A fjord by any other name?

Here's something random that I learned when I recently went to New Zealand on a whirlwind holiday. Milford Sound -- THE Milford Sound -- is actually not a "sound" at all. It is in fact a fjord.

The distinction is in how it is formed. A fjord is carved out by glaciers while a sound is created by rivers and filled with the ocean. Milford Sound was carved out by glaciers.

Seeing as it was quite the oversight, and it would not do to change the name, a presumably worried group of New Zealanders then scratched their heads at what to do to make up for their mistake. Then one -- or perhaps all -- came up with the idea of naming the park and the part of New Zealand after their geological properties, and that's how "Fiordland" got its name.

Sure the spelling isn't quite right, but you get the general idea...
