[dancing spawn of ungoliant]

My stumbling block was words that had an 'a' with two dots in it, Eä and Eärendil, for example. It took me ages to remember that the 'ä' is pronounced like an 'a' in Elvish (and Finnish) because 'ä' is a quite common wovel in Finnish and it's pronounced like an 'a' in the word "dad".

I always pronounced Celeborn and Cirdan, Seleborn and Sirdan.

Sounds very familiar... I was particularly irritated to learn the right pronounciation since I used to think that Seleborn souded nicer.
