Linguistic Notes on Norwich and Norfolk Place-names for Language and Communication Students
To say "Great Yarmouth” is also to identify oneself as an outsider. It is never so called by local people, who call it simply Yarmouth. (There was originally a Little Yarmouth across the River Yare in what is now Gorleston.)
As far as pronunciation is concerned, the best-known traps for the unwary newcomer are:
Costessey= “Cossy”; Wymondham “Wind’m”; Happisburgh “Hayzbruh”; Garboldisham “Garblesh’m”, and Tacolneston “Tackleston”.
Quite a lot of people pronounce Cley as “Cly”, but the correct pronunciation is “Clay” – the name actually derives from “clay, clayey soil”. Hunstanton is traditionally pronounced “Hunston”.
And, just outside Norfolk, Bungay is “Bung-gy” [with a hard ‘g’), and Lowestoft
is “Lowst’ff”, with the first syllable as in “low".
