Jika dompet saya hilang lagi, saya akan terus pergi ke balai polis.

Jika means if.

It is correct and natural, but it sounds a bit more formal or written than kalau, which is very common in everyday speech.

For example:

• Jika dompet saya hilang lagi... = If my wallet gets lost again...
• Kalau dompet saya hilang lagi... = same meaning, but more conversational

So learners should know:

• jika = if, somewhat formal/neutral
• kalau = if, very common in speech

In Malay, possession is often shown by putting the possessor after the noun.

So:

• dompet = wallet
• saya = I / me / my (depending on context)

Together:

• dompet saya = my wallet

This is a very common pattern:

• rumah saya = my house
• kereta saya = my car
• buku saya = my book

So unlike English, Malay usually does not need a separate word placed before the noun like my.

Hilang means lost, missing, or to disappear.

In this sentence, dompet saya hilang means my wallet is lost or my wallet goes missing.

A useful thing to notice is that Malay often does not require a verb like is in places where English does:

• Dompet saya hilang = My wallet is lost

Depending on context, hilang can also describe something that disappeared:

• Kunci saya hilang. = My keys are missing.
• Dia hilang. = He/She disappeared.

Here, lagi means again.

So:

• hilang lagi = gets lost again / is lost again

Lagi is a very common word, but it can have slightly different uses depending on context. Most often, learners first meet it as:

• again
• more / additional in some expressions

In this sentence, the meaning is clearly again.

Akan is a future marker, so it helps show that something will happen.

Here:

• saya akan terus pergi... = I will go straight/immediately...

Malay often does not require a future marker if the time is already clear from context. So in many real conversations, people might simply say:

• Jika dompet saya hilang lagi, saya terus pergi ke balai polis.

That can still be understood as future because the if clause already sets up a future possibility.

So:

• akan = makes the future meaning more explicit
• not always absolutely required in everyday Malay

In this sentence, terus means something like:

• straightaway
• directly
• immediately

So:

• saya akan terus pergi ke balai polis = I will go straight to the police station / I will go there immediately

Terus often gives the idea of doing something without delay.

Examples:

• Dia terus balik. = He/She went straight home.
• Saya terus makan. = I immediately ate / I went straight to eating.

The preposition ke means to.

So:

• pergi = go
• ke = to
• balai polis = police station

Together:

• pergi ke balai polis = go to the police station

In standard Malay, ke is normally used before a destination:

• pergi ke sekolah = go to school
• pergi ke rumah kawan = go to a friend’s house

In casual speech, people sometimes shorten things, but learners should use ke here.

Balai polis means police station.

Word by word:

• balai = hall / station / public office building in some contexts
• polis = police

So balai polis is the normal Malay term for a police station.

Yes, Malay can sometimes leave out a subject if it is clear from context, but repeating saya is perfectly normal and often clearer.

This sentence says:

• Jika dompet saya hilang lagi, saya akan terus pergi ke balai polis.

The second saya makes the main clause very clear:

• If my wallet gets lost again, I will go straight to the police station.

You may hear shorter versions in conversation, but for learners and in careful Malay, repeating the subject is natural.

Yes, the overall structure is quite similar to English:

• Jika dompet saya hilang lagi = If my wallet gets lost again
• saya akan terus pergi ke balai polis = I will go straight to the police station

So the pattern is:

• If + condition, result

That makes this sentence quite approachable for English speakers.

A few differences are:

• possession comes after the noun: dompet saya
• there is no verb is in dompet saya hilang
• adverbs like terus can sit before the main verb phrase

Yes. Kalau would be very natural, especially in conversation.

For example:

• Kalau dompet saya hilang lagi, saya akan terus pergi ke balai polis.

This means the same thing.

A simple rule:

• jika = good, slightly more formal
• kalau = good, very common in speech

Yes, in natural English translation it could be understood that way, depending on context.

Malay does not always distinguish as sharply as English between:

• my wallet is lost
• I lose my wallet

So dompet saya hilang lagi most literally means:

• my wallet gets lost again
• my wallet goes missing again

But in good English, that may be translated more naturally as:

• If I lose my wallet again...

So the Malay focuses on the wallet becoming lost, while English might express it from the speaker’s point of view.

Yes, it is natural and grammatical.

It sounds a little careful or formal because of jika and akan, but it is completely good Malay.

A more everyday spoken version might be:

• Kalau dompet saya hilang lagi, saya terus pergi ke balai polis.

Both are correct. The original sentence is just a bit more explicit and polished.
