Thank you!
You did it almost perfectly, with only one small problem: JSON really needs to quote every key and value with quotation marks.

One question though: is this dict for Russian or Belarussian?

It's for Belarussian. Because every belorussian understand russian, but on avarage not actually know belarussian language well.
