Is there a resource to learn about what a "case" is?
We don't have these in English, so i have no idea what anyone is talking about when they throw around these terms.
There is a good summary at the website ukrainiangrammar.com:
Wow. That's confusing. I don't know how I'm going to remember all those cases!
The page you linked doesn't explain how to conjugate(?) nouns depending on their case. Is there somewhere to find the rules for this?
Hi Bryan, this other website is a good reference which goes into far more detail.
Try sections 6 and 7 and 16, for explanations about the cases. Click on the tabs to the right of the page.
