In just a few weeks, I will be visiting Kiev. I intend to use Russian throughout my stay, as I do not know Ukrainian. There is one major issue, however--I realized that I do not know how to pluralize the Ukrainian currency. I am familiar with the pluralization rules for rubles (2-4=genitive singular, 5-20=genitive plural, etc.), but I am not sure if these apply to the гривня. I found out that the гривня is pluralized as гривні; is this regardless of how many (3 гривні vs. 10 гривні?) Since I will be speaking in Russian, should I change the ending to the Russian genitive singular, and Russian genitive plural, respectively?
