In reply to Iamgregp:
> Yeah I can read Greek letters too. It’s just that I don’t know what they mean.
They don't 'mean' anything, it's not some picture language like Ancient Egyptian or Chinese. The letters are phonetics like most modern languages which means some are a bit difficult to convert to languages with other pronunciations. I lived for years in Πόρτο Χέλι which has various translations, the X being a particular difficulty as it's pronounced as an H by a heavy smoker who forgot his false teeth and is clearing his throat at the same time. In Roman script it will be Porto Cheli or Porto Heli and has to do with eel fishing. The next city has at least 7 ways to write it's name. Greek road signs can be interesting, they write Bends (in English) as Bents as there is no D sound in Greek.
Ancient (classic) Greek is different to modern Greek thank goodness, at least the numbers work!
