Indonesian has 6 main question words: apa (what), siapa (who), di mana (where), kapan (when), mengapa / kenapa (why), bagaimana / gimana (how). For yes/no questions, simply raise your intonation at the end of the sentence — no auxiliary verb needed. Example: "Kamu mau makan?" (intonation up) = "Do you want to eat?"
Asking questions in Indonesian is dramatically simpler than English. There are no auxiliary verbs ("do", "does", "did") and no subject-verb inversion ("Are you...", "Will you..."). Indonesian relies on:
- Question words (W-questions) placed at the beginning, end, or in the natural noun position.
- Rising intonation for yes/no questions — same word order as a statement.
- The particle "kah" (formal) — turns a statement into a yes/no question.
The 6 W-question words
- Apa — what, also "is it / does it" for yes/no questions in formal speech
- Siapa — who
- Di mana / Ke mana / Dari mana — where (location / direction to / direction from)
- Kapan — when
- Mengapa (formal) / Kenapa (everyday) — why
- Bagaimana (formal) / Gimana (casual) — how
Plus the related "how much / how many" question words:
- Berapa — how much / how many (numbers, quantities, prices)
- Yang mana — which one
Word order — flexible
Question words typically go at the beginning of the sentence, but they can also appear in the natural position of the missing information:
- Apa kabar? = What news? (= How are you?) — beginning
- Kabar apa? = News what? — same meaning, less common order
- Siapa nama kamu? = What is your name? (lit. Who [is] name yours?)
- Nama kamu siapa? = same meaning — natural order
Yes/no questions — 3 ways
- Intonation only (most common in speech) — Kamu mau makan? ↗ = Do you want to eat?
- "Apa" at the start (slightly formal) — Apa kamu mau makan? = Do you want to eat?
- "-kah" particle (formal/written) — Maukah kamu makan? = Would you like to eat?
Negative questions and tag questions
- Kamu tidak mau? = Don't you want? (just intonation up)
- Kamu mau, kan? = You want, right? (the particle "kan" = "right?")
- Bukan begitu? = Isn't it so? (formal tag question)

How long have you been learning Indonesian?
Indonesian culture values indirectness and politeness. Asking direct questions to strangers — especially elders — without softeners can come across as abrupt. Here are 4 essential softening strategies:
1. Start with "Permisi" (Excuse me)
Permisi, di mana toilet? = "Excuse me, where is the toilet?"
Always use this when approaching a stranger. Solo question words feel curt.
2. Add the honorific (Pak, Bu, Mas, Mbak)
Permisi, Pak. Toilet di mana? = "Excuse me, sir. Where is the toilet?"
Honorifics are essentially required when speaking to anyone you don't know intimately.
3. Use "boleh" (may I) for requests
Boleh saya tanya? = "May I ask?" (a polite preamble before asking a delicate question)
Boleh minta tolong? = "May I ask for help?"
4. Avoid abrupt "Kenapa?"
Asking "Kenapa?" (why) at a stranger or elder can feel accusatory in Indonesian culture. Soften with: Maaf, boleh saya tanya kenapa... = "Sorry, may I ask why..."
The "have you eaten?" greeting
Sudah makan? ("Have you eaten?") is a classic Indonesian greeting, especially around meal times. It's not literal — the answer is usually a quick "Sudah" (Yes already) or "Belum" (Not yet) with no expectation of food being offered. Cultural equivalent of "How are you?" in English.
Question particles in chats
In WhatsApp / Instagram DMs, Indonesians often use:
- ? alone with rising intonation: "kamu di mana?" (where are you?)
- ya? at the end for friendliness: "udah makan, ya?" (you've eaten, yeah?)
- sih? for confused / surprised tone: "kenapa sih?" (why though?)
- dong? for cute insistence: "ke sini dong?" (come here, please?)
Do Indonesian questions need an auxiliary verb like "do" or "does"?+
No — there's no equivalent of "do" in Indonesian. The same word order as a statement is used; only intonation (rising) signals it's a question. "Kamu makan" = "You eat" / "Kamu makan?" (rising) = "Do you eat?".
What's the difference between "mengapa" and "kenapa"?+
Both mean "why". "Mengapa" is formal/written, used in newspapers and academic contexts. "Kenapa" is the everyday spoken version — what 99% of Indonesians use in daily conversation. Beginners should use "kenapa".
How do you ask "where" — di mana, ke mana, or dari mana?+
"Di mana" = where (location, "at where") — "Di mana toilet?" (Where's the toilet?). "Ke mana" = where to (destination) — "Mau ke mana?" (Where are you going?). "Dari mana" = where from (origin) — "Kamu dari mana?" (Where are you from?). Choose based on whether you're asking about being, going, or coming.
Is the "-kah" suffix used in everyday speech?+
Rarely. "-kah" is formal/written register, used in essays, official letters, formal speeches. In casual speech, Indonesians use intonation alone or the "apa" prefix instead. Foreigners should understand "-kah" but produce intonation-only questions in real conversation.
How do I ask "how much does it cost?" in Indonesian?+
"Berapa harganya?" (literally: how much its-price) is the standard. Casual: "Berapa?" alone works in markets and warungs. Add the item: "Berapa harga ini?" (How much for this?). "Berapa" handles all "how much/many" questions.
