The place names of Britain can trap an inexperienced broadcaster or speaker. They are often said quite differently from how they might seem.
Some examples follow:
Leicester, Gloucester and Worcester are pronounced LEST-uh, GLOS-tuh and WOOS-tuh. [IPA: ˈlestə, ˈglɒstə, ˈwʊstə]
Hertford (Hertfordshire). Pronounced HAHT-fuhd and sometimes HAH-fuhd.
[IPA: ˈhɑ:tfəd, ˈhɑ:fəd]
By the way, Wikipedia provides links to early references to the town as Herutford. "Herut" is the Old English spelling of "hart", meaning a fully mature stag. And so we have a ford, where harts (stags) are found.
A town which appeared in early maps as Darby or Darbye has for centuries been spelt Derby, but is still pronounced DAH-bee. [ˈdɑ:bɪ]
Warwick, Keswick, Berwick, Chiswick, Dulwich, Norwich, Greenwich, etc.
These British places are pronounced without the "w", it would seem for much the same reason we leave out the "w" when we say write, wreck, answer, sword, and so on.
The BBC Oxford Pronouncing Dictionary of Names and other sources provide examples of more "curly ones". IPA transcriptions are included. In some cases, there are several acceptable pronunciations:
