Hi, I had learned that the genitive plural for most nouns ends with -a, with a "movable a" added to a final consonant cluster. Djevojka -> djevojaka krletka -> krletaka However I've also seen djevojki and krletki (just to use these two examples). Is there a rule about when this alternative -i ending is used? Is it a Croatian vs Serbian thing? Hvala vam unaprijed.
