In a discussion about how to covertly hide a spell, it was brought up that you might be able to disguise a spell with a verbal component by sneaking the spell component words into a normal conversation. Mxyzplk gives an example:
"Well, I was talking to <krztl quaranda> the other day and she said <shirak gumptiona>!"
Does a spell with a verbal have to have well-formed words in the correct order and nothing else, or can the spell fire off regardless of filler speech interjected into it?
Are there any examples in D&D material that reference the actual structure of a verbal component? What about Pathfinder's Words of Power?
