The form buat has two grammatical lives. As a conversational preposition, it means “for” and overlaps strongly with untuk: Ini buat kamu “This is for you.” As a lexical root, it means “make” or “do” and appears in the standard verb membuat: Saya membuat kopi “I make coffee.” Context and sentence position distinguish the two.
This page focuses on that contrast in contemporary Indonesian. It leaves full subordinate-clause syntax and the complete derivational paradigm to dedicated pages such as the verb buat.
Prepositional buat: conversational “for”
Before a noun, pronoun, or action, buat can mark an intended beneficiary, use, or purpose. In this function it is especially natural in relaxed speech, personal messages, and casual online writing (informal).
Kue ini buat kamu; ambil saja.
This cake is for you; go ahead and take it. (informal)
Aku beli obat ini buat Ibu.
I bought this medicine for Mom. (informal)
Meja kecil itu buat menaruh printer.
That small table is for putting the printer on. (informal)
Like untuk, prepositional buat points toward an intended beneficiary or purpose. It does not mark an actual recipient in a completed transfer. Compare Aku beli hadiah buat Rina “I bought a gift for Rina” with Aku kasih hadiahnya kepada Rina “I gave the gift to Rina.” Rina is the intended beneficiary in the first clause and the actual recipient in the second.
Aku beli hadiah ini buat kamu, lalu paketnya kutitipkan kepada Dimas.
I bought this gift for you, then entrusted the package to Dimas. (informal)
Buat + action can express purpose in conversation:
Kami datang lebih awal buat bantu menyiapkan ruangan.
We came early to help prepare the room. (informal)
Uang ini buat bayar listrik bulan depan.
This money is for paying next month's electricity bill. (informal)
The bare verbs bantu and bayar suit this conversational register. In careful writing, use untuk membantu and untuk membayar. This is a coordinated register change, not merely a one-word substitution.
Buat and untuk overlap, but register selects
The same beneficiary or purpose can often be expressed with either word. Untuk is neutral and works in speech, formal reports, instructions, and academic prose. Prepositional buat brings a conversational tone.
Ini buat kamu.
This is for you. (informal)
Ini untuk Anda.
This is for you. (neutral/polite)
Dana tersebut digunakan untuk memperbaiki fasilitas umum.
The funds are used to repair public facilities. (formal)
An official report should not use conversational buat without a deliberate quoted or informal voice. Dana tersebut digunakan buat memperbaiki fasilitas umum is understandable, but its register clashes with dana tersebut digunakan. The formal version keeps untuk and the fully prefixed verb memperbaiki.
Not every English for takes either buat or untuk. Pure duration uses selama, price commonly uses seharga or dengan harga, and exchange can use dengan. The untuk page develops those distinctions.
Kami menunggu selama satu jam, bukan buat satu jam.
We waited for one hour, not 'for one hour' with buat.
Lexical buat: “make/do”
The root buat can itself express “make” or “do.” It appears bare in imperatives and in conversational predicates (informal). In careful active declarative clauses, membuat is the standard transitive verb.
Buat dua salinan sebelum rapat dimulai.
Make two copies before the meeting starts.
Aku buat kopi dulu, ya.
I'll make coffee first, okay? (informal)
Saya membuat dua salinan untuk setiap peserta.
I made two copies for each participant. (neutral/formal)
The active prefix is spelled correctly in membuat. The form is mem- + buat, not membbuat or menbuat. Other members of the lexical family include dibuat “made,” buatan “a product/made,” and pembuatan “making/production.” Their complete derivational behavior belongs on the affix pages.
Kursi itu dibuat oleh pengrajin lokal.
That chair was made by a local craftsperson.
Aplikasi buatan tim kami akan diuji minggu depan.
The application made by our team will be tested next week.
The root and preposition can occur in the same clause:
Aku buat teh hangat buat Ayah.
I'm making hot tea for Dad. (informal)
The first buat is the predicate “make”; it takes teh hangat as its object. The second is the preposition “for”; it introduces Ayah as beneficiary. English happens to use two different words, but Indonesian category and position do the disambiguation.
Casual and formal dialogue pairs
The following exchanges express closely matched content in different registers.
Beneficiary
A: Ini buat siapa? B: Buat Rina. Aku buat tadi pagi.
A: Who is this for? B: For Rina. I made it this morning. (informal)
A: Dokumen ini untuk siapa? B: Untuk Ibu Rina. Saya membuat salinan khusus untuk beliau.
A: Who is this document for? B: For Ms. Rina. I made a special copy for her. (formal/polite)
Purpose
A: Kamu ke kantor buat apa? B: Buat ambil laptop.
A: What are you going to the office for? B: To get my laptop. (informal)
A: Anda pergi ke kantor untuk keperluan apa? B: Untuk mengambil laptop saya.
A: For what purpose are you going to the office? B: To collect my laptop. (formal)
Buat apa? is an extremely common conversational question meaning “what for?” or “why?” (informal). The formal exchange uses untuk keperluan apa and a fully prefixed verb. Learners should not interpret the casual pair as defective Indonesian; it belongs to a different register.
Word boundaries and nearby forms
Prepositional buat is separate from a full complement: buat kamu, buat rapat, buat belajar. Bound pronouns attach in forms such as buatku and buatmu, but an independent pronoun stays separate.
Pesan singkat itu sangat berarti buatku.
That short message means a lot to me. (informal)
Do not confuse free prepositions with prefixes. Location di rumah and destination ke kantor are separate, while passive dibuat and derived kebutuhan contain attached di- and ke-. Follow EYD V word boundaries.
Hadiah itu dibuat di rumah lalu dibawa ke kantor.
The gift was made at home and then taken to the office.
Common Mistakes
Joining the preposition to a full complement
❌ Hadiah ini buatkamu.
Incorrect — buat is separate before the independent pronoun kamu.
✅ Hadiah ini buat kamu.
This gift is for you. (informal)
Building membuat with the wrong nasal form
❌ Saya menbuat laporan untuk rapat besok.
Incorrect affix form — meN- plus buat produces membuat.
✅ Saya membuat laporan untuk rapat besok.
I made a report for tomorrow's meeting.
Adding a preposition before the direct object of membuat
❌ Saya membuat untuk kue ulang tahun itu.
Incorrect — the thing made is the direct object of membuat.
✅ Saya membuat kue ulang tahun itu untuk Rina.
I made that birthday cake for Rina.
Doubling buat and untuk before one beneficiary
❌ Kue ini buat untuk kamu.
Incorrect — choose one beneficiary preposition.
✅ Kue ini untuk kamu.
This cake is for you.
