You will count from zero to twenty, build 11 to 19 from on and a unit, and use a number with a noun.

The idea

The numbers 0 to 10 are single words: sıfır, bir, iki, üç, dört, beş, altı, yedi, sekiz, dokuz, on. From 11 to 19 you say on first and then the unit, as two separate words: on bir, on üç, on dokuz. Twenty is a word of its own: yirmi.

Examples

  • Sınıfta on iki öğrenci var.There are twelve students in the classroom.After a number the noun stays singular: öğrenci, not öğrenciler.
  • Kapıda on beş kişi bekliyor.Fifteen people are waiting at the door.
  • Bugün hava sıfır derece.It is zero degrees today.
  • Saat on bir.It is eleven o’clock.Ten comes first: eleven is on bir, literally ten-one, and it is written as two words.
  • Dört kardeşim var.I have four siblings.Even with the possessive ending the noun stays singular after a number: dört kardeşim, not dört kardeşlerim.
  • on üçthirteenNot üç on and not onüç: the ten comes first and the two words stay apart.
  • on dokuznineteenNineteen is the last number built with on. Twenty has a word of its own.
  • yirmitwentyTwenty is not iki on: it has its own word, yirmi.
  • altısixThe word ends in the dotless ı. With a dotted i, alti, it would not be a Turkish word.

Watch out

Say the ten before the unit and keep the words apart: thirteen is on üç, not üç on and not onüç. Learners whose own language puts the unit first, as German and Arabic do, often reverse it. After a number the noun stays singular: on iki öğrenci, never on iki öğrenciler.

Try it yourself

  1. Write the number 13 in words.

    Show answer or example answer

    on üç

    on üç: the ten comes first and the unit second, and the two words are written apart: ten plus three.

  2. Write the number 6 in words.

    Show answer or example answer

    altı

    altı: the word ends in the dotless ı; alti with a dotted i is not a Turkish word.

  3. Eighteen children are playing in the garden. Write 18 in words.

    Show answer or example answer

    on sekiz

    on sekiz: ten plus eight; çocuk stays singular after the number, so there is no -lar.

  4. Write the number 4 in words.

    Show answer or example answer

    dört

    dört: the vowel is the rounded front ö and the word ends in t; dort would be a spelling mistake.
