Thank you Grockle! Geest. My neighbour today said 'Gwist' but I like Geest better! Yes, Jon, I have heard Letheringsett pronounced as you suggest, but more like 'Lairnset'. There's been a movement fairly recently to attempt to over-ruralise Norfolk in rather a twee way, due I think to the North Norfolk posh set who have arrived from London. They search for quaint (but non-existent) ways to pronounce words, like Cly, Stewky, Hookum etc. But the very old people born and bred here are I feel the best sources. Also, the Norfolk accent is very different from the Norwich one, which is much more nasal.
