Mii, tvii, svii, ikhnii: whose is it

The first three are well-behaved. Mii, tvii and svii decline like adjectives, with i in the masculine and o elsewhere: moya, moye, moi. For example: “Візьми свій ключ, не мій” — Take your own key, not mine. A rule from the Ukrainian course: worked out on examples, not memorized as a wording.

How it works

The first three are well-behaved. Mii, tvii and svii decline like adjectives, with i in the masculine and o elsewhere: moya, moye, moi.

Yoho and yii never change at all: yoho knyzhka, yoho knyzhky, z yoho knyzhkoiu. They are a frozen of form and refuse every ending. But ikhnii bends like any adjective: ikhnia khata, ikhnie avto, ikhni dity.

Svii works harder than English own. When the thing belongs to the doer, Ukrainian wants it: ia vziav svoiu valizu. Say moiu valizu instead and the suitcase sounds borrowed.

Two lookalikes live nearby: sam means by myself, on my own (ia zrobiv sam), while samyi means the very same (te same). One letter of difference, opposite jobs.

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.
