Language/Ukrainian/Grammar/Cases

In today's lesson, we will learn the purpose of Ukrainian cases and when to use them!

How to Use Ukrainian Cases

Cases are very important and not using them changes the meaning sometimes slightly:

• Я вчу українську - I learn Ukrainian
• Я вчу українською - I learn through Ukrainian (as in the lessons are in Ukrainian)

But sometimes it can make the meaning very different!

• Мама їсть курку. - Mom is eating the chicken.
• Маму їсть курка. - The chicken is eating mom.

Though I suppose, if you were saying the second one in a calm tone, they might cop on that your mother wasn't really being eaten by a chicken.

Here is the list of cases and there uses

• Nominative Case
• Genitive Case
• Dative Case*
• Accusative Case*
• Instrumental Case
• Locative Case
• Vocative Case
