There are peanut(s) in the bag, depending on context

In location sentences, ada is very common in Malay.

Not exactly. Malay does not use one general verb exactly like English to be in every situation.

Ada is often used for:

• existence: there is / there are
• presence: to be present
• location: to be at / in

So here it works because the sentence is about where the peanuts are.

But ada is not used in every kind of is/are sentence. For example, for simple identity or description, Malay often does not need any verb:

• Dia guru = He/She is a teacher
• Beg itu besar = The bag is big

So ada is specifically useful here because the sentence is about location.

Di dalam means inside or in.

It is made of:

• di = at/in/on (a preposition for location)
• dalam = interior, inside

Together, di dalam clearly means inside.

In everyday Malay, people very often just say:

• dalam beg = in the bag

So both of these are common:

• Kacang itu ada di dalam beg
• Kacang itu ada dalam beg

The version with di dalam sounds a little more explicit about being inside the bag.

Usually, the meaning is almost the same: in the bag.

• di dalam beg = explicitly inside the bag
• dalam beg = in the bag / inside the bag

In casual speech, dalam beg is extremely common and natural.
Di dalam beg can sound slightly more careful or more emphatic about the idea of being physically inside.

So for most beginner purposes, you can think of them as near-equivalents.

Good question. Here, di is a preposition, not a prefix, so it is written separately.

• di dalam beg = in the bag
• di rumah = at home
• di sekolah = at school

But there is also a different di-, which is a prefix used in passive verbs, and that one is written attached:

• ditulis = written
• dibuka = opened

So:

• di dalam → separate, because it is a preposition
• ditulis → attached, because it is a verb prefix

Yes. Beg is a common Malay word meaning bag, borrowed from English.

Malay uses many loanwords, and beg is one of them. Another common word you may also see is:

• tas = bag

So these are both possible in many contexts:

• di dalam beg
• di dalam tas

Usage can vary by region and speaker, but beg is perfectly normal.

It could be singular or plural. Malay nouns usually do not have to show number the way English nouns do.

So kacang can mean:

• a peanut / a bean / a nut
• peanuts / beans / nuts

The exact meaning depends on context.

If Malay speakers want to make plurality very clear, they can sometimes use reduplication:

• kacang-kacang = peanuts / beans / nuts

But in many normal sentences, plain kacang is enough.

The structure is:

• Kacang itu = the peanuts / that peanut
• ada = is/are located
• di dalam beg = in the bag

So the pattern is basically:

• noun phrase + ada + location

This is a very useful pattern in Malay for saying where something is:

• Buku itu ada di atas meja = The book is on the table
• Ali ada di rumah = Ali is at home

Yes, you can.

• Kacang itu ada di dalam beg = The/that peanut(s) are in the bag
• Kacang ada di dalam beg = Peanuts are in the bag / There are peanuts in the bag, depending on context

Leaving out itu makes the noun less specifically identified. Adding itu makes it sound more definite or more like something already known.

Yes, but the focus changes.

• Kacang itu ada di dalam beg focuses on the peanuts and tells you where they are.
• Ada kacang di dalam beg means There are peanuts in the bag and focuses more on the existence of peanuts in the bag.

So both are grammatical, but they are used in slightly different situations.

A simple pronunciation guide is:

• kacang → kah-chang
• itu → ee-too
• ada → ah-dah
• di → dee
• dalam → dah-lam
• beg → roughly beg with a short e, not bag

So the whole sentence sounds roughly like:

kah-chang ee-too ah-dah dee dah-lam beg

Exact pronunciation varies somewhat by speaker and region, but this is a good beginner approximation.
