Malay purpose expressions do more than translate English to or so that. The most useful question is who is expected to perform the intended action? If that actor is controlled by the main clause, untuk commonly introduces a compact verb phrase. If the intended action has its own overt actor, supaya or agar introduces a full proposition. These two linkers can also frame a desired outcome whose understood actor is the same as the main-clause actor. Demi presents a valued goal for which someone acts or sacrifices something.
This page concentrates on the architecture of purpose clauses, not on memorizing every conjunction or building basic sentences. Malay verbs do not change for person, so the linker's structure and the presence or absence of an explicit subject carry information that English often leaves to an infinitive.
The practical decision: one actor or two?
In a canonical untuk + verb phrase, the unexpressed actor of the second action is normally understood from the main clause. Linguists call this subject control: the subject of the main verb also controls the missing subject of the purpose phrase.
Kami datang awal untuk mendapatkan tempat duduk di hadapan.
We came early to get seats at the front.
The people who datang “came” are also the people who hope to mendapatkan “get” the seats. Malay does not repeat kami after untuk, just as English normally does not repeat we after to.
Farah membuka tingkap untuk membiarkan udara segar masuk.
Farah opened the window to let fresh air in.
Farah controls membiarkan, although udara segar is the actor of the still more deeply embedded verb masuk. The relevant comparison is between the main action and the action immediately following untuk.
When the purpose clause needs to name a different person who must carry out the intended action, use a finite-looking proposition with its own subject after supaya or agar. “Finite-looking” does not mean that the verb changes tense; it means that the clause can state its own actor, negation, and aspect.
Kami datang awal supaya anak-anak mendapat tempat duduk di hadapan.
We came early so that the children could get seats at the front.
Farah membuka tingkap agar udara segar dapat masuk.
Farah opened the window so that fresh air could come in.
Untuk: an action performed for a purpose
Untuk is neutral across conversation and writing. Before a verb, it presents the action as the means or objective of the main actor. Before a noun, it can instead mean “for” in the sense of recipient, allocation, or function; that noun use should not be mistaken for a clause.
Saya menyimpan resit itu untuk membuat tuntutan kemudian.
I am keeping the receipt to make a claim later.
Pasukan itu mengumpulkan data tambahan untuk menguji andaian tersebut.
The team collected additional data to test that assumption.
The second example is (academic). Both purpose phrases inherit their actor: saya will make the claim, and pasukan itu will test the assumption. English speakers sometimes insert an overt pronoun after untuk whenever English has “for someone to…”. Such clauses do occur, especially where untuk introduces a nominalized proposition, but they are easily ambiguous as purpose clauses. In careful production, use supaya or agar when the embedded actor genuinely changes.
Compare a recipient phrase with a purpose phrase:
| Structure | Example | Function |
|---|---|---|
| untuk + noun | Hadiah ini untuk ibu. | recipient: “This gift is for Mum.” |
| untuk + verb phrase | Saya membeli hadiah ini untuk menggembirakan ibu. | same-actor purpose: “I bought this gift to make Mum happy.” |
| supaya + proposition | Saya membeli buku itu supaya ibu dapat membacanya. | different-actor purpose: “I bought the book so Mum could read it.” |
Supaya and agar: a desired situation
Supaya introduces a situation the main actor wants to bring about. It is neutral and very common in speech and writing. Agar has essentially the same propositional structure but is more characteristic of (formal) instructions, speeches, administrative prose, and edited writing. Neither one makes the desired result a fact.

Sila matikan telefon agar mesyuarat dapat berjalan lancar.
Please switch off your phone so that the meeting can proceed smoothly.
Malay frequently places dapat, boleh, or tidak inside the purpose proposition. These words make possibility, permission, or negation explicit; they are not required merely because English uses can or could.
Kami menghantar peta lebih awal supaya tetamu tidak tersesat.
We sent the map earlier so that the guests would not get lost.
Dokumen itu disimpan dalam dua salinan agar maklumatnya tidak hilang.
The document is kept in two copies so that its information will not be lost.
The passive disimpan in the last example suppresses the person doing the storing because the preservation procedure matters more than the actor. The possessive clitic in maklumatnya is attached to its host; never write it as two words.
Demi: the goal worth acting for
Demi normally selects a goal noun or noun phrase: demi keselamatan “for the sake of safety”, demi keluarga “for the family’s sake”, demi masa depan negara “for the nation’s future”. It frames the goal as something valuable enough to justify effort, restraint, or sacrifice. That rhetorical force makes it common in (formal) speeches, campaigns, official notices, and solemn personal statements.
Demi keselamatan penumpang, perkhidmatan feri dihentikan sementara.
For the passengers’ safety, the ferry service was temporarily suspended.
Dia sanggup bekerja di luar daerah demi masa depan keluarganya.
He was willing to work outside the district for his family’s future.
In formal prose, demi can also precede a verbal goal such as demi memastikan keselamatan. The phrase still behaves conceptually like “for the sake of ensuring safety”, not like a neutral same-subject infinitive. Do not replace every untuk with demi: doing so makes ordinary intentions sound weighty or promotional.
Negative purpose: preventing an unwanted event
With a separate subject, put tidak after supaya/agar. With the same subject, untuk tidak + verb is possible, especially in careful writing, but Malaysians often choose a positive prevention verb such as mengelakkan “avoid/prevent” because it is clearer.
Saya memperlahankan suara supaya bayi itu tidak terjaga.
I lowered my voice so that the baby would not wake up.
Pihak sekolah mengubah jadual untuk mengelakkan pertindihan kelas.
The school changed the timetable to avoid classes overlapping.
The first plan has two actors: saya lowers the voice, while bayi itu must not wake. The second has institutional control: the school changes the schedule and thereby avoids the clash. Agar tidak is the more formal alternative to supaya tidak.
Purpose is not cause or result
Purpose looks forward from an intentional action; cause explains why an event occurred; result states what followed. The same two events can be framed differently, and the linker changes the claim.
| Relation | Malay | Claim |
|---|---|---|
| purpose | Dia berlari supaya tidak terlepas bas. | Not missing the bus was her intention. |
| cause | Dia berlari kerana sudah lewat. | Being late caused her to run. |
| result | Dia berlari sehingga tercungap-cungap. | Breathlessness actually resulted. |
Common Mistakes
1. Using untuk when the intended actor changes
❌ Saya menutup pintu untuk bayi itu tidak terjaga.
Incorrect for clear standard purpose marking — the baby, not I, is the actor of the second predicate.
✅ Saya menutup pintu supaya bayi itu tidak terjaga.
I closed the door so that the baby would not wake up.
2. Treating an intended result as an actual result
❌ Kami memasang tanda sehingga orang ramai tidak masuk.
Incorrect for the intended meaning — sehingga presents not entering as an actual result.
✅ Kami memasang tanda supaya orang ramai tidak masuk.
We put up a sign so that people would not enter.
3. Giving demi an ordinary neutral task
❌ Saya membuka aplikasi itu demi menyemak cuaca.
Unnatural in an ordinary context — demi makes checking the weather sound like a solemn cause.
✅ Saya membuka aplikasi itu untuk menyemak cuaca.
I opened the app to check the weather.
4. Separating the -nya clitic
❌ Kami menyimpan salinan supaya maklumat nya tidak hilang.
Incorrect — the clitic -nya must be attached to maklumat.
✅ Kami menyimpan salinan supaya maklumatnya tidak hilang.
We kept a copy so that its information would not be lost.
Key Takeaways
- Use untuk + verb phrase when the main actor controls the intended action.
- Use supaya (neutral) or agar (formal) for a desired proposition, especially with a different explicit actor.
- Use demi + goal noun phrase when the goal is presented as worth effort or sacrifice.
- Put tidak inside the purpose clause, and remember that purpose expresses intention rather than confirmed outcome.
