Vowel harmony: the ending follows the word

Kazakh endings are not fixed. The vowel inside an ending copies the last vowel of the word, so the whole word is spoken in one mouth shape. For example: “үй → үйде” — house → at home. A rule from the Kazakh course: worked out on examples, not memorized as a wording.

How it works

Kazakh endings are not fixed. The vowel inside an ending copies the last vowel of the word, so the whole word is spoken in one mouth shape.

Vowels come in two rows: back a, o, u, y, and front ä, ö, ü, i, e. Whatever row the root sits in, the ending joins it. House is üy, and at home is üyde. City is qala, and in the city is qalada.

One trap: look at the last vowel, not the first. In kitap the last vowel is a back one, so books comes out as kitaptar, never kitapter.

By example

  • үй → үйде
    house → at home
  • қала → қалада
    city → in the city
  • кітап → кітаптар
    book → books

How the rule settles in your head

A rule is not memorized from an explanation. It is memorized from an attempt to use it and a mistake — that is why the app delivers it mixed in with words, not as a separate lesson: it resurfaces exactly where you forgot it.
