Bil utiliti ada dalam perjanjian sewa.

Bil utiliti means utility bill or utility bills.

A useful thing to know is that Malay nouns usually do not change form for singular vs. plural. So:

• bil utiliti can mean a utility bill
• bil utiliti can also mean utility bills

You normally understand the number from context.

That is very normal in Malay.

Malay often leaves out things that English requires, such as:

• articles: a, an, the
• the verb to be in many simple sentences

So in English, you might expect something like:

• The utility bills are in the rental agreement

But in Malay, it is natural to say simply:

• Bil utiliti ada dalam perjanjian sewa.

Malay is often more compact than English in this way.

Literally, ada often means there is / there are / exists / is present, and dalam means in / inside.

So ada dalam literally means something like:

• is in
• is inside
• is contained in

In this sentence, it gives the idea that the utility bill(s) are in or part of the rental agreement.

However, if the intended meaning is specifically included in, Malay speakers would often prefer termasuk dalam instead of ada dalam.

Often, yes.

If you mean that utilities are included as part of the agreement, a more natural sentence is:

• Bil utiliti termasuk dalam perjanjian sewa.

Or, if you mean they are included in the rent itself:

• Bil utiliti sudah termasuk dalam sewa.

So:

• ada dalam = is in / appears in / is contained in
• termasuk dalam = is included in

The original sentence is understandable, but termasuk dalam is often more precise.

Perjanjian sewa means rental agreement or lease agreement.

It is made of:

• perjanjian = agreement
• sewa = rent / rental / lease / hire

So together:

• perjanjian sewa = an agreement for renting or leasing something

Depending on context, English could translate it as:

• rental agreement
• lease agreement
• tenancy agreement

The word order here is actually fairly straightforward for Malay:

• Bil utiliti = the topic / subject
• ada dalam perjanjian sewa = what is being said about it

So the structure is roughly:

• [noun phrase] + [predicate]

This is similar to English in a broad sense, but Malay often avoids extra function words. That makes it feel shorter and more direct.

You usually know from context.

Malay often does not mark plural explicitly. So bil utiliti can mean:

• the utility bill
• the utility bills

If a speaker wants to make plurality clearer, they might say:

• bil-bil utiliti = utility bills
• semua bil utiliti = all utility bills
• beberapa bil utiliti = several utility bills

In everyday Malay, simple repetition like bil-bil is possible, but speakers often rely on context or words like semua and beberapa instead.

Yes. Sewa has a broad meaning related to renting, hiring, or leasing.

Depending on context:

• sewa rumah = rent a house / house rental
• perjanjian sewa = rental agreement / lease agreement
• kereta sewa = rental car

So English may use different words, but Malay often uses sewa across all of them.

No. Bil is common in everyday use, especially for things like:

• bil elektrik = electricity bill
• bil air = water bill
• bil utiliti = utility bill

But Malay also uses other related words depending on context, such as:

• bayaran = payment
• caj = charge
• invois = invoice

So bil is a practical everyday word, but it is not the only possible choice.

Yes, that ambiguity is possible.

Because ada dalam literally means is in / is inside, the sentence could be understood as:

• the utility bills are mentioned in the rental agreement
• the utility bills are contained in the rental agreement

If you want to make it clear that the cost is included, then termasuk dalam is better:

• Bil utiliti termasuk dalam perjanjian sewa.

If you want to say they are specifically mentioned in the document, you could say:

• Bil utiliti dinyatakan dalam perjanjian sewa.
  = The utility bills are stated in the rental agreement.

A very natural way is:

• Bil utiliti sudah termasuk dalam sewa.

Other good options are:

• Utiliti sudah termasuk dalam sewa.
• Bil utiliti termasuk dalam bayaran sewa.

These are often more natural than ada dalam perjanjian sewa when talking about what the tenant pays.
