Wilfried, maybe I'd have been more correct to say Middle English was a creole, from which Modern English (16th century onwards) developed as a fully-fledged languge. There is some discussion at this website: search for "creole", or scroll down till you find it; there's plenty more on the subject in there, if you have the leisure to find it.

I've noticed that when foreign films (movies) are dubbed into American English, all expletives, even fairly mild ones, are translated as "f*ck"!

I've always been intigued by the notion that many people use "I believe ..." to signify "it is my opinion that ..." giving a spurious weight of factuality to what may be nothing more than conjecture.

I had a friend who used to say "the difference between my opinion and yours is that my opinion is correct and yours isn't"! And it's true: if I think your opinion is correct, I'll start believing that instead; otherwise, I'll carry on believing myself.
