untuk: Beneficiary and Purpose | Indonesian Grammar

Untuk marks an intended endpoint: the person meant to benefit, the result someone aims to achieve, or the use for which something is designed. English often translates it as for or to, but English for also expresses duration and price—two meanings that Indonesian normally handles differently.

One prospective relationship

Beneficiary and purpose may look like separate dictionary meanings, but they share a perspective. Hadiah untuk Ibu points forward to the person meant to benefit; alat untuk membuka botol points forward to the action the tool is meant to enable. In both cases, untuk presents an intended outcome rather than a completed transfer.

Anak-anak menyiapkan hadiah untuk ibu mereka.

The children are preparing a gift for their mother.

Ini alat untuk membuka botol tanpa merusak tutupnya.

This is a tool for opening bottles without damaging their caps.

Kami belajar bersama untuk lulus ujian akhir.

We study together in order to pass the final exam.

💡

Think “intended for X.” X may be a beneficiary, an action, or a future result, but it is always viewed prospectively.

Beneficiaries

Before a noun or pronoun, untuk identifies who is meant to benefit from an object or action. It does not by itself say that the person has actually received anything.

Makanan di meja ini untuk para tamu.

The food on this table is for the guests.

Saya sudah menyediakan tempat duduk di depan untuk Anda.

I’ve saved a seat at the front for you.

Bisa tolong belikan obat ini untuk Nenek?

Could you please buy this medicine for Grandma?

This differs from kepada, which introduces the actual recipient of a directed transfer.

Saya membeli hadiah untuk Rina dan menyerahkannya kepada Budi untuk dibungkus.

I bought a gift for Rina and gave it to Budi to be wrapped.

Rina is the intended beneficiary, Budi is the recipient of the handover, and untuk dibungkus states the purpose of that handover. One sentence can therefore contain both prepositions without redundancy.

Purpose with an action

Untuk + verb phrase states what an action is intended to achieve. Indonesian verbs do not have infinitive forms, so the verb after untuk appears in its ordinary form. English usually uses to + infinitive or in order to.

Dia menabung setiap bulan untuk membeli rumah.

She saves every month to buy a house.

Saya menelepon untuk memastikan alamat pengirimannya.

I called to confirm the delivery address.

Kami datang lebih awal untuk membantu menyiapkan ruangan.

We came early to help prepare the room.

The understood subject of the purpose action is normally controlled by the main clause: dia is the one who will buy the house, saya confirms the address, and kami help. When the intended action has its own explicit subject, Indonesian often uses agar or supaya instead: Saya bicara pelan agar anak itu tidak terbangun “I spoke quietly so that the child would not wake up.” That broader clause structure belongs to purpose clauses.

Saya menutup pintu pelan-pelan agar bayi itu tidak terbangun.

I closed the door quietly so that the baby wouldn’t wake up.

Using untuk with an explicit subject is possible in some formal nominalized or evaluative structures, but learners should not treat it as a universal substitute for agar/supaya. The untuk complements page covers those more advanced patterns.

Intended use and suitability

Untuk links an object, place, time allocation, or product to its intended function. The main phrase does not have to name an active user.

Ruang kecil di lantai dua dipakai untuk rapat daring.

The small room on the second floor is used for online meetings.

Obat ini untuk sakit kepala ringan, bukan untuk migrain berat.

This medicine is for a mild headache, not a severe migraine.

Saya butuh tas yang cukup kuat untuk membawa laptop.

I need a bag strong enough to carry a laptop.

Ada waktu sepuluh menit untuk mengisi formulir ini.

There are ten minutes available to fill out this form.

The exact English label varies—for meetings, for a headache, to carry, in which to fill out—but Indonesian keeps the intended-use relation overt with untuk.

Complements and pronoun forms

Untuk can precede a noun phrase (untuk acara besok), an independent pronoun (untuk saya), or a verb phrase (untuk membuka). The short pronouns -ku and -mu may attach directly: untukku “for me,” untukmu “for you.” Untuknya is also possible, although untuk dia may be clearer when contrast is important.

Aku menyimpan potongan terakhir ini untukmu.

I saved this last piece for you. (informal)

Buku itu bukan untuk saya; sepertinya untuk dia.

That book isn’t for me; I think it’s for him/her.

The independent saya is neutral/polite, while aku and -ku belong chiefly to close, informal relationships (informal). The preposition itself is not informal. Its frequent conversational alternative buat is informal when it means “for”: Ini buat kamu “This is for you” (informal). See buat as a preposition.

Untuk is not every English “for”

Duration

Pure duration normally uses selama, not untuk.

Kami tinggal di Bali selama tiga hari.

We stayed in Bali for three days.

However, untuk tiga malam can be correct when the period is prospectively allocated, booked, or planned rather than merely measured.

Saya memesan kamar ini untuk tiga malam.

I booked this room for three nights.

This is a real semantic distinction, not a ban on untuk + time expression. Selama measures how long an event lasts; untuk assigns something to an intended period.

Price and exchange

English for can mark a purchase price or an exchanged item. Indonesian normally uses seharga “priced at,” dengan harga “at the price of,” or dengan “in exchange for/with.”

Saya membeli meja itu seharga lima ratus ribu rupiah.

I bought that table for five hundred thousand rupiah.

Dia menukar jadwal kerjanya dengan jadwal hari Jumat.

She exchanged her work shift for the Friday shift.

Untuk becomes possible only if the following phrase is genuinely an intended beneficiary or purpose, not simply because the English sentence contains for.

Spelling

Write untuk separately from a full noun or independent pronoun: untuk Ibu, untuk acara, untuk saya. Attach the clitics: untukku, untukmu, untuknya. This is not the same system as attached verbal prefixes such as di- in dibungkus.

💡

Before translating English for, classify its job: beneficiary/purpose → untuk; elapsed duration → selama; price → seharga/dengan harga; exchange → dengan.

Common Mistakes

1. Using untuk for elapsed duration

❌ Kami menunggu bus untuk dua jam.

Incorrect for pure elapsed duration — English for does not translate as untuk here.

✅ Kami menunggu bus selama dua jam.

We waited for the bus for two hours.

2. Using untuk for a purchase price

❌ Saya membeli sepatu ini untuk tiga ratus ribu rupiah.

Incorrect when the amount is the price rather than a purpose.

✅ Saya membeli sepatu ini seharga tiga ratus ribu rupiah.

I bought these shoes for three hundred thousand rupiah.

3. Doubling purpose markers

❌ Saya belajar untuk agar lulus ujian.

Incorrect — untuk and agar should not both introduce the same simple purpose.

✅ Saya belajar untuk lulus ujian.

I study in order to pass the exam.

4. Joining untuk to a full noun

❌ Hadiah ini untukIbu.

Incorrect — untuk is written separately before a full noun.

✅ Hadiah ini untuk Ibu.

This gift is for Mom.

5. Confusing intended beneficiary with actual recipient

❌ Saya menyerahkan paket itu untuk petugas loket.

Incorrect for the actual recipient — untuk makes the officer sound like the intended beneficiary.

✅ Saya menyerahkan paket itu kepada petugas loket.

I handed the parcel to the counter clerk.

Key Takeaways

Untuk links something to its intended beneficiary, purpose, result, or use.
Untuk + verb phrase usually has the same understood subject as the main clause; agar/supaya commonly introduces a different explicit subject.
Distinguish untuk from kepada: intended beneficiary versus actual recipient.
Do not translate every English for as untuk; duration, price, and exchange use other forms.
