Neanderthal means Neander Valley - without the thal it sounds more mundane.

Towns all over England end with -caster or -chester or even are just Chester. Once you realize it's the word for camp(fire), they don't sound as cool. Lan(d)-camp, port-camp, Camp, Dor-camp, East Camp, West Camp, Camp-field, Camp-ville, etc.

BTW, I vote for campfire rather than camp because the Russian word for campfire is koster (sounds like cost your), even though some dictionaries claim it comes from camp.

QED a good vocabulary spoils your sense of fun.

Sadly, City names with bad translations are often full of such examples.
