I've just found this site and goingback through the archives, I found the entry for 'dystopia', and I would like to clarify where it comes from. It derives from 'dys' and 'topos', 'bad' and 'place', not from 'dys' and 'utopia'. 'Utopia' itself is not a Greek word; the inside joke is that the transliterated 'u' prefix is used for both 'ou' - not - and 'eu' - good, so utopia means both good place and no place. The original Greek words are eutopos and outopos. To the modern ear, they sound virtually identical unless you are used to hearing such differences
Sir Thomas Moore probably intended the pun from the outset. He called it Utopia from (ou + topos) because it was a fictional place that did not exist, nor could it exist given human nature. It was "no place" on earth. But he was also no doubt fully aware people would take it to mean eu + topos, good place.
I would pronounce
eu the same as the English word 'you' or 'ewe' and
ou as in soup - there is quite an easily discernible difference. But that is only because that is how I was taught ancient Greek. No one knows of course with any certainty exactly how Homer or St Paul spoke. I think modern Greek would pronounce outopia as ootopia ('oo' as in zoo) and eutopia as 'eftopia' or something like that. How those diphthongs were pronounced in Moore's day I have no idea.
