LingoflyVowels that shift: rik → rokiv, den → dnia
In Ukrainian a vowel inside the word can change when an ending is added. English has a faint echo of this: "sane", but "sanity". For example: “Мені тридцять років” (meni trydtsiat rokiv) — I am thirty years old (rik → rokiv). A rule from the Ukrainian course: worked out on examples, not memorized as a wording.
How it works
In Ukrainian a vowel inside the word can change when an ending is added. English has a faint echo of this: "sane", but "sanity".
The most common swap is between i and o. The short form has i: rik, a year. Add an ending and o comes back: rokiv, years. The same happens in kin, a horse, and konia.
The other pattern is a vowel that simply drops out. den is a day, but "have a good day" is harnoho dnia. The e is gone.
You do not need to memorize every pair. After a few words, your ear starts to expect the change.
Table
| short form | with an ending | what changes |
|---|---|---|
| rik — a year | rokiv — years | i becomes o |
| kin — a horse | konia | i becomes o |
| den — a day | dnia | e drops out |

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.
