How to pronounce "River Thames" in London (and why it is pronounced that way)
The proper pronunciation is River "(Temz)", rhyming with "gems", not "Thames" rhyming with "James."
My high school history teacher told me it was because King George I, who was born and lived in Germany for over 50 years before becoming King of England (complicated succession business), couldn't pronounce the "h" in Thames and the mispronunciation stuck.
I learned today that was completely bogus. "Thames" is simply a derivation of the word "Temesas", the Celtic name for the river. The "h" was added in during the Renaissance to give a "Greek feel" to the name (go figure), but the pronunciation stayed true to the original spelling.
