Truro is "Trow"

The village of Mousehole is pronounced "Muzzle",an unpleasant inhabitant thereof being,by extension,an "Arzzle" (obviously !).

St John is usually ,in England anyway,"Sinjen", so ,when I am in Sidmouth,I often nip down the road to "Ottery Simmery".

Launceston is "Larnston",but I always say "Lorn-cess-ton" to annoy "Hawker" .
