Default "Y1" component designation?

In article xpi%a.153222$Ho3.18533@sccrnsc03,
says...
it is a crystal or ceramic resenator, possibly 3.58mHz


This makes me wonder: Where did some of these letter designations come
from? Why are most IC's labeled U1, U2, etc..? I'm guessing Y is from
crYstal? How about L (or sometimes E) for inductors? Q for transistors?
