English uses not across many sentence types. Indonesian makes a more revealing choice: tidak normally negates verbal, adjectival, and prepositional predicates; bukan rejects a noun identity; belum means “not yet”; and jangan gives a negative command. Choosing the negator therefore tells the listener what kind of predicate follows and what temporal assumptions the speaker makes.
The four-way core choice
| Form | Core job | Basic example |
|---|---|---|
| tidak | deny an action, quality, state, or location | Dia tidak datang. |
| bukan | reject an identity or correct a noun phrase | Dia bukan dokter. |
| belum | say something has not happened or become true yet | Dia belum datang. |
| jangan | tell someone not to do something | Jangan datang. |
All four are separate words. They are not prefixes and do not fuse with the following predicate.
One proposition, four negative perspectives
Start with one event: Rina coming to today's meeting.
Rina datang ke rapat hari ini.
Rina is coming to today's meeting.
Now change what is being denied:
Rina tidak datang ke rapat hari ini.
Rina is not coming to today's meeting.
Yang datang ke rapat hari ini bukan Rina.
The person coming to today's meeting is not Rina.
Rina belum datang ke rapat hari ini.
Rina has not arrived at today's meeting yet.
Rina, jangan datang ke rapat hari ini.
Rina, do not come to today's meeting.
The first negative denies the action. The second corrects the identity of the person. The third says the arrival has not happened yet but remains expected or possible. The fourth addresses Rina with a prohibition. Indonesian cannot preserve all four meanings with one universal equivalent of English not.
tidak: actions, qualities, states, and locations
Put tidak before a verbal predicate.
Saya tidak minum kopi setelah pukul enam.
I do not drink coffee after six.
Mereka tidak bekerja pada hari Minggu.
They do not work on Sundays.
Bus itu tidak berhenti di halte ini.
That bus does not stop at this bus stop.
Indonesian adjectives can act as predicates without a word equivalent to English be. Negate these predicates with tidak too.
Kamar ini tidak besar, tetapi cukup nyaman.
This room is not large, but it is comfortable enough.
Makanan itu tidak terlalu pedas bagi saya.
That food is not too spicy for me.
Jalan itu tidak aman pada malam hari.
That road is not safe at night.
Location and other prepositional predicates also take tidak.
Pak Arif tidak di kantor pagi ini.
Mr. Arif is not at the office this morning.
Kunci cadangan tidak di dalam laci.
The spare key is not in the drawer.
The pattern is tidak + predicate, not an attached negative ending. For absence or nonexistence, use the fixed predicate tidak ada.
Tidak ada air panas di kamar mandi.
There is no hot water in the bathroom.
bukan: nouns, identity, and correction
Use bukan when the predicate identifies or classifies someone or something as a noun.
Saya bukan dokter; saya perawat.
I am not a doctor; I am a nurse.
Ini bukan tas saya.
This is not my bag.
Bangunan itu bukan sekolah lagi.
That building is no longer a school.
Mereka bukan anggota kelompok kami.
They are not members of our group.
Indonesian has no required copula corresponding to English am/is/are in these sentences. Bukan directly rejects the proposed identity.
Bukan also corrects one contrasted element, often with melainkan or tetapi: “not X, but Y.” This wider correction can include more than a simple noun, but it does not make bukan the ordinary negator for every verb.
Rapatnya bukan hari Senin, melainkan hari Selasa.
The meeting is not on Monday, but on Tuesday.
Saya datang bukan untuk mengeluh, tetapi untuk mencari solusi.
I came not to complain, but to look for a solution.
For a plain denial of datang, use tidak datang. In the last example, bukan specifically rejects one purpose and replaces it with another.
belum: not yet, with an open future
Belum says that a state or event has not become true up to the relevant time. It usually leaves open an expectation or possibility that it will happen later.
Kereta belum tiba di stasiun.
The train has not arrived at the station yet.
Saya belum makan hari ini.
I have not eaten yet today.
Laporan itu belum selesai.
That report is not finished yet.
Anak mereka belum bisa berjalan.
Their child cannot walk yet.
Compare tidak and belum:
Dina tidak membalas pesan saya.
Dina does not reply to my message.
Dina belum membalas pesan saya.
Dina has not replied to my message yet.
Tidak denies or reports nonoccurrence within the relevant frame and does not itself keep a later reply open. Belum views the reply as unrealized so far and normally keeps a later reply in view. This temporal expectation is built into the negator, not expressed by a verb tense.
jangan: negative commands and advice
Use jangan before the action or state you want someone to avoid. The subject is often omitted because the addressee is obvious.
Jangan membuka pintu sebelum saya kembali.
Do not open the door before I return.
Jangan terlalu dekat dengan tepi peron.
Do not stand too close to the platform edge.
Jangan khawatir; kami sudah menemukan alamatnya.
Do not worry; we have already found the address.
Anak-anak, jangan berlari di lorong.
Children, do not run in the corridor.
Tidak membuka pintu describes non-opening; jangan membuka pintu tells someone not to open it. English uses do not for both description and command in different structures, but Indonesian marks the command directly with jangan.
tak: a shorter marked alternative to tidak
Tak overlaps with tidak before many predicates. It is common in set expressions and can sound compact, literary, lyrical, or formal depending on context. Ordinary neutral conversation generally favors tidak.
Keputusan itu tak dapat diubah lagi.
That decision can no longer be changed. (formal)
Ia tak pernah melupakan kampung halamannya.
She never forgot her hometown. (literary)
Tak perlu menunggu saya; berangkatlah lebih dulu.
There is no need to wait for me; leave first.
Do not treat tak as an attached prefix: write tak dapat, tak pernah, and tak perlu separately.
tanpa: “without,” not a complete clause negator
Tanpa introduces something absent: a noun, an activity, or a larger phrase. It does not replace tidak as the main negative predicate.
Saya memesan teh tanpa gula.
I ordered tea without sugar.
Mira pergi tanpa membawa payung.
Mira left without taking an umbrella.
Kami menyelesaikan tugas itu tanpa bantuan tambahan.
We completed the task without additional help.
Dia masuk tanpa mengetuk pintu terlebih dahulu.
She entered without knocking first.
Write tanpa separately while preserving affixes inside its complement: tanpa membawa, not tanpamembawa or tanpa mem bawa. The dedicated tanpa page develops the layered scope and pragmatic effects that arise when this construction combines with other negatives.
nggak: everyday colloquial negation
Nggak is an extremely common conversational equivalent of tidak (informal). It belongs in speech, dialogue, texting, and casual writing, not in a formal report. Other colloquial spellings and regional distributions are covered separately.
Aku nggak tahu dia tinggal di mana.
I don't know where she lives. (informal)
Kita nggak jadi pergi malam ini.
We're not going after all tonight. (informal)
Menurutku, kopinya nggak terlalu pahit.
In my opinion, the coffee isn't too bitter. (informal)
Use tidak in formal correspondence:
Kami tidak dapat menghadiri rapat tersebut.
We are unable to attend that meeting. (formal)
This page writes colloquial nggak only inside explicitly informal examples. It never changes the standard spelling of surrounding affixed words.
Quick decision guide
- Is it a command telling someone not to act? Use jangan.
- Does “not yet” fit, with a possible later change? Use belum.
- Are you rejecting a noun identity or explicitly correcting X to Y? Use bukan.
- Otherwise, for a verb, adjective, state, or location, use tidak.
- Choose tak for its marked written/set-expression register, nggak for informal conversation, and tanpa for “without + complement.”
Common Mistakes
Using tidak before a noun identity
❌ Ayah saya tidak dokter.
Incorrect — dokter is a noun identity, so use bukan.
✅ Ayah saya bukan dokter.
My father is not a doctor.
Using bukan before an ordinary adjective
❌ Kamar hotel itu bukan bersih.
Incorrect — bersih is an adjectival predicate, so use tidak.
✅ Kamar hotel itu tidak bersih.
That hotel room is not clean.
Losing the “not yet” meaning
❌ Pesanan saya tidak tiba.
Wrong for the intended meaning ‘has not arrived yet’ — tidak simply denies arrival.
✅ Pesanan saya belum tiba.
My order has not arrived yet.
Using tidak for a prohibition
❌ Tidak menyentuh kabel itu!
Incorrect as a direct ordinary prohibition — use jangan.
✅ Jangan menyentuh kabel itu!
Do not touch that cable!
Treating tanpa as a finite negator
❌ Saya tanpa minum kopi pagi ini.
Incorrect as ‘I did not drink coffee’ — tanpa introduces an absent complement, not the main clause negation.
✅ Saya tidak minum kopi pagi ini.
I did not drink coffee this morning.
Key Takeaways
- Tidak negates verbal, adjectival, state, and location predicates; bukan rejects noun identity or creates explicit correction.
- Belum means “not yet” and keeps a later change open; jangan forms prohibitions.
- Tak is marked by register, nggak is informal, and tanpa means “without” before a complement.
- Negators remain separate words. Choosing one reveals both predicate category and the speaker's temporal assumptions.
