When spelling, every letter in the Alphabet is pronounced by a single syllable, with the only exception of W being pronounced "double-U". (Fun fact, in German it's approximately pronounced like the "ve" in very, but in some strike of cosmic justice Y is pronounced "Yps-e-lon") Why is that? Is there any at least semi-officially accepted one-syllable alternative pronunciation of W?
I checked some related post, e.g. this one, but they are more concerned with the "Why?" instead of the "Why not different?"
