Bahasa Indonesia memiliki perbedaan besar antara bahasa baku (formal/standard) dan bahasa sehari-hari (informal/colloquial). Memahami perbedaan ini sangat penting!
| Formal (Baku) | Informal (Sehari-hari) | Arti |
|---|---|---|
| saya | aku / gue | I/me |
| Anda | kamu / lo | you |
| Bapak (Pak) | — | Mr./Sir (also used as 'you' for men) |
| Ibu (Bu) | — | Mrs./Ma'am (also used as 'you' for women) |
| Formal | Informal | Arti |
|---|---|---|
| tidak | nggak / gak / enggak | no / not |
| apakah | (omitted / tone) | question marker |
| mengapa | kenapa | why |
| bagaimana | gimana | how |
| sudah | udah | already |
| belum | belom | not yet |
Dalam situasi formal, Bapak/Ibu digunakan sebagai kata ganti orang kedua ("you"):
"Pak mau minum apa?" = What would you like to drink, sir?
"Ibu dari mana?" = Where are you from, ma'am?

Practice ExercisesMixed formal and informal elements in the same utterance
Don't mix registers: 'Saya nggak mau' (saya=formal, nggak=informal) → choose 'Saya tidak mau' (formal) or 'Aku nggak mau' (informal).
Used Jakarta slang (gue/lo) in non-Jakarta or formal contexts
'Gue' (I) and 'lo' (you) are Jakarta slang, not standard informal Indonesian. Use 'aku/kamu' as the default informal pronouns.
Failed to use Bapak/Ibu as 'you' in formal situations
In formal Indonesian, address people as 'Pak' (men) or 'Bu' (women) instead of 'Anda' or 'kamu': 'Pak mau pesan apa?' (What would you like to order, sir?).
Selamat pagi, Ibu. Apa kabar?
Good morning, Ma'am. How are you?
Formal greeting. 'Ibu' (Bu) is used as a polite form of address for women — it's both 'mother' and 'ma'am'. Compare with Czech 'paní' or German 'Frau'.
Hei, apa kabar? Udah makan belom?
Hey, how are you? Have you eaten yet?
Informal greeting. 'Udah' = informal 'sudah' (already), 'belom' = informal 'belum' (not yet). 'Udah makan belom?' is an extremely common casual greeting in Indonesian!
Pak guru sedang mengajar di kelas.
The teacher (male) is teaching in the classroom.
'Pak' (short for Bapak) before a title or name shows respect. 'Pak guru' = male teacher (respected). 'Bu guru' = female teacher. This is standard in all registers.
Saya tidak mengerti. Bisa Bapak ulangi?
I don't understand. Could you repeat that, sir?
Formal register: 'saya' (not aku), 'tidak' (not nggak), 'Bapak' used as 'you' for a man. This is appropriate for speaking with teachers, officials, or strangers.
