I can understand dental_floss' rationale. But I really like the clerical spells having pious names. ..But I also have a web-browser open all the time with various ADOM Guidebook and Wiki pages open too, so I just do a quick google for the spell-name, and one of the top hits has the entry with the clerical and normal names side by side. (I also used to have the manual open in a text-editor, and did a quick search that way .. it's become routine now as priest is my favourite class. :)
So, my ADOM behaviour seems to indicate dental_floss has a good point, but I really like this naming convention. Maybe the appropriate compromise would be to have the manual entry for the spell pop up when you mouse over it, with the clerical version of the name first, if you're a cleric/priest/paladin/etc, and the normal spell name in parenthesis after it?
For example, if you moused-over Lesser Divine Touch (either the spellbook, or the spell in your spell list) you'd see:
Lesser Divine Touch (Stun Ray)
This spell dazes the targets and makes them move with little coordination.
But if you were a wizard/elementalist/etc, you'd just see:
Stun Ray
This spell dazes the targets and makes them move with little coordination.
