I thought I'd posted something about place names before but it is lost in the ether, so here goes ...

I can think of quite a few place names that cause visitors problems, not all of them Welsh - see Rhydycroaesau and Llanfyllyn http://wordsmith.org/board/showthreaded.pl?Cat=&Board=words&Number=2542
as well as the wonderful place mentioned at http://wordsmith.org/board/showthreaded.pl?Cat=&Board=miscellany&Number=1580

Shrewsbury has three different pronunciations, according to where the speaker comes from. Likewise Southwell in Nottinghamshire is a name which helps to differentiate locals from outsiders. I'm sure that there are lots of others.

Personal names like St. John and Cholmondley cause amusement for their people in the know.
