How is the Old English name element 'Wyn' correctly pronounced?
Old English, or Anglo-Saxon, was a Germanic/Teutonic tongue,
related to other tongues like Frisian and other Scandinavian
languages. As such, the letter "w" would actually be pronounced as
a "v", and a "v" often pronounced as an "f". "F" was a lighter,
breathier version of the "f" we know today, a soft f, if you will.
"Y" was indeed pronounced like a short "i."
So in short, "-wyn" would be pronounced "-vin."
But in your LARP group, you can pronounce it however you want.
The letter written "w" in modern spelling of Old English represents
the letter wynn (ƿ), and the reason that letter existed is
precisely because it's <b>not</b> pronounced like "v"
(else they would have just used "v"!). The correct pronunciation is
in fact just like English "w". Anglo-Saxon "y" should be pronounced
like "u" in French "tu" or "lune".
