@Goryvlad @Sviatogor

Svviatogor is correct G is not really a natural letter in Slovak it exists mainly in loan words or in dialect (kto being pronounced as gdo) ECT. Just as sviatogor already mentioned Czech Slovak Ukrainian and Belarusian had a shift from g>h I think around the 13 century. That’s why if u compare Slovak and Czech to Serbian and Croatian u have cognates like hlava and glava, pohľad and poglad, mnoho and mnogo. This is just a fact of linguistics.
