I have always called it Wih-vern but I know well that many people say Wye-vern. I believe your right tho in that it comes from Wye area which I pronounce like you. I would imagine that it could be treated as a local dialect difference. Perhaps northern Thrublanders pronounce it one way and Southern the other leading to much local mirth... Maybe we should have it as a West-East thing instead what with there being such a North-South dialect thing going on here in UK. Do you have such a difference in US ? I know of the Southern drawl like country music stuff and New Yorker and the Canadian difference which is so frequently poked at in Southpark but over here it is so vastly different over such short distances - 50 miles and your in whole new language. This is an area which has barely been acknowledged in fantasy. The Belgariad made references to localized customs a lot tho but even in that I don't remember the language or accents being highlighted.
