Belum means “not yet”: at a reference time, an expected event has not happened or an expected state has not been reached, but a later change remains possible. Rina belum datang does more than negate Rina's arrival—it places us before the arrival boundary we are waiting for.
This page develops that timeline and the aspectual uses of belum. The experiential guide explains the second element in belum pernah; broader negator choices, voice patterns, and individual verb meanings belong to adjacent pages.
The live-boundary timeline
The core timeline is:
| Before the boundary | Expected boundary | After the boundary |
|---|---|---|
| belum datang: arrival unrealized | Rina arrives | sudah datang: arrival realized |
| belum siap: readiness unrealized | becomes ready | sudah siap: readiness achieved |
| belum makan: meal unrealized | eats | sudah makan: meal completed |
Rina belum datang; kita tunggu lima menit lagi.
Rina has not arrived yet; let's wait five more minutes.
Kopinya belum siap, tetapi airnya sudah mendidih.
The coffee is not ready yet, but the water is already boiling.
Saya belum makan, jadi saya ikut ke kantin.
I have not eaten yet, so I will come to the cafeteria.
In each sentence, the second clause makes the live alternative visible: Rina may arrive, the coffee is being prepared, and the speaker intends to eat.
Place belum before the predicate
Belum is a separate word before a verb, an adjective-like predicate, an expected role expressed with menjadi, or a prepositional predicate.
Adik belum tidur karena masih membaca komik.
My younger sibling is not asleep yet because he/she is still reading a comic.
Laporan itu belum selesai; bagian kesimpulannya masih kosong.
The report is not finished yet; its conclusion section is still empty.
Dewi belum menjadi dokter; dia masih menjalani pendidikan profesi.
Dewi is not a doctor yet; she is still completing professional training.
Ayah belum di rumah karena keretanya terlambat.
Dad is not home yet because his train is delayed.
The predicate itself remains unchanged. Indonesian does not add a past participle, tense ending, or form of English have.
Berkasnya belum diperiksa oleh petugas.
The file has not yet been checked by an officer.
Passive di- remains attached to periksa, while belum remains separate: belum diperiksa. This page does not analyze the passive; the spelling simply shows the two boundaries.
Standalone belum answers a sudah question
In conversation, belum can stand alone when the missing predicate is obvious. A very common pair is sudah?—belum.
Sudah makan? Belum.
Have you eaten? Not yet.
Tugasnya sudah selesai? Belum, masih ada dua halaman.
Is the assignment finished? Not yet; there are still two pages.
Kereta dari Yogyakarta sudah tiba? Belum.
Has the train from Yogyakarta arrived? Not yet.
Belum is a complete aspectual answer because the question supplies the event and expected boundary. Answering tidak would simply reject the proposition and lose the “not yet” perspective.
Sudah siap berangkat? Belum, saya masih mencari kunci.
Are you ready to leave? Not yet; I am still looking for the keys.
Belum with sampai sekarang
Sampai sekarang “up to now” makes the current reference point explicit.
Dia belum datang sampai sekarang.
He/She still has not arrived.
Sampai sekarang, pihak hotel belum menjawab pesan kami.
So far, the hotel has not replied to our message.
Penyebab gangguan itu belum diketahui sampai sekarang.
The cause of the disruption is still not known. (formal)
The order can vary because sampai sekarang is a time adjunct, but belum still stands directly in the preverbal particle area. The event remains unrealized at “now”; later realization is not ruled out.
The reference time can be past or future
Belum is not a present tense. Context can place its reference point in the past or future.
Ketika saya tiba tadi malam, anak-anak belum tidur.
When I arrived last night, the children had not gone to sleep yet.
Pada saat rapat dimulai, direktur belum membaca laporan itu.
When the meeting began, the director had not yet read the report.
Besok pagi pukul enam, toko itu mungkin belum buka.
At six tomorrow morning, that shop may not be open yet.
Kalau kamu menelepon sekarang, mereka mungkin belum sampai di hotel.
If you call now, they may not have reached the hotel yet.
English switches among has not, had not, and will not have. Indonesian keeps belum and lets the time expression establish the reference point.
Belum pernah: no experience up to the boundary
Pernah asks whether an event belongs to someone's experience. Belum pernah says that no such experience exists up to the reference time, while a first experience remains possible later.
Saya belum pernah naik pesawat, tetapi bulan depan saya akan terbang ke Medan.
I have never flown before, but next month I will fly to Medan.
Lina belum pernah makan papeda; malam ini kami akan mengajaknya mencoba.
Lina has never eaten papeda; tonight we will invite her to try it.
Sampai saat itu, saya belum pernah memimpin rapat besar.
Up to that point, I had never led a large meeting.
Each timeline has a live later alternative:
| Reference point | Unrealized experience | Later alternative |
|---|---|---|
| now | has never flown | flight next month |
| before dinner | has never eaten papeda | first taste tonight |
| that past point | had never led a large meeting | the subsequent meeting may become the first |
Tidak pernah instead means “never/in no instance” and can state a settled habit: Saya tidak pernah minum kopi “I never drink coffee.” The dedicated negation pages develop that cross-category choice.
Belum with other time expressions
Time expressions can delimit the expected window or explain why it remains open.
Hari ini saya belum menerima paket apa pun.
I have not received any packages today.
Hingga batas waktu pendaftaran, kami belum mendapat konfirmasi.
By the registration deadline, we had not received confirmation.
Belum lama ini, jalan tersebut masih ditutup untuk umum.
Not long ago, that road was still closed to the public.
The fixed phrase belum lama ini means “not long ago/recently.” Here belum is part of a time expression, not directly marking ditutup.
Proyek itu belum akan dimulai sampai izin terbit.
The project will not begin until the permit is issued. (formal)
Belum akan sets a future expectation boundary: the start is not prospective until the required condition is met. This combination is useful but more advanced than basic belum + predicate.
Why tidak belum is wrong
Belum already contains negative meaning. Do not add tidak to make it negative. A sequence such as tidak belum datang does not produce English “has not yet arrived”; it stacks incompatible negators without a special contrastive structure.
❌ Rani tidak belum datang.
Incorrect—belum already means ‘not yet.’
✅ Rani belum datang, tetapi sudah mengirim pesan.
Rani has not arrived yet, but she has sent a message.
Common Mistakes
1. Using tidak for an expected event that remains open
❌ Pesanan saya tidak tiba, tetapi kurirnya masih dalam perjalanan.
Poor choice for the intended not-yet meaning—the courier's journey keeps arrival open.
✅ Pesanan saya belum tiba; kurirnya masih dalam perjalanan.
My order has not arrived yet; the courier is still on the way.
2. Adding tidak before belum
❌ Rombongan kami tidak belum siap berangkat.
Incorrect—do not add tidak to the already negative belum.
✅ Rombongan kami belum siap berangkat.
Our group is not ready to leave yet.
3. Putting belum after the predicate
❌ Mereka sampai belum di hotel.
Incorrect neutral order—belum precedes the predicate.
✅ Mereka belum sampai di hotel.
They have not reached the hotel yet.
4. Attaching belum to the verb
❌ Formulirnya belumdiisi oleh pemohon.
Incorrect spelling—belum is separate; passive di- stays attached to the verb.
✅ Formulirnya belum diisi oleh pemohon.
The form has not yet been filled in by the applicant.
5. Treating belum as a past-tense form
❌ Besok pukul enam, toko itu tidak buka, tetapi mungkin buka pukul tujuh.
Poor aspect choice for a future checkpoint—the expected later opening calls for belum.
✅ Besok pukul enam, toko itu mungkin belum buka.
At six tomorrow morning, the shop may not be open yet.
Key Takeaways
- Belum locates an unrealized event or state before an expected boundary; it is more than simple negation.
- It can stand alone in answers such as Sudah makan?—Belum.
- The reference point may be present, past, or future; Indonesian does not change the predicate form.
- Belum pernah means no experience up to the reference time while leaving a later first experience open.
- Write belum separately, keep verb affixes attached, and never add tidak merely to make belum negative.
