Hello! I have been struggling with the moving accents in greek since I started. I've discovered some regularities: -ότητες in genetive case always becomes -οτήτων and -ματα -> -μάτων. But I can't tell why πόλεμος becomes πολέμου or αυτοκίνητο -> αυτοκινήτου. Are there more regularities and rules for the placement of accents? Does it depend on the number of syllables before or after the given accent? Or do you just have to learn them one by one? Cheers!
