The noun before a ter- predicate is not assigned one fixed semantic role. It may denote a theme in a state, an animate undergoer in an accidental event, or something perceptible in an ability reading. What unifies these patterns is that this participant—not a controlling actor—is the clause's grammatical and informational center.
English translation can obscure that organization. In Tulisan itu terbaca, “that writing” is the Indonesian subject even though English may translate the clause as “people can read that writing.” To analyze an advanced example, combine three kinds of evidence: voice morphology, relativization, and the way the clause packages information.
Four valency frames, not one template
The neutral order is subject + particles + ter- predicate + complements or adjuncts. The predicate's lexical meaning determines how many participants it licenses.
| Frame | Model | Subject's role | Other participant |
|---|---|---|---|
| result state | Pintunya terbuka | theme in the resulting state | normally none |
| involuntary event | Saya terjatuh | undergoer | cause may be an adjunct |
| perceptibility | Tulisan itu terbaca | perceptible theme | reader is generic or optional |
| sensory result | Suaranya terdengar | audible theme | hearer is generic or optional |
Pintunya terbuka sedikit karena engselnya macet.
The door is slightly open because its hinge is stuck.
Saya terjatuh saat turun dari bus.
I fell while getting off the bus.
Tulisan itu terbaca jelas dari baris kedua.
That writing is clearly readable from the second row.
Suaranya terdengar sampai ke halaman belakang.
Her voice can be heard all the way in the backyard.
In the first clause, pintunya is not an object promoted from a necessarily recoverable opening event; the clause simply attributes an open state to it. In the second, saya is both grammatical subject and involuntary undergoer. In the last two, the writing and the voice occupy subject position, while the potential reader or hearer remains unexpressed.
Subject diagnostics
Position is useful but not decisive. A stronger diagnostic is subject relativization. Indonesian can directly relativize the subject with yang while leaving a gap in the relative clause. The four model participants pass this test naturally:
Pintu yang terbuka itu menuju ruang arsip.
The door that is open leads to the archive room.
Orang yang terjatuh tadi sudah dibawa ke klinik.
The person who fell earlier has been taken to the clinic.
Bagian tulisan yang terbaca hanya dua baris pertama.
The legible part of the writing is only the first two lines.
Suara yang terdengar dari dapur ternyata suara radio.
The sound heard from the kitchen turned out to be the radio.
Compare actor voice. In Mira membaca tulisan itu, Mira is the subject and tulisan itu is the object. A direct relative on the writing requires a voice change; tulisan yang Mira baca uses bare-verb object voice. By contrast, tulisan yang terbaca needs no further change because the perceptible theme is already the subject.
Mira membaca tulisan itu tanpa kesulitan.
Mira reads that writing without difficulty.
Itulah tulisan yang Mira baca tadi.
That is the writing that Mira read earlier. (informal)
Itulah tulisan yang masih terbaca setelah terkena air.
That is the writing that is still legible after getting wet.
The last two clauses do not mean the same thing. Mira baca retains a specific reader and event; terbaca evaluates the writing's legibility and leaves the reader generic.
Full nouns, pronouns, omission, and reordered information
Indonesian permits arguments recoverable from context to be omitted. It also freely places setting expressions first. Neither option changes the underlying subject of a complete clause.
Result state: Pintunya terbuka
Pintu belakang terbuka sejak subuh.
The back door has been open since dawn.
Pintunya masih terbuka.
It is still open.
Ternyata masih terbuka.
It turns out it is still open.
Sejak subuh, pintu belakang terbuka lebar.
Since dawn, the back door has been wide open.
The omitted subject in the third example is licensed by context. The time phrase in the fourth is fronted, but pintu belakang remains the subject.
Involuntary event: Saya terjatuh
Dian terjatuh di depan halte.
Dian fell in front of the bus stop.
Saya terjatuh ketika menghindari sepeda.
I fell while avoiding a bicycle.
Tadi terjatuh lagi, tetapi tidak terluka.
I fell again earlier, but I was not hurt. (informal; the subject is understood)
Di depan halte itulah Dian terjatuh.
It was right in front of the bus stop that Dian fell.
Subject omission in the third example is (informal) and depends on a salient speaker or third person. The locative-fronted fourth example focuses the scene; it does not turn halte into an argument of terjatuh.
Perceptibility: Tulisan itu terbaca
Tulisan pada amplop itu terbaca dengan jelas.
The writing on that envelope is clearly legible.
Tulisan pada kuitansi itu masih terbaca walaupun tintanya pudar.
The writing on that receipt is still legible even though the ink has faded.
Kalau dicetak lebih gelap, pasti terbaca.
If it is printed darker, it will definitely be legible.
Dari jarak dua meter, tulisan itu masih terbaca.
From two meters away, that writing is still legible.
Sensory result: Suaranya terdengar
Suara mesin itu terdengar dari kamar saya.
The sound of that machine can be heard from my room.
Suaranya terdengar semakin dekat.
Its sound seems to be getting closer.
Sekarang sudah tidak terdengar.
Now it can no longer be heard.
Dari lantai atas, suaranya terdengar sangat jelas.
From upstairs, its sound can be heard very clearly.
The suffix -nya in pintunya and suaranya is attached to its host. It can be possessive (“her voice”), definite (“the door”), or context-dependent (“its sound”); it is not a separate postverbal actor pronoun.
Expressing an actor, cause, or experiencer
A one-participant state such as Pintunya terbuka normally has no actor slot. If the opening action and its responsible actor matter, di- passive or meN- actor voice is the more transparent construction.
Petugas membuka pintu pada pukul delapan.
The attendant opened the door at eight.
Pintu dibuka petugas pada pukul delapan.
The door was opened by the attendant at eight.
Pada pukul delapan, pintunya sudah terbuka.
At eight, the door was already open.
Accidental transitive ter- predicates can license a suppressed actor. A full noun phrase may occur directly after the verb in everyday use, while oleh makes the actor relation explicit and is particularly useful with pronouns or in careful (formal) prose.
Tas saya terbawa Raka tanpa sengaja.
Raka took my bag along by accident. (informal)
Tas saya terbawa oleh Raka tanpa sengaja.
My bag was accidentally taken along by Raka.
Tas saya terbawa olehnya tanpa sengaja.
My bag was accidentally taken along by him.
Tas saya terbawa sampai ke Bogor.
My bag was accidentally taken all the way to Bogor.
Here tas saya is the affected subject. Raka or olehnya is the low-control actor, not a direct object. The clitic in olehnya attaches to oleh.
Causes are often expressed as adjuncts with karena, akibat, or a locative phrase rather than as actors.
Saya terjatuh karena lantainya licin.
I fell because the floor was slippery.
Kakinya terjepit di antara pintu dan kusen.
His foot got caught between the door and the frame.
For perceptibility predicates, an experiencer is optional because the construction often makes a generic claim. Oleh can identify an actual perceiver, while bagi gives the perspective from which something counts as readable or audible.
Tulisan kecil itu masih terbaca oleh para peserta di baris depan.
The small writing can still be read by the participants in the front row.
Bagi saya, tulisan pada layar itu masih terbaca.
For me, the writing on that screen is still legible.
Alarm itu terdengar oleh petugas jaga.
The alarm was heard by the duty officer.
Bagi saya, suaranya terdengar terlalu pelan.
To me, her voice sounds too quiet.
Lexical valency must still be learned
The prefix does not mechanically erase every complement. Some established ter- verbs have lexical argument frames. Teringat, for example, often takes an experiencer subject plus remembered content; tertarik selects an interest introduced by pada or terhadap.
Saya tiba-tiba teringat pesan Ibu.
I suddenly remembered Mom's message.
Mereka tertarik pada program pertukaran itu.
They are interested in that exchange program.
Laporan ini terdiri atas tiga bagian.
This report consists of three sections. (formal)
In Saya teringat pesan Ibu, English-speaking learners may call pesan Ibu an object, and some analyses do treat it as object-like. The practical point is narrower: this lexical frame cannot be predicted from accidental-passive terbawa or one-place stative terbuka. Learn the complement pattern with the word. The word-formation usage guide treats these lexicalized families in detail.
Alternations reveal participant roles
An actor-voice causative, a deliberate passive, and a low-control or resultant clause may describe related situations while assigning different roles.
Angin membuka pintu itu.
The wind opened that door.
Pintu itu dibuka oleh petugas.
That door was opened by the attendant.
Pintu itu terbuka karena tertiup angin.
That door came open because the wind blew on it.
Beni menjatuhkan gelas itu.
Beni dropped that glass.
Gelas itu terjatuh dari meja.
That glass fell off the table.
Beni terjatuh saat mengejar gelasnya.
Beni fell while chasing his glass.
The morphology distinguishes the frames: membuka and menjatuhkan foreground a causer; dibuka foregrounds an affected patient while retaining a deliberate event; terbuka and terjatuh foreground a resulting state or low-control undergoer. Word order alone would miss that contrast.
Common Mistakes
1. Treating the perceptible theme as a postverbal object
❌ Saya terbaca tulisan itu dari sini.
Incorrect for ‘I can read that writing from here’—this frame wrongly puts the reader before terbaca.
✅ Tulisan itu terbaca dari sini.
That writing is legible from here.
2. Adding an actor freely to a pure state
❌ Pintunya terbuka petugas pukul tujuh.
Incorrect for a deliberate opening by the attendant—terbuka presents the state, not that actor event.
✅ Pintunya dibuka petugas pukul tujuh.
The door was opened by the attendant at seven.
3. Using a bare pronoun as an accidental actor
❌ Tas saya terbawa dia sampai ke kantor.
Nonstandard in careful usage—the bare pronoun makes the actor relation unclear.
✅ Tas saya terbawa olehnya sampai ke kantor.
My bag was accidentally taken along by him to the office.
4. Detaching a clitic
❌ Suara nya tidak terdengar dari belakang.
Incorrect spelling—the clitic -nya attaches to suara.
✅ Dari kursi belakang, suaranya sama sekali tidak terdengar.
From the back seats, her voice cannot be heard at all.
5. Assigning roles from English translation alone
❌ Tulisan itu membaca dengan jelas.
Incorrect—tulisan cannot be the actor-subject of membaca in the intended ‘is legible’ meaning.
✅ Tulisan itu terbaca dengan jelas.
That writing is clearly legible.
Key Takeaways
- The preverbal noun may be a theme, undergoer, or perceptible entity; it need not be an actor.
- Relativization and voice morphology provide stronger role evidence than English translation or position alone.
- A ter- state usually lacks an actor, while an accidental event may express one with a full noun or oleh phrase.
- Argument omission and fronted settings change information structure without automatically changing grammatical roles.
- Lexicalized ter- predicates keep their own complement patterns, which must be learned individually.
