The strange lingo is called Nadsat and, it's not/never was a secret - it's based on Russian. This book is a massive cultural milestone, as is Kubrick's adaptation for the big screen. It's probably about 15 years since I read, and fell in love with, this book. Haven't actually gotten round to reading it again, but I bought several copies to give to friends, etc. You couldn't claim to be interested in popular culture and not have read this book - even if you don't enjoy it (and the violence is graphic), it's a must-read! I remember how strange the book felt, being written in this weird lingo which, at first, seems to alienate, but then, very quickly, has the effect of drawing you in to the world of Alex and his Droogs. At the time, Kubrick's film was still banned, and I waited several more years, until 1996/7, to see it (on a foreign satellite channel). Great film, better book.
