Numbers

1. Nol

   Zero (0)

   Grammar Note

   "Nol" comes from Dutch "nul" (ultimately Latin "nullus"). Used in phone numbers, prices, etc. In everyday speech, "kosong" (empty) is also used for 0 — e.g. reading phone numbers.

2. Satu

   One (1)

   Grammar Note

   Indonesian numbers: 11=sebelas, 12-19 = [digit] + belas. 20+ = [tens] + puluh + [digit]. 100=seratus, 1000=seribu. "Se-" prefix = one

3. Dua

   Two (2)

   Grammar Note

   "Dua" is the base for 20 (dua puluh), 200 (dua ratus), 2,000 (dua ribu). "Keduanya" (both of them) = ke- prefix + number + -nya suffix.

4. Tiga

   Three (3)

   Grammar Note

   From "tiga" we get "ketiga" (third), "bertiga" (as a group of three). "Ber- + number" means "together as a group of N" — berdua (as two), bertiga (as three).

5. Empat

   Four (4)

   Grammar Note

   "Empat" gives "keempat" (fourth), "berempat" (as four). Reduplication of numbers expresses "N at a time" — "dua-dua" (two by two), "satu-satu" (one by one).

6. Lima

   Five (5)

   Grammar Note

   "Lima" forms "kelima" (fifth), "berlima" (as five). Also: lima puluh (50), lima ratus (500), lima ribu (5,000). Very common for rupiah amounts.

7. Enam

   Six (6)

   Grammar Note

   "Enam" gives "keenam" (sixth). 16 = "enam belas" (6 + belas/teen), 60 = "enam puluh" (6 × 10). The Indonesian number system is highly regular.

8. Tujuh

   Seven (7)

   Grammar Note

   "Tujuh" → "ketujuh" (seventh). 17 = "tujuh belas", 70 = "tujuh puluh". "-belas" is equivalent to English "-teen" for 12–19 (11 = sebelas is irregular).

9. Delapan

   Eight (8)

   Grammar Note

   "Delapan" → "kedelapan" (eighth). 18 = "delapan belas", 80 = "delapan puluh". Numbers never change form — meaning is determined by word order.

10. Sembilan

    Nine (9)

    Grammar Note

    "Sembilan" → "kesembilan" (ninth). 19 = "sembilan belas", 90 = "sembilan puluh". "Sembilan ribu" (9,000 Rp) is a common amount in Indonesian daily life.

11. Sepuluh

    Ten (10)

    Grammar Note

    "Puluh" = tens. "Dua puluh" (20), "tiga puluh" (30). "Ribu" (thousand), "juta" (million) — essential for Indonesian rupiah prices

12. Seratus

    One hundred (100)

    Grammar Note

    "Se-" is the prefix form of "satu" (one). Seratus (100), seribu (1,000). Combines as "dua ratus" (200), "tiga ratus" (300) etc. Used for 100 Rp coins.

13. Seribu

    One thousand (1,000)

    Grammar Note

    "Ribu" (thousand) is the daily unit for rupiah: "dua ribu" (2,000 Rp), "sepuluh ribu" (10,000 Rp), "lima puluh ribu" (50,000 Rp). Essential for daily transactions.

14. Satu juta

    One million (1,000,000)

    Usage

    Indonesian Rupiah (IDR) uses large numbers — a meal may cost tens of thousands, hotels hundreds of thousands to millions. "Jutaan rupiah" (millions of rupiah) is an everyday unit

    Grammar Note

    "Juta" (million) is essential for travel costs. "Dua juta" (2 million), "setengah juta" (500,000 = half million). Hotels and flights are often in jutaan. "Miliar" = billion.

15. Umur saya dua puluh tujuh tahun

    I'm 27 years old

    Usage

    How to answer "Berapa umur Anda?" (how old are you?). "Saya berumur dua puluh tujuh tahun" means the same thing in a slightly more formal register

    Grammar Note

    Possession is "noun + possessor", so "umur saya" is "my age". "Dua puluh tujuh" is built from "dua" (2) + "puluh" (tens) + "tujuh" (7); ten is "sepuluh" and twenty is "dua puluh". No copula is used

16. Tahun ini umur saya dua puluh delapan tahun

    I turn 28 this year

    Usage

    Putting "Tahun ini" (this year) at the front is enough to mean "I turn … this year"; no verb for "become" is needed

    Grammar Note

    "Ini" (this) follows its noun, so "tahun ini" is "this year"; the same shape gives "minggu ini" (this week) and "bulan ini" (this month). Time expressions sit naturally at the front, and the age phrase (umur + possessor + number + tahun) is unchanged
