Indonesian often leaves subjects and objects unspoken when the participants already know who or what is meant. Sudah makan? can mean “Have you eaten?” and Sudah can answer “Yes, I have,” even though neither kamu nor saya appears. This is often called zero anaphora: a missing argument receives its reference from context.
The licensing source is shared attention, not verb agreement. Indonesian verbs do not carry person endings that identify “I” or “you.” Speakers omit an argument because it is active and recoverable in the conversation, situation, or text. This page introduces that discourse pattern while leaving demonstratives, full relative-clause syntax, and voice paradigms to dedicated adjacent pages.
For the inventory of forms that can remain explicit, first see the personal-pronoun overview. Bound forms such as -nya behave differently from a completely unspoken argument; their spelling and uses are treated on the object and possessive clitics page.
A dialogue with every reference expressed
Here is a complete exchange with an explicit subject, addressee, and object:
A: Kamu sudah membaca pesan dari Rina? B: Ya, saya sudah membaca pesan itu.
A: Have you read Rina's message? B: Yes, I have read that message.
Nothing is wrong with the dialogue, but repeating kamu, saya, and pesan itu can sound heavier than necessary once the situation is established.
The same exchange can be more compact:
A: Sudah membaca pesan dari Rina? B: Sudah.
A: Have you read Rina's message? B: Yes.
The question omits kamu; the answer omits saya and the entire predicate complement. The missing material remains understandable because only one relevant addressee and one message are under discussion.
Subject omission
A subject can disappear after it has been established or when the speech situation identifies it automatically.
Saya sudah sampai di kantor. Sekarang sedang menunggu di lobi.
I've arrived at the office. I'm waiting in the lobby now.
The second sentence omits saya. The first sentence establishes the speaker as topic, and no competing person intervenes.
A: Kamu jadi datang malam ini? B: Jadi. Mungkin tiba agak terlambat.
A: Are you coming tonight? B: Yes. I may arrive a little late.
The reply omits saya/aku because the respondent is obviously describing their own arrival. Repeating saya would be possible, especially for contrast—Saya jadi datang, tetapi Rina tidak “I am coming, but Rina isn't.”
Subject omission is especially common in imperatives because the addressee is built into the interaction:
Tolong tunggu di sini sebentar.
Please wait here for a moment.
Adding kamu could sound contrastive or unnecessarily direct. Indonesian can make a polite instruction without pronouncing “you.”
Object omission
An object can also be omitted once it is active in the discourse.
A: Laporannya sudah kamu kirim? B: Sudah saya kirim tadi pagi.
A: Have you sent the report? B: I sent it this morning.
The reply leaves out laporannya because the question has just named it. Compare the explicit version:
A: Laporannya sudah kamu kirim? B: Laporan itu sudah saya kirim tadi pagi.
A: Have you sent the report? B: I sent that report this morning.
The explicit object may be useful for contrast or correction, but it is not needed in a routine answer.
Kopinya sudah dingin, tetapi saya tetap minum.
The coffee was already cold, but I drank it anyway.
English requires it after drank. Indonesian can leave the object zero because kopinya is the only plausible drink under discussion. A clitic is also possible: saya tetap meminumnya. The choice between zero and -nya depends on how explicitly the speaker wants to keep the object in focus.
Paired comparison: saya and kamu present or absent
| Fully explicit | Context-supported omission | Effect |
|---|---|---|
| Kamu sudah makan? | Sudah makan? | “you” recovered from addressee |
| Saya sudah makan. | Sudah. | “I” and action recovered from question |
| Saya sudah membaca bukunya. | Sudah saya baca. | object recovered from prior topic |
| Kamu tolong tutup pintunya. | Tolong tutup pintunya. | imperative addressee omitted |
The explicit forms are not ungrammatical. They become useful under contrast, topic change, or potential ambiguity. The zero forms are natural only when the missing content is sufficiently accessible.
Diaries and personal notes
Diaries, schedules, and personal notes often maintain one implicit first-person subject across several clauses (informal).
Bangun pukul enam. Langsung mandi, sarapan, lalu berangkat ke stasiun.
Woke up at six. Showered right away, ate breakfast, then left for the station.
Writing saya before every verb would be correct but stylistically cumbersome. The diary frame fixes the experiencer as the writer. Headlines and compressed public writing may also omit predictable arguments, but their conventions belong to the register pages.
Instructions and recipes
Instructions omit the actor because the reader is understood as the person performing each step. They may also omit an object after first mention.
Cuci beras sampai bersih, lalu masukkan ke dalam panci.
Wash the rice until clean, then put it into the pot.
The second clause has no written subject and no repeated beras. Both are recoverable: the reader performs the action, and the washed rice is what goes into the pot.
Buka aplikasinya, pilih menu pembayaran, lalu tekan tombol konfirmasi.
Open the app, choose the payment menu, then press the confirmation button.
Repeated Anda would often make instructions heavier. Formal documents may state Anda once when defining the user, then rely on imperative structure (formal). Remember that Anda always begins with a capital when written.
Conversational zero anaphora
Everyday conversation builds common ground rapidly. Gesture, gaze, visible objects, and the immediately preceding turn can all supply reference.
A: Yang merah mau dicoba? B: Boleh, ambilkan yang ukuran sedang.
A: Would you like to try the red one? B: Sure, get me the medium-sized one.
The first speaker omits “you”; the second omits an explicit noun after yang merah has established the item class. Demonstrative and yang syntax are not developed here, but the example shows that shared visual attention can be as important as prior words.
When omission becomes ambiguous
Do not delete an argument before its referent has been established, or when several candidates compete.
Rina menelepon Sari setelah pulang dari kantor.
Rina called Sari after returning from the office. (Who returned is context-dependent.)
The understood subject of pulang could be Rina or Sari. If that distinction matters, repeat the name:
Setelah Rina pulang dari kantor, dia menelepon Sari.
After Rina returned from the office, she called Sari.
Likewise, isolated Sudah dikirim “already sent” is unhelpful if several documents are being discussed. Say Laporan bulanan sudah dikirim or attach a clear clitic where appropriate. Good omission depends on successful coordination, not on maximum brevity.
Orthography of expressed bound forms
If reference is expressed with ku-, kau-, -ku, -mu, or -nya, attach it: kubaca, kaubaca, bukuku, bukumu, bukunya. Do not use a space as though the clitic were an omitted full pronoun. Full Anda remains capitalized, and titles are capitalized only where EYD V prescribes. Ordinary Indonesian uses no mandatory accent marks.
Common Mistakes
1. Retaining every English pronoun
❌ Kamu tolong kamu buka pintu itu untuk saya.
Incorrectly repetitive — the addressee is already clear in the request.
✅ Tolong buka pintu itu untuk saya.
Please open that door for me.
2. Repeating an established object mechanically
❌ A: Sudah kirim laporannya? B: Saya sudah mengirimnya laporan itu.
Incorrect — the reply expresses the same direct object twice, with -nya and laporan itu.
✅ A: Sudah kirim laporannya? B: Sudah.
A: Have you sent the report? B: Yes.
3. Deleting a person before establishment
❌ Sudah menelepon tadi pagi.
Ambiguous without prior context — neither caller nor person called is established.
✅ Rina sudah menelepon saya tadi pagi.
Rina called me this morning.
4. Omitting amid two competing referents
❌ Rina bertemu Sari setelah selesai bekerja.
Ambiguous when the context must identify which person finished work.
✅ Rina bertemu Sari setelah Rina selesai bekerja.
Rina met Sari after Rina finished work.
5. Spacing an expressed clitic
❌ Laptop nya belum ku periksa.
Incorrect spelling — expressed bound forms attach to their hosts.
✅ Laptopnya belum kuperiksa.
I haven't checked the laptop yet.
Key Takeaways
- Indonesian can omit subjects and objects when shared attention makes them recoverable.

- Dialogues, diaries, instructions, and recipes commonly use zero anaphora.
- Keep an argument explicit for contrast, topic change, or ambiguity.
- When a clitic is expressed rather than omitted, attach it according to EYD V.
