Indonesian object voice places an identifiable patient first, then expresses a pronominal actor immediately before a verb without actor-voice meN-: Buku itu sudah saya baca. This is not an incomplete active or defective passive. It is a central patient-oriented construction in Indonesian's voice system, used in conversation, edited prose, relative clauses, and questions.
This page treats advanced constraints and register. The preceding overview, argument guide, choice page, and aspect page cover the basic system. Here the focus is extraction, the actor–verb unit, suffix retention, agentless-looking environments, and realistic distribution.
The core sequence is tightly organized
The reusable frame is:
patient/topic + aspect or modal + pronominal actor + bare verbal stem
Buku itu sudah saya baca sampai bab terakhir.
I have already read that book through the final chapter.
Surat ini akan kami kirim besok pagi.
We will send this letter tomorrow morning.
Apa yang kamu lihat dari jendela?
What do you see from the window?
The actor appears after particles such as sudah and akan, but directly before the verbal stem: sudah saya baca, akan kami kirim, kamu lihat. Actor-voice morphology is absent because the patient, not the actor, is the privileged starting point.
Relative clauses are a core environment
When a relative-clause head is the patient, object voice allows a pronominal actor to remain overt.
Buku yang saya baca di kereta membahas sejarah Jakarta.
The book I read on the train discusses the history of Jakarta.
Surat yang akan kami kirim masih menunggu tanda tangan direktur.
The letter we will send is still awaiting the director's signature.
Foto yang kamu lihat tadi diambil sepuluh tahun lalu.
The photograph you saw earlier was taken ten years ago.
Compare an actor relative:
Mahasiswa yang membaca artikel itu adalah ketua kelompok kami.
The student reading that article is our group leader.
In mahasiswa yang membaca artikel, the head noun is the reader, so actor voice appears. In buku yang saya baca, the head noun is the thing read, so the embedded clause uses object voice. English keeps read unchanged, but Indonesian aligns relative-clause voice with the extracted participant.
Third-person pronouns also occur:
Artikel yang ia tulis memenangkan penghargaan jurnalistik.
The article that he or she wrote won a journalism award. (formal)
Kunci yang mereka ambil ternyata milik ruang sebelah.
The key they took turned out to belong to the next room.
In careful prose, a full noun actor often favors a di- relative—buku yang dibaca Rina—while buku yang Rina baca is widespread in conversation (informal). Pronominal object voice has the widest cross-register distribution.
Wh-extraction follows the same alignment
The patient question word or questioned phrase appears at the left edge, while the actor precedes a bare verb.
Apa yang sedang Anda baca?
What are you reading? (formal)
Surat mana yang akan kita kirim lebih dahulu?
Which letter will we send first?
Siapa yang kamu lihat di depan kantor?
Who did you see in front of the office?
The last siapa is semantically animate but grammatically the seen patient. Animacy does not turn it into the actor.
An actor question instead retains actor voice:
Siapa yang melihat kejadian itu?
Who saw that incident?
The contrast siapa yang kamu lihat versus siapa yang melihat is an exceptionally useful diagnostic: the first asks for the patient of seeing, the second for the perceiver.
Extraction is not permission to erase any preposition
Object voice directly licenses the selected patient. An instrument, location, source, or oblique participant needs its own relation expressed.
Itulah pena yang saya pakai untuk menulis surat ini.
That is the pen I used to write this letter.
Inilah kantor tempat kami mengirim semua paket.
This is the office from which we send all the packages.
Dengan siapa kamu berbicara setelah rapat?
Who did you speak with after the meeting?
Pena yang saya tulis surat wrongly treats an instrument as the written object. Orang yang saya berbicara wrongly drops dengan from an oblique relation. Voice alignment does not cancel lexical government.
Longer dependencies preserve the object-voice requirement in the clause where the patient receives its role:
Buku yang saya kira sudah dia baca ternyata masih tersegel.
The book that I thought he had already read turned out to still be sealed.
Buku is interpreted as the patient of embedded dia baca, not of saya kira. This long-distance pattern is possible, but multiple clause boundaries raise processing difficulty; careful prose often chooses a clearer paraphrase.
Actor–verb adjacency and particle order
In canonical object voice, aspect, modality, and negation precede the actor; the actor then stands immediately before the verbal stem.
Buku itu belum saya baca.
I have not read that book yet.
Surat ini tidak akan kami kirim tanpa persetujuan Anda.
We will not send this letter without your approval. (formal)
Masalah itu harus kamu selesaikan hari ini.
You must resolve that problem today.
The suffix in selesaikan remains because the corresponding verb family is menyelesaikan, not simple menyelesai. “Bare verb” means absence of actor-voice meN-, not removal of every affix.
Ordinary adverbs do not freely break the actor–verb unit. Compare the standard placement:
Buku itu sudah saya baca dengan teliti.
I have already read that book carefully.
Surat ini akan segera kami kirim setelah ditandatangani.
We will send this letter immediately after it is signed. (formal)
Here segera precedes the actor as part of the preverbal field. Surat ini akan kami segera kirim occurs in some usage but is marked; edited Standard Indonesian strongly favors akan segera kami kirim.
Bound actor forms preserve attachment
First- and second-person singular actors can surface as attached ku- and kau- forms.
Buku itu sudah kubaca dua kali.
I have already read that book twice.
Surat ini akan kukirim setelah makan siang.
I will send this letter after lunch.
Apa yang kaulihat di balik pagar?
What do you see behind the fence?
Write kubaca, kukirim, and kaulihat solid. Their full-pronoun alternatives remain separate: saya baca, saya kirim, kamu lihat.
Buku itu sudah saya baca dua kali.
I have already read that book twice.
Apa yang kamu lihat di balik pagar?
What do you see behind the fence?
The attached forms are common in writing and careful speech; kau- may sound literary or intimate depending on context, while full kamu is usually clearer in neutral conversation.
Do not add a resumptive object clitic
The fronted patient already fills the selected object role, so neutral object voice does not repeat it with -nya.
Laporan audit itu sudah saya baca.
I have already read that audit report.
Surat tersebut akan kami kirim hari ini.
We will send that letter today. (formal)
Laporan itu sudah saya membacanya combines actor voice with an unnecessary object clitic. A true left-dislocation may resume a topic inside a separate actor-voice clause—Laporan itu, saya sudah membacanya—but the pause and internal membacanya show a different construction.
Laporan itu, saya sudah membacanya sampai selesai.
As for that report, I have read it to the end.
The comma is not cosmetic: it represents a topic outside the following clause.
Suffixes and lexical families remain intact
Removing meN- exposes the correct verbal stem, which may still contain -kan, -i, or lexical per-.
| Actor voice | Object voice | What remains |
|---|---|---|
| membaca buku | buku saya baca | simple base |
| mengirimkan surat | surat saya kirimkan | -kan |
| mendatangi rumah | rumah saya datangi | -i |
| memperbaiki mesin | mesin saya perbaiki | per-...-i family |
Surat ini akan kami kirimkan kepada semua cabang.
We will send this letter to all branches. (formal)
Rumah itu pernah kami datangi ketika masih kecil.
We once visited that house when we were children.
Mesin yang saya perbaiki kemarin kembali rusak.
The machine I repaired yesterday is broken again.
Lexical valency survives the voice change. Do not reduce selesaikan to selesai or perbaiki to baik merely because the verb is called “bare.”
Agentless-looking clauses are not automatically object voice
Object voice normally contains an overt or attached actor. If the patient is fronted but no actor is expressed, careful Indonesian generally uses di-.
Buku itu sudah dibaca.
That book has already been read.
Surat ini akan dikirim besok.
This letter will be sent tomorrow.
Forms such as Buku itu sudah baca may occur as compressed colloquial speech in limited varieties, but they are not the neutral agentless counterpart of Buku itu saya baca.
Commands can also contain a bare verb and omitted addressee, but their syntax is imperative rather than object voice:
Baca buku itu sebelum kelas dimulai.
Read that book before class begins.
Kirim surat ini sebelum pukul tiga.
Send this letter before three o'clock.
The understood actor is “you,” but there is no fronted patient followed by a preverbal actor.
Corpus-realistic register distribution
First- and second-person object voice is common in both everyday speech and formal writing, especially in relative clauses, promises, plans, and statements about completed work. Third-person ia/dia/mereka + bare verb is also established, with ia especially comfortable in edited narrative. A full noun actor before a bare verb is frequent in conversation but more variable in formal standards.
Dokumen yang kami periksa telah memenuhi semua persyaratan.
The documents we examined have met all requirements. (formal)
Keputusan itu ia ambil setelah berkonsultasi dengan tim hukum.
He or she made that decision after consulting the legal team. (formal)
Film itu Raka tonton semalam, katanya bagus.
Raka watched that film last night; he says it was good. (informal)
Film itu ditonton Raka semalam dan akan dibahas dalam rapat.
Raka watched that film last night, and it will be discussed at the meeting. (formal)
There is no honest claim that one variant has identical frequency everywhere. Speaker age, region, medium, actor type, and editorial norm all matter. The robust generalization is that pronominal object voice itself is central Standard Indonesian, not casual erosion.
Annotated formal paragraph
Buku itu sudah saya baca secara menyeluruh. Catatan yang saya buat akan saya serahkan kepada editor sore ini. Surat ini akan kami kirim setelah semua lampiran diperiksa, sedangkan pertanyaan yang Anda ajukan akan kami jawab secara terpisah.
I have read the book thoroughly. I will give the notes I made to the editor this afternoon. We will send this letter after all attachments are checked, while we will answer the question you asked separately. (formal)
- Buku itu ... saya baca keeps an established book as topic.
- Catatan yang saya buat uses object voice inside a patient relative.
- Akan saya serahkan and akan kami kirim/jawab place the modal before the actor–verb unit.
- Passive diperiksa is solid, while no location phrase with free di is present.
Colloquial exchange
A: Apa yang kamu lihat tadi? B: Aku lihat orang keluar dari gudang. Videonya sudah aku kirim ke kamu, tapi pesan yang kamu kirim belum aku baca.
A: What did you see earlier? B: I saw someone leave the storeroom. I've sent you the video, but I haven't read the message you sent. (informal)
Apa yang kamu lihat, videonya ... aku kirim, and pesan yang kamu kirim ... aku baca are object voice. Initial aku lihat orang is instead a common informal actor-oriented reduction; identical bare morphology can therefore belong to different constructions.
Common Mistakes
1. Retaining actor-voice morphology
❌ Buku sejarah itu sudah saya membaca.
Incorrect—the preverbal actor in object voice requires the stem baca, not membaca.
✅ Buku sejarah itu sudah saya baca.
I have already read that history book.
2. Putting aspect between actor and verb
❌ Surat ini kami akan kirim besok pagi.
Incorrect neutral object-voice order—akan precedes the actor–verb unit.
✅ Surat ini akan kami kirim sebelum makan siang.
We will send this letter before lunch.
3. Using actor voice after an extracted patient
❌ Apa yang kamu melihat dari jendela?
Incorrect—the extracted question word is the patient, so lihat is bare after kamu.
✅ Apa yang kamu lihat di ujung lorong?
What do you see at the end of the corridor?
4. Removing a lexical suffix together with meN-
❌ Masalah itu harus kamu selesai hari ini.
Incorrect—the established transitive stem is selesaikan.
✅ Masalah itu harus kamu selesaikan sebelum rapat.
You must resolve that problem before the meeting.
5. Treating an agentless bare clause as neutral object voice
❌ Surat ini akan kirim besok.
Incorrect in careful Standard Indonesian—there is neither an object-voice actor nor passive di-.
✅ Surat ini akan dikirim melalui pos besok.
This letter will be sent by post tomorrow.
Key Takeaways
- Object voice is patient/topic + particles + pronominal actor + verb without actor-voice meN-.
- Patient relatives and questions require matching voice: buku yang saya baca, apa yang kamu lihat.
- The actor and verb form a tight unit; aspect, modality, and ordinary adverbs normally precede that unit.
- “Bare” removes actor-voice morphology, not lexical suffixes: kami kirimkan, saya datangi, saya perbaiki.
- Pronominal object voice is standard across registers; full-noun and agentless-looking bare patterns require more careful register and constructional analysis.
