Object voice reorganizes a transitive event around its patient: Buku itu saya baca. The book is the initial subject or pivot in traditional descriptions, saya is the actor embedded before the bare verb, and baca retains the transitive relation between them. English translation reverses that packaging to “I read that book,” so English subject and object labels cannot simply be copied back onto the Indonesian word order.
This page diagnoses those argument roles through voice, relativization, omission, and valency. The overview introduces the form; discourse choice and particle scope belong to the next pages.
The core argument map
Compare the three principal voices for a reading event.
| Voice | Clause | Privileged argument | Actor expression |
|---|---|---|---|
| actor voice | Saya membaca buku itu. | saya, actor subject | initial subject |
| di- passive | Buku itu dibaca Rina. | buku itu, patient subject | postverbal third-person agent |
| object voice | Buku itu saya baca. | buku itu, patient pivot | preverbal pronoun |
Saya membaca buku itu di kereta.
I read that book on the train. (actor voice)
Buku itu dibaca Rina di kereta.
Rina read that book on the train. (di- passive)
Buku itu saya baca di kereta.
I read that book on the train. (object voice)
Each clause contains a reader and a book, but the examples deliberately use the actor type that each patient-oriented construction most naturally favors. The semantic actor is the reader in every case; its grammatical status follows the voice construction rather than real-world agency.
Patient-pivot diagnostics
Initial position and discourse continuity
The patient normally precedes particles, the actor, and the verb. It can remain understood across a coordinated patient-oriented chain.
Buku itu saya baca, saya beri catatan, lalu saya kembalikan ke rak.
I read that book, annotate it, then return it to the shelf.
Surat ini akan kami periksa, kami tandatangani, lalu kami kirim besok.
We will check, sign, then send this letter tomorrow.
The repeated pronoun actors are natural when each verb forms its own object-voice unit. A more compact coordinated clause may omit repeated material if the result stays clear, but learners should first preserve the patient–actor–verb mapping.
Relativization
A head noun corresponding to the patient can be linked with yang + actor + bare verb.
Buku yang saya baca itu hadiah dari Rina.
The book that I read was a gift from Rina.
Surat yang kami kirim kemarin sudah diterima.
The letter that we sent yesterday has been received.
Orang yang kamu lihat di lobi adalah direktur baru.
The person you saw in the lobby is the new director.
Actor voice makes a different participant accessible:
Orang yang membaca buku tebal itu adalah Rina.
The person reading that thick book is Rina.
Buku yang saya membaca is not the ordinary Standard Indonesian object relative, because membaca privileges saya as actor subject while the relative head asks for a patient gap.
Question formation
Apa yang kamu lihat? has the same argument structure as Buku yang kamu lihat. The questioned phrase occupies the patient-pivot position.
Apa yang kamu lihat dari balkon?
What do you see from the balcony?
Siapa yang kamu temui setelah rapat?
Whom did you meet after the meeting?
Buku mana yang akan kamu baca lebih dulu?
Which book will you read first?
To ask about the actor, use actor voice: Siapa yang melihatmu? “Who saw you?”
Siapa yang melihatmu di stasiun?
Who saw you at the station?
The two siapa questions differ by role, and voice makes that difference visible.
The preverbal actor is a restricted position
Full first- and second-person pronouns are the clearest occupants: saya, aku, kami, kita, kamu, kalian, Anda. They stand immediately before the bare verb.
Buku itu sudah saya baca.
I have already read that book.
Surat ini akan kami kirim sore ini.
We will send this letter this afternoon.
Apa yang kamu lihat di layar?
What do you see on the screen?
Masalah ini perlu kita bahas sekarang.
We need to discuss this problem now.
Dokumen tersebut harus Anda simpan selama lima tahun.
You must retain that document for five years. (formal/polite)
Particles normally occur before the actor–verb unit: sudah saya baca, akan kami kirim, sedang kamu lihat. An ordinary noun actor instead favors di- passive after the verb.
Buku tebal itu dibaca Rina tadi malam.
Rina read that thick book last night.
Surat ini akan dikirim oleh panitia besok.
This letter will be sent by the committee tomorrow.
Third-person dia can occur before a root, especially in conversation, but this overlap does not erase the basic person-sensitive distribution.
Buku itu dia baca sampai selesai.
He/She read that book to the end. (conversation)
Full noun, pronoun, and omitted arguments
The following pairs show why omission and noun type must be interpreted inside a voice frame.
A full noun actor
Rina membaca buku sejarah itu di perpustakaan.
Rina reads that history book in the library.
Buku sejarah itu dibaca Rina di perpustakaan.
That history book is read by Rina in the library.
The full name is initial subject in actor voice but postverbal agent in di- passive. Object voice is not the neutral place for an ordinary full noun actor.
A pronoun actor
Kami akan mengirim surat ini besok.
We will send this letter tomorrow.
Surat ini akan kami kirim besok.
This letter, we will send tomorrow.
Here kami changes from actor subject to preverbal actor as the patient becomes pivot.
An omitted patient
Once the patient is established, an answer can omit it while retaining the object-voice predicate.
A: Buku itu bagaimana? B: Sudah saya baca sampai selesai.
A: What about that book? B: I have read it to the end.
A: Suratnya kapan dikirim? B: Akan kami kirim besok pagi.
A: When will the letter be sent? B: We will send it tomorrow morning.
The omitted patient remains understood. The answer is not suddenly actor voice merely because no noun phrase is pronounced before sudah or akan.
Changed word order
Kamu melihat apa di taman?
What did you see in the park? (actor voice; wh in situ)
Apa yang kamu lihat di taman?
What is it that you saw in the park? (object-oriented question)
Both questions are natural. The first retains actor-first order and leaves apa in the object position; the second makes the questioned patient the relative-like pivot.
The actor–verb unit and clitic attachment
Nothing normally intervenes between a full pronoun actor and its bare verb. Aspect, modality, and negation precede the unit; manner and time adjuncts follow it or frame the clause.
Novel itu belum saya baca karena baru tiba kemarin.
I have not read that novel yet because it arrived only yesterday.
Surat ini tidak akan kami kirim tanpa persetujuan ketua.
We will not send this letter without the chair's approval.
Apa yang sedang kamu lihat sekarang?
What are you looking at now?
Bound ku- and kau- are even tighter: they attach orthographically to the stem.
Novel pendek itu sudah kubaca dua kali minggu ini.
I have read that short novel twice this week. (written/compact)
Undangan itu belum kaukirim, bukan?
You haven't sent that invitation yet, have you? (written/compact)
Full aku and kamu remain separate. The spelling difference records a genuine clitic-versus-word distinction.
Valency decides which patient can lead
Object voice cannot promote any nearby noun phrase. The selected direct object of the active verb becomes the patient pivot.
Kami akan mengirim surat ini kepada direktur.
We will send this letter to the director.
Surat ini akan kami kirim kepada direktur.
We will send this letter to the director. (theme as pivot)
Here surat ini is the theme object; kepada direktur remains an oblique recipient.
The suffix -i can select the recipient as object:
Kami akan mengirimi direktur itu surat resmi.
We will send that director an official letter.
Direktur itu akan kami kirimi surat resmi.
We will send that director an official letter. (recipient as pivot)
Likewise, -kan and -i remain on the bare voice stem because they determine argument structure.
Cerita itu saya bacakan kepada anak-anak.
I read that story to the children.
Ruang ini akan kami lengkapi dengan kamera.
We will equip this room with cameras.
There is no productive operation that simply promotes kepada direktur while retaining the simple stem kirim. Valency comes before voice.
Control becomes clearer in object voice
With a volitional predicate, the preverbal actor is normally understood as the controller of the desired action.
Buku pinjaman itu ingin saya baca malam ini.
I want to read that borrowed book tonight.
Surat ini ingin kami kirim sebelum rapat.
We want to send this letter before the meeting.
Compare Buku pinjaman itu ingin dibaca Rina, where context must determine whether Rina wants to read it or the book's patient subject is personified as wanting to be read. Object voice makes the human controller explicit inside the predicate.
Buku pinjaman itu ingin dibaca Rina malam ini.
Rina wants to read that borrowed book tonight; the control relation can be structurally ambiguous.
When exact control matters, Buku itu ingin saya baca or actor-voice Saya ingin membaca buku itu is clearer.
Common Mistakes
Mapping the English subject onto Indonesian initial position
❌ Saya buku itu baca tadi malam.
Incorrect order—the patient leads object voice, and the actor stands directly before the verb.
✅ Buku sejarah itu saya baca tadi malam.
I read that history book last night.
Retaining actor morphology after the pronoun
❌ Surat resmi ini akan kami mengirim besok pagi.
Incorrect—object voice uses bare kirim after kami.
✅ Surat resmi ini akan kami kirim besok pagi.
We will send this official letter tomorrow morning.
Misidentifying the questioned role
❌ Apa yang melihat kamu dari jendela?
Incorrect for ‘What did you see?’—this makes apa the actor that sees you.
✅ Apa yang kamu lihat dari jendela kamar?
What did you see from the bedroom window?
Promoting an oblique without changing valency
❌ Direktur itu akan kami kirim surat ini.
Incorrect for the intended recipient-pivot reading with simple kirim.
✅ Direktur itu akan kami kirimi surat ini.
We will send that director this letter.
Putting the actor after the bare verb
❌ Buku itu belum baca saya.
Incorrect—the pronominal actor must immediately precede the bare verb.
✅ Buku itu belum saya baca.
I have not read that book yet.
Key Takeaways
- The initial patient is the object-voice subject or pivot; the preverbal pronoun is the semantic actor.
- Voice morphology, relative-clause accessibility, and discourse continuity diagnose roles more reliably than English translation.
- Particles precede the tight actor–verb unit, while bound ku- and kau- attach to the verb.
- A recoverable patient may be omitted, but its role remains part of the understood object-voice structure.
- Valency determines which participant can become pivot; derivational -kan and -i remain attached to the stem.
