How Turkish Numbers Are Structured

The Turkish number system is extremely logical and consistently structured. Once you know the numbers from 1-10 and the tens, you've mastered almost the entire system.

1-10

Basic numbers: bir, iki, üç, dört, beş, altı, yedi, sekiz, dokuz, on

Regular basic numbers that must be memorized. They are the foundation for all other numbers.

11-19

Formation with "on-": on bir, on iki, on üç...

Simply on (ten) followed by the basic number. on bir (11), on iki (12) etc. Very regular.

20-99

Tens + basic number: yirmi bir, otuz iki, kırk üç

From 20 onwards, numbers are simply combined: tens digit + basic number. No connecting words like "and". Examples: yirmi bir (21), kırk beş (45).

100+

Hundred: yüz (100), yüz bir (101)

Yüz stands for 100, iki yüz for 200 etc. Numbers are simply appended: yüz bir (101).

Common Pitfalls When Learning Numbers

While the Turkish system is logical, there are a few things that can be unusual for English speakers:

  • No plural after numbers:
    After a number, the noun always stays singular. You say beş elma (five apple), not beş elmalar.
  • Similar-sounding tens:
    altmış (60) and yetmiş (70) can be easily confused. Careful listening is important here.
  • The number 1:
    bir means "one" but is also used as an indefinite article ("a/an"). bir ev can mean "a house" or "one house".
  • Numbers are written separately:
    Unlike compound words in English, numbers are written separately, e.g. yirmi beş (25), not yirmibeş.

Understanding and Using Numbers in Daily Life

In spoken Turkish, numbers are often pronounced quickly – especially when talking about:

  • Time:
    Saat bir = It's one o'clock
    Saat iki = It's two o'clock
    ikiyi çeyrek geçiyor = Quarter past two (2:15)
    iki buçuk = Half past two (2:30)
    üçe çeyrek var = Quarter to three (2:45)
    beşe on var = Ten to five (4:50)
    sekizi yirmi geçiyor = Twenty past eight (8:20)
  • Money amounts:
    on beş lira = 15 TL
    yirmi beş lira elli kuruş = 25.50 TL
    para = money (general)
    Bu kaç para? = How much does this cost?
  • Years:
    1453 → bin dört yüz elli üç
    1923 → bin dokuz yüz yirmi üç
    2024 → iki bin yirmi dört
  • Basic arithmetic:
    5 + 3 = 8 → beş artı üç eşittir sekiz
    10 - 4 = 6 → on eksi dört eşittir altı
    3 × 5 = 15 → üç çarpı beş eşittir on beş
    20 ÷ 4 = 5 → yirmi bölü dört eşittir beş
  • Fractions and decimals:
    ½ → yarım, buçuk
    ¼ → çeyrek
    0.5 → sıfır virgül beş
    3.14 → üç virgül on dört

Unique Characteristics of Turkish Numbers

Turkish has certain linguistic conventions and unique characteristics when dealing with numbers – here's an overview:

  • No plural after numbers:
    First things first: The noun after a number always stays singular. This means: üç araba (three car), not üç arabalar. This simplifies many things!
  • Number notation with period and comma:
    In Turkish, thousands are separated with periods, decimals with commas (opposite to US English):
    1.000,50 = bin virgül elli
  • Special words for fractions:
    For "half" there are two words: yarım (half an apple) and buçuk (two and a half). For "quarter" çeyrek is used.
