Question Tags: bukan, kan, ya, and benar | Indonesian Grammar

Indonesian question tags do not agree with a subject, tense, or auxiliary. Instead, bukan?, kan?, ya?, and benar? negotiate how much of a proposition the speakers already share and how strongly confirmation is requested. Kamu datang, kan? assumes or hopes that arrival is already common ground; Ini milikmu, bukan? asks for explicit confirmation; Besok, ya? gently checks or secures agreement.

English changes isn't it, don't you, won't they, and many other tags according to grammar. Indonesian can use the same kan? after a verbal, adjectival, nominal, or locative predicate. The difficult choice is social stance, not agreement morphology.

The core comparison

Tag	Typical stance	Broad register
kan?	speaker expects confirmation or invokes shared knowledge	informal conversation
ya?	soft check, reminder, or request for alignment	conversation; can be polite
bukan?	explicit confirmation of the proposition	neutral to careful
benar?	check that information is factually accurate	careful or formal

Kamu datang, kan?

You're coming, right? (informal confirmation)

Ini milikmu, bukan?

This is yours, isn't it?

Besok, ya?

Tomorrow, okay? (informal gentle check)

Rapatnya dimulai pukul sembilan, benar?

The meeting begins at nine, correct? (careful)

All four follow the proposition or focused fragment. In writing, a comma normally separates the tag and the direct question ends with ?.

Kan?: expected confirmation and shared knowledge

Clause-final kan? is especially common when the speaker believes the addressee can confirm the proposition, has mentioned it before, or is expected to agree (informal).

Kita pernah bertemu di kantor lama, kan?

We've met at the old office before, right? (informal)

Kamu sudah mengirim alamatnya, kan?

You've sent the address, right? (informal)

Jalan ini lebih cepat, kan?

This road is faster, right? (informal)

Pak Dodi masih di dalam, kan?

Mr. Dodi is still inside, right? (informal)

Dia ketua kelompok yang baru, kan?

He/She is the new group leader, right? (informal)

The tag does not change with kita, kamu, Pak Dodi, or dia, nor with verb, adjective, location, or noun identity. That is the central contrast with English auxiliary tags.

Because kan? presumes shared ground, it can sound impatient or pressuring when the proposition is disputed.

Kamu akan membantu saya, kan?

You'll help me, right? (informal; expects agreement)

This may be friendly reassurance among close peers or undue pressure in another relationship. Politeness cannot be read from the tag alone.

💡

Use kan? when “as we both know/expect” could precede the proposition. If the information is genuinely open, ask a neutral yes-no question instead.

Ya?: a softer check or request for alignment

Final ya? often softens a reminder, arrangement, or small request (informal). It seeks acceptance rather than testing a complex fact.

Kita bertemu di depan stasiun, ya?

Let's meet in front of the station, okay? (informal)

Tolong kirim fotonya sore ini, ya?

Please send the photo this afternoon, okay? (informal polite request)

Kamu tunggu di sini sebentar, ya?

Wait here for a moment, okay? (informal)

Nama lengkapnya ditulis di bagian atas, ya?

The full name goes at the top, okay? (informal instruction/check)

Kita bahas sisanya besok, ya?

Let's discuss the rest tomorrow, okay? (informal)

Ya? can make wording warmer, but it does not automatically make a command respectful. Pronouns, titles, tone, and the size of the imposition remain important.

Bukan?: explicit proposition checking

As a tag, bukan? asks the listener to confirm that the preceding proposition is correct. It can follow any predicate type, not only a noun, because it rejects the possibility that the whole proposition is wrong.

Anda pernah bekerja di Surabaya, bukan?

You have worked in Surabaya before, haven't you? (careful)

Gedung itu dibangun sebelum kemerdekaan, bukan?

That building was constructed before independence, wasn't it?

Ruang rapatnya di lantai tiga, bukan?

The meeting room is on the third floor, isn't it?

Warna ini terlalu gelap untuk ruang kecil, bukan?

This color is too dark for a small room, isn't it?

Yang menelepon tadi Bu Rina, bukan?

The person who called earlier was Ms. Rina, wasn't it?

Compared with casual kan?, full bukan? can sound more deliberate or careful. It is not mechanically selected because the main predicate is nominal.

Benar?: checking factual accuracy

Final benar? means “correct/is that true?” It explicitly presents the proposition as information to verify and fits interviews, hearings, instructions, and careful conversation.

Anda menerima surat tersebut pada tanggal lima, benar?

You received that letter on the fifth, correct? (formal)

Peserta yang hadir berjumlah empat puluh dua orang, benar?

There are forty-two participants present, correct? (formal)

Data ini berasal dari laporan tahun lalu, benar?

These data come from last year's report, correct? (formal)

Tidak ada biaya tambahan setelah pembayaran ini, benar?

There is no additional charge after this payment, correct? (careful)

The related fronted question Benarkah + clause? attaches -kah and can sound formal or emphatic.

Benarkah layanan itu akan dihentikan bulan depan?

Is it true that the service will be discontinued next month? (formal)

Write benarkah solid, but final tag benar? remains a separate word.

One proposition, four stances

Consider the proposition that a report has already been sent.

Laporannya sudah dikirim, kan?

The report has been sent, right? (informal; expected shared knowledge)

Laporannya dikirim hari ini, ya?

The report will be sent today, okay? (informal arrangement)

Laporannya sudah dikirim, bukan?

The report has been sent, hasn't it? (explicit check)

Laporannya sudah dikirim kemarin, benar?

The report was sent yesterday, correct? (factual verification)

The tags are not interchangeable decorations. Kan? leans on presumed common ground; ya? negotiates an arrangement; bukan? requests explicit confirmation; benar? checks accuracy.

Expected answers and negative propositions

For positive propositions, ya/benar + repeated predicate confirms. A rejection uses the negator appropriate to the correction—often tidak for a predicate or bukan for identity—plus the corrected proposition. Repetition avoids ambiguity.

A: Kamu ikut besok, kan? B: Ya, saya ikut.

A: You're joining tomorrow, right? B: Yes, I am.

A: Ini milikmu, bukan? B: Bukan, ini milik Sari.

A: This is yours, isn't it? B: No, it belongs to Sari.

A: Alamatnya sudah benar, ya? B: Ya, sudah benar.

A: The address is correct now, okay? B: Yes, it is correct.

With a negative proposition, bare ya/tidak can be interpreted through different conversational conventions. Repeat the decisive meaning.

A: Kamu tidak ikut besok, kan? B: Ya, saya tidak ikut.

A: You're not joining tomorrow, right? B: Correct, I'm not joining.

A: Kamu tidak ikut besok, kan? B: Tidak, saya tetap ikut.

A: You're not joining tomorrow, right? B: No, I am still joining.

The first confirms the negative proposition; the second rejects it. The full predicate is safer than a one-word answer. The negative-question guide develops this response problem.

💡

Answer the proposition, not the English tag. With negative tags, say the full positive or negative predicate so the listener never has to guess what ya or tidak confirms.

Politeness and power

A tag can turn information into a request for alignment. That is useful among peers but risky when the listener may feel unable to disagree. A neutral question or explicit request for confirmation can reduce presumption.

Anda menyetujui perubahan ini, kan?

You approve this change, right? (potentially pressuring)

Apakah Anda menyetujui perubahan ini?

Do you approve this change? (formal neutral question)

Mohon konfirmasi apakah jadwal tersebut sudah benar.

Please confirm whether that schedule is correct. (formal)

With a superior or unfamiliar person, bukan? and benar? may be more explicit than kan?, but titles and wording still matter. No tag is intrinsically polite in every context.

Spelling and the unrelated suffix -kan

Tag kan is a separate word after a comma. It is not the verbal suffix -kan, which attaches to a stem.

Kamu akan mengirimkan salinannya, kan?

You will send the copy, right? (informal)

Here mengirimkan contains suffix -kan, while the final kan? is the question tag. Do not write salinannyakan? or separate the suffix in mengirim kan.

Direct tags take a question mark. A softened directive can sometimes be punctuated as a statement in literary dialogue, but learners should use ? when the tag genuinely requests a response.

Common Mistakes

1. Copying English auxiliary agreement

❌ Kamu datang, tidakkah kamu?

Unnatural mechanical copy of English don't you for an everyday tag.

✅ Kamu datang sore ini, kan?

You're coming this afternoon, right? (informal)

2. Attaching the tag to the preceding word

❌ Rapatnya besokkan?

Incorrect spacing for the intended question tag.

✅ Rapatnya besok, kan?

The meeting is tomorrow, right? (informal)

3. Using kan for a genuinely open formal inquiry

❌ Anda memiliki izin kerja, kan?

Potentially leading in the intended neutral official interview.

✅ Apakah Anda memiliki izin kerja?

Do you have a work permit? (formal neutral inquiry)

4. Assuming ya always makes a command polite

❌ Serahkan semua uangmu sekarang, ya?

The tag does not make this coercive command polite.

✅ Tolong serahkan formulirnya kepada petugas, ya?

Please hand the form to the officer, okay? (informal polite request)

5. Giving a bare ambiguous answer to a negative tag

❌ A: Kamu belum makan, kan? B: Ya.

Potentially ambiguous — repeat whether you have eaten.

✅ A: Kamu belum makan, kan? B: Ya, saya belum makan.

A: You haven't eaten yet, right? B: Correct, I haven't eaten yet.

Key Takeaways

Indonesian tags do not agree with person, tense, or predicate type.
Kan? invokes expected shared knowledge, ya? gently seeks alignment, bukan? asks explicit confirmation, and benar? checks factual accuracy.
Tags appear clause-finally as separate words, usually after a comma and before ?.
Negative tag questions are safest when answered by repeating the full predicate.
Because tags seek agreement, choose a neutral question when the listener must be free to disagree.
