Bil elektrik menunjukkan deposit keselamatan dan tarikh bil.

Malay usually does not use articles like the, a, or an.

So:

• Bil elektrik can mean an electricity bill, the electricity bill, or just electricity bill
• The exact meaning depends on context

That is very normal in Malay. If needed, Malay can add words like itu to mean something closer to that/the, but it is not required here.

Menunjukkan means shows, indicates, or displays in this sentence.

It comes from the root tunjuk.

A useful distinction is:

• tunjuk = show / point / indicate
• menunjuk = to point
• menunjukkan = to show something, to indicate something

In this sentence, the verb has a direct object:

• deposit keselamatan
• tarikh bil

So menunjukkan is the natural form because the bill is showing those things.

The two instances of bil do different jobs:

• Bil elektrik = electricity bill
• tarikh bil = bill date / date of the bill

So the first bil is the main noun in electricity bill, while the second bil tells you what kind of date it is.

Malay often builds noun phrases this way:

• main noun first
• describing noun after it

So:

• bil elektrik = bill + electricity
• tarikh bil = date + bill

This is different from English word order in some cases.

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

So:

• bil elektrik = electricity bill
• literally: bill electric/electricity

This same pattern appears elsewhere in the sentence:

• deposit keselamatan = security deposit
• tarikh bil = bill date

So Malay often works like:

• head noun + modifier

whereas English often prefers:

• modifier + head noun

Literally, keselamatan often relates to safety or security, depending on context.

In billing or financial contexts, deposit keselamatan is best understood as:

• security deposit

So even if a learner first thinks keselamatan = safety, the more natural English translation here is usually security deposit.

Context matters a lot with words like this.

Not exactly in the same way as English adjectives work.

In bil elektrik, elektrik is functioning as a noun-like modifier after the main noun bil. Malay often uses nouns this way.

So although English says:

• electricity bill or electric bill

Malay says:

• bil elektrik

You do not need to force it into an English-style adjective category. It is more helpful to learn the pattern:

• main noun + describing word

Malay usually does not need a separate word like of for this kind of relationship.

So:

• tarikh bil = bill date / date of the bill
• literally: date bill

Malay often expresses possession or association just by putting two nouns together.

Other examples of this pattern are similar to:

• nama sekolah = school name / name of the school
• harga tiket = ticket price / price of the ticket

So tarikh bil is completely normal Malay structure.

Yes, it is a complete sentence.

It has:

• Subject: Bil elektrik
• Verb: menunjukkan
• Object(s): deposit keselamatan dan tarikh bil

So the structure is:

• [subject] + [verb] + [what is shown]

That makes it a normal, complete declarative sentence.

Yes, depending on context, menunjukkan could sometimes be translated more naturally as:

• shows
• displays
• indicates
• sometimes lists

If this is talking about what appears on a utility bill, English might naturally say:

• The electricity bill shows the security deposit and the bill date
• or The electricity bill lists the security deposit and the bill date

So shows is a direct translation, but lists may also fit the situation.

Usually, yes, if they mean a regular utility bill.

• bil is the common everyday word for bill
• invois is closer to invoice

For electricity, water, phone, and similar charges, bil is the most natural word in many everyday contexts:

• bil elektrik = electricity bill
• bil air = water bill
• bil telefon = phone bill

So bil elektrik sounds very normal.

Yes.

Malay often leaves things general unless it needs to be more specific. But you could say:

• Bil elektrik ini menunjukkan deposit keselamatan dan tarikh bil.
  = This electricity bill shows the security deposit and the bill date.

• Bil elektrik itu menunjukkan deposit keselamatan dan tarikh bil.
  = That/The electricity bill shows the security deposit and the bill date.

Without ini or itu, the sentence is still perfectly correct and natural. It is just less specific.
