Vowel harmony: the ending follows the word

Kazakh does what English spelling never dares: the whole word is pronounced in one mouth-shape, and the endings are not fixed — the last vowel of the word chooses the vowel inside the ending. 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 does what English spelling never dares: the whole word is pronounced in one mouth-shape, and the endings are not fixed — the last vowel of the word chooses the vowel inside the ending.

Vowels split into back (a, o, ū, y) and front (ä, ö, ü, i, e). Whatever the root has, the ending repeats: üy (front) → üyde (at home), but qala (back) → qalada (in the city).

If you have met Turkish, the machinery is identical to the last detail. If not: think of how an English -s whispers through "cats, dogs, boxes" — here the whole ending, not just one sound, changes its voice.

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.
