I’m struggling with the etymology:
papa-…-poulos: son of pope …
hartofylaka(s): filer, where you keep documents, papers, mobile or not
missing the point of “ko”
Could be also:
papa-…-poulos: son of pope …
hartofyla(kas): filer, where you keep documents, papers, mobile or not
kako: bad
Son (poulos) of the bad (kako) files keeping (hartofyla[ka]) pope (papa)?
Tells a story
