You will add -e/-a or -i to words that end in a vowel, put the linking y in the right place, and leave it out after consonants.

The idea

Turkish does not let two vowels meet where a word and a suffix join. When a word ends in a vowel and the suffix begins with one, a y goes between them: araba + a = arabaya, kapı + ı = kapıyı, Ayşe + e = Ayşe'ye. The y belongs to no suffix and does not change the harmony: the vowel after it still follows the last vowel of the word. After a consonant there is no y: okula, okulu. It also appears in hastayım and arabayla.

Watch out

Not every word that ends in a vowel takes y. The pronoun o takes n: ona, onu, never oya. A word with a possessive ending takes n too: arabası becomes arabasına. And the y cannot be dropped after a vowel: arabaa and kapıı do not exist.

Try it yourself

  1. Add the accusative: I am opening the door.

    Show answer or example answer

    kapıyı

    kapıyı: kapı ends in the vowel ı, so the accusative needs a y between the two vowels, and the back vowel gives -ı.

  2. Add the dative to kedi (cat): to the cat.

    Show answer or example answer

    kediye

    kediye: kedi ends in i, so a y separates it from the dative, and the front vowel i gives -e.

  3. Add the dative to okul (school): to school.

    Show answer or example answer

    okula

    okula: okul ends in the consonant l, so there is nothing to separate: no y, and the back vowel u gives -a.

  4. Add the dative to the name Ayşe: to Ayşe.

    Show answer or example answer

    Ayşe'ye

    Ayşe'ye: Ayşe ends in the vowel e, so the y comes after the apostrophe, and the front vowel e gives -e.

Write three sentences about things you give, open or look at. Use one vowel-ending word with -e/-a, one with -i and one consonant-ending word, and mark each y.
