Medna
Medna (Serbian Cyrillic: Медна) is a settlement in the Mrkonjic Municipality of Republika Srpska entity in Bosnia and Herzegovina. Name 
There are two theories for the etymology of this settlement. The first is that the Ottomans named it Medina which is of Arabic origin for a Fortified Settlement. Older locals still refer to the place as Medina, the chance of this etymology is highly likely as there was a Castle named Prizrenac in the area before Ottoman arrival. The second theory is that the settlement derives from the Serbo-Croatian word Med (honey). Demographics
