Yeah, it's a tough one, because the name comes from German. If it were any other country, the Tea-Drinkers would probably be correcting everyone ("Rim-skee-KorSOCKoff"). Instead, they stick with their own little stupidities.
It is Neander-Thal. ‘Valley of Neander’ - the valley where the first bones of Neanderthal man were found.
The fact that Neander means ‘New Man’ is a coincidence. Anyone who can use the internet can discover the reason why the valley was so named.
Addendum. SunkenCiv: your ignorant snark added nothing to this thread. Leave it out next time.
