[HANASHIR:12250] question on words. one word, actually.

[Batiya5723 <Batiya5723...>]

I have been asked to lead a discussion about Jewish music and one of the 
questions has to do with using one of the zillion names of God.
Because I am schooled in the Reform tradition it feels okay for me to use -- 
well, let's call it the A-word for now -- in reference to God. But other Jews 
prefer to avoid use of this word by substituting a less, um, loaded word in 
its place; or by doctoring a name by changing a consonant to alter the 
pronounciation and thereby avoid the actual name altogether.
How did this tradition come about? What do people think about it? And can 
anyone recommend a good book that would help be feel better prepared to 
discuss this phenomenon?
Thank you in advance --Beth Hamon
